    AGEE, Circuit Judge:
    In this death penalty case, Mikal Mahdi (“Mahdi”) appeals from the district court’s
    denial of his 
    28 U.S.C. § 2254
     petition for habeas relief and his accompanying request for
    supplemental expert funding. We granted a Certificate of Appealability (“COA”) on five
    issues. See 
    28 U.S.C. § 2253
    . For the following reasons, we affirm the district court’s
    judgment in its entirety.
    I.
    As a federal court reviewing a state court’s decision under § 2254, we do so through
    a narrow lens, “carefully consider[ing] all the reasons and evidence supporting [it].” Mays
    v. Hines, 
    141 S. Ct. 1145
    , 1149 (2021) (per curiam). We must examine the record in its
    entirety as it existed before the state post-conviction relief (“PCR”) court at the time of its
    decision. Cullen v. Pinholster, 
    563 U.S. 170
    , 182 (2011). Only upon a full review of the
    record may we consider whether that court’s judgment was the result of “an error that lies
    beyond any possibility for fairminded disagreement.” Mays, 141 S. Ct. at 1146. 1
    Unsurprisingly, this case has an extensive procedural history. We begin by
    recounting Mahdi’s conduct that gave rise to his convictions and provide an overview of
    the plea and sentencing hearings in the South Carolina state trial court (the “trial court”).
    We then turn to Mahdi’s first PCR proceeding in state court—which resulted in the
    decision we are reviewing here—and focus on his claims alleging ineffective assistance of
    1
    Internal quotation marks, citations, and alterations have been omitted unless
    otherwise indicated.
    2
    counsel (“IAC”) under Strickland v. Washington, 
    466 U.S. 668
     (1984), and its progeny.
    After reviewing Mahdi’s second state-court PCR proceeding, we summarize the federal
    district court’s denial of his request for supplemental expert funding and his § 2254
    petition.
    A. The Underlying Conduct
    Then-South Carolina Supreme Court Chief Justice Jean Hoefer Toal described
    Mahdi’s criminal acts as “particularly heinous,” emphasizing that in her time as a jurist,
    she “ha[d] seen few cases where the extraordinary penalty of death was so deserved.”
    Mahdi v. State, 
    678 S.E.2d 807
    , 808–09 (S.C. 2009) (Toal, C.J., concurring). We recite the
    following from her opinion concurring in that court’s rejection of Mahdi’s direct appeal
    and affirming his death sentence:
    On July 14, 2004, [Mahdi], then a resident of Virginia, embarked upon a
    crime spree that would span four states. [He] stole a .380 caliber pistol from
    his neighbor, a set of Virginia license plates, and a station wagon. [Mahdi]
    left Virginia and headed to North Carolina.
    On July 15, [Mahdi] entered an Exxon gas station in Winston-Salem, North
    Carolina armed with the .380 pistol. [He] took a can of beer from a cooler
    and placed it on the counter. The store clerk, Christopher Jason Boggs, asked
    [Mahdi] for identification. As Boggs was checking [his] identification,
    [Mahdi] fatally shot him at point-blank range. [Mahdi] fired another shot into
    Boggs as he lay on the floor. [Mahdi] then attempted unsuccessfully to open
    the store’s cash register. [He] left the store with the can of beer, and headed
    to South Carolina.
    Early in the morning of July 17, [Mahdi] approached Corey Pitts as he sat at
    a traffic light in downtown Columbia, South Carolina. [Mahdi] stuck his gun
    in Pitts’ face, forced him out of his car, and stole Pitts’ Ford Expedition.
    [Mahdi] replaced the Expedition’s license plates with the plates he had stolen
    in Virginia, and headed southeast on I-26.
    3
    About thirty-five minutes down the road, [Mahdi] stopped at a Wilco Hess
    gas station in Calhoun County and attempted to buy gas with a credit card.
    The pump rejected the card, and [Mahdi] spent forty-five minutes to an hour
    attempting to get the pump to work. Due to his suspicious behavior, the store
    clerks called the police. Aware that the clerks’ suspicions had been alerted,
    [Mahdi] left the Expedition at the station and fled on foot through the woods
    behind the station.
    About a quarter to half mile from the station, [Mahdi] came upon a farm
    owned by Captain James Myers, a thirty-one year veteran law enforcement
    officer and fireman. [Mahdi] broke into a work shop on the Myers property.
    Once inside the work shop, [Mahdi] watched television and examined
    Myers’ gun collection. [Mahdi] found Myers’ shotgun and used the tools in
    the shop to saw off the barrel and paint it black. [Mahdi] also took Myers’
    .22 caliber rifle and laid in wait for Myers.
    That day, Myers had been at the beach celebrating the birthdays of his wife,
    sister, and daughter. Myers had visited with his father before returning to his
    farm. Upon arriving at the farm, Myers stopped by the work shop, where he
    was confronted by [Mahdi]. [Mahdi] shot Myers nine times with the .22 rifle.
    [Mahdi] then poured diesel fuel on Myer’s [sic] body and set the body on
    fire. [Mahdi] stole Myers’ police-issued truck, and left with Myers’ shotgun,
    his .22 rifle, and Myers’ police-issued assault rifle.
    Later that evening, Myers’ wife, also a law enforcement officer, became
    worried when Myers did not return home. Mrs. Myers drove to the work shop
    and discovered Myers’ burned body lying in a pool of blood.
    [Mahdi] escaped to Florida, where he was spotted by police on July 21
    driving Myers’ truck. Fleeing the police, [Mahdi] abandoned the truck [and
    proceeded] on foot in possession of the assault rifle. When cornered by
    police, [Mahdi] abandoned the rifle and was eventually taken into custody.
    
    Id. at 809
    .
    B. The Plea Hearing
    On August 23, 2004, the Calhoun County, South Carolina, Grand Jury indicted
    Mahdi for Captain Myers’ murder, second-degree burglary, and grand larceny. The State
    filed a Notice of Intent to Seek the Death Penalty and a Notice of Evidence in Aggravation,
    4
    alleging Mahdi killed Captain Myers: (1) “while in the commission of burglary”; (2) “while
    in the commission of robbery while armed with a deadly weapon”; and (3) “while in the
    commission of larceny with use of a deadly weapon.” J.A. 935 (citing 
    S.C. Code Ann. § 16-3-20
    ). The State later filed an amended Notice of Evidence in Aggravation, alleging an
    additional statutory aggravating factor: (4) the murder occurred during “the performance
    of [Captain] Myers’ official duties as a law enforcement officer.” J.A. 937.
    In November 2006, Mahdi went to trial. Following three days of voir dire, the trial
    court judge, Judge Clifton Newman, empaneled a jury. Soon thereafter, the Solicitor
    announced “a security issue,” explaining that court security had discovered “a homemade
    handcuff key” in Mahdi’s pocket during a brief recess. J.A. 1167. Mahdi “indicated . . . he
    had made [the key] in the department of corrections. He had been transporting it in his
    mouth and ha[d] attempted to use it at the jail, but he hadn’t had the opportunity to use it
    [at the courthouse].” J.A. 1168. The Solicitor and Sheriff recommended—and Mahdi’s
    counsel, Glen Walters, Sr., and Joshua Koger, Jr. (collectively “trial counsel”) agreed—to
    put his legs in irons and chains for the duration of the trial.
    After the trial court resolved the security issue and dismissed the jurors for the day,
    the proceedings continued in chambers at Mahdi’s trial counsel’s request for “an ex parte
    conversation . . . concerning this case and a possible resolution.” J.A. 1173–74. There, they
    informed the court that Mahdi was considering “whether he should proceed forward with
    trial or whether he should go in front of [the trial court] and plead guilty.” J.A. 1179. To
    that end, Walters represented—in Mahdi’s presence—the following:
    5
    [He] discussed with [his] client options that are available with regards to this
    case. Mr. Mahdi is very intelligent and in conveying the options to him, of
    course, he’s aware of the fact that there are two phases to a trial, the guilt
    phase and also the sentencing phase, if it should reach that point.
    One option that was discussed with Mr. Mahdi was with regards to the guilt
    phase. And, of course, there’s been a discussion with regards to the balancing
    of options or the lesser of two evils in that process.
    What’s been conveyed to Mr. Mahdi is . . . that there are no guarantees with
    regards to either process. We have a jury that’s been empaneled and there are
    certain pluses and minuses with that jury. And, of course, Mr. Mahdi’s in a
    position where he’s saying, well, what about the judge. And, of course, Your
    Honor’s conveyed from the beginning that there is no policy by this Court
    that they will agree to a plea or agree to a certain sentence being rendered.
    So I’ve explained to him that there are no guarantees wherever you go. And,
    of course, he’s pondering the issue of whether he should proceed forward
    with trial or whether he should go in front of Your Honor and plead guilty.
    Of course, with the second phase with regards to the sentencing phase, he
    has been informed that the State will have to put up their case and information
    and, of course, he’ll be allowed to put up information. The question is
    whether he will do that in front of a jury or whether he will do that in front
    of a judge. And, again, there are no guarantees and there are pluses and
    minuses with regards to either option that he pursues.
    J.A. 1178–79. Mahdi never interjected or contradicted counsel’s representations. The court
    allowed Mahdi to consider his options overnight.
    The next morning, the trial court resumed the ex parte conference with trial counsel
    and Mahdi and explained that
    the law provides that if the defendant pleads guilty, the sentencing
    proceeding will be conducted before the Judge. And that’s statutory. And
    that’s the same as in any criminal proceeding that if a person pleads guilty,
    the Judge does the sentencing.
    ....
    And this is certainly not . . . being mentioned to suggest that that is advisable
    or not advisable. It’s simply the law. . . . And after more closely reviewing
    6
    the statute and also the case of State v. Downs, it is clear that sentencing is
    conducted by the Judge in any capital case where a defendant pleads guilty.
    J.A. 1183–84. Mahdi indicated that he understood and agreed to plead guilty to all charges. 2
    During the subsequent plea hearing, Mahdi’s counsel averred that he had
    explained to [Mahdi] his constitutional rights, including the right to have a
    jury trial and the rights to have the jury determine whether his sentence would
    be life without the possibility of parole, if he were to be found guilty during
    the guilt phase of the trial, or the jury could return a verdict for death[.]
    J.A. 1193. The court also detailed the mechanics of a jury trial and the rights Mahdi would
    waive by pleading guilty. Specifically, the trial court emphasized that “in order for a jury
    to find [him] guilty, all 12 jurors must unanimously agree” and “in order for a jury to
    recommend a death sentence, . . . all 12 jurors must agree to recommend the death
    sentence.” J.A. 1197. Mahdi indicated that he understood he had “the constitutional right
    to have the jury decide [his] guilt or innocence and, also . . . the constitutional right to have
    the jury determine [his] sentence.” J.A. 1197.
    The trial court further explained that if it were to accept Mahdi’s guilty plea, “the
    jury [would] have no role in [his] sentencing and the decision as to what sentence [he
    would] receive [would] be left solely up to [the trial court].” J.A. 1198. The court then
    engaged in the following dialogue with Mahdi:
    2
    At the trial court’s insistence, Mahdi met with Dr. Michael Cross to assess his
    competency before entering the plea. Dr. Cross testified that Mahdi “understood the risks
    and benefits of entering into this plea . . . and had a rational understanding of both, what
    the possible consequences for each”—i.e., trial and sentencing by a jury or guilty plea and
    sentencing by a judge—“[could have] be[en].” J.A. 1189. Mahdi also “had a good
    understanding of the process,” “had a factual knowledge of the legal system,” and knew
    “what he [was] doing.” J.A. 1190.
    7
    The Court:    And do you voluntarily give up such a right [to be tried and
    sentenced by a jury]?
    Mahdi:        Yes, sir, Your Honor.
    The Court:    And do you understand what waiving that right means?
    Mahdi:        I do, Your Honor.
    The Court:    And what does it mean?
    Mahdi:        It means I’ve given up all of my rights to a 12 party jury. And
    I just admitted guilt to the crimes I’m being charged with.
    ....
    The Court:    And have you discussed with your lawyers thoroughly the
    constitutional safeguards that you have and the essential
    protections inherent in a jury trial?
    Mahdi:        I was made fully aware of that by my attorneys.
    J.A. 1198, 1200. Mahdi further indicated that he was “satisfied with the services of [his]
    attorneys in this case,” that they had represented him effectively, and that they had “done
    everything to the full extent of their power to assist . . . and defend [him].” J.A. 1201–02.
    The court accepted Mahdi’s guilty plea and scheduled the sentencing hearing.
    C. The Sentencing Hearing
    Over the course of three days, the trial court “heard additional evidence in
    extenuation, mitigation [and] aggravation of the punishment” as well as “the arguments of
    counsel for or against the sentence to be imposed.” J.A. 1661. The State reiterated its
    intention to seek the death penalty, while Mahdi’s counsel urged the trial court to sentence
    him to life without the possibility of parole.
    1. The State’s Evidence in Aggravation
    The State sought to prove that Mahdi had “killed Captain Jimmy Myers . . . because
    his heart and mind [were] full of hate and malice.” J.A. 1223. In doing so, the State called
    8
    twenty-eight witnesses to testify about: (1) the events leading up to Captain Myers’ murder;
    (2) the murder; (3) Mahdi’s arrest; (4) his prior criminal history; (5) his behavior while in
    custody; and (6) the impact Captain Myers’ death had on his friends and family. The
    testimony most relevant to our present analysis is summarized below.
    a. The Events Leading to Captain Myers’ Murder
    Detective Michael Poe from the Winston-Salem, North Carolina Police Department,
    testified about and introduced a surveillance tape showing Mahdi’s execution-style murder
    of Boggs on July 15, 2004. Specifically, the tape showed Mahdi’s movements throughout
    the store before “shoot[ing] [Boggs] in the face with the gun[,] . . . com[ing] up on to the
    counter[,] . . . and fir[ing] a second shot at [him].” J.A. 1420. The trial court viewed the
    tape over trial counsel’s objections.
    Corey Pitts, Mahdi’s carjacking victim from Columbia, South Carolina, recounted
    that at around 3:25 AM on the morning of July 18, 2004, he was driving home. As he was
    sitting at a traffic light waiting to make a left turn, Mahdi approached his car, held a gun to
    his face, and directed Pitts to “[g]et the fuck out and walk.” J.A. 1380.
    b. Captain Myers’ Murder
    Officer Stephen Curtis, a former deputy sheriff in Columbia, was among the first
    responders to the scene of Captain Myers’ murder. He testified that he found Captain Myers
    lying “face down in the workshop area.” J.A. 1392. “There were several matches on him,”
    all of which were spent, “and there was a heavy odor of gasoline.” J.A. 1394. Officer Curtis
    testified that investigators recovered nine shell casings from the scene which were later
    9
    matched to Captain Myers’ .22 caliber rifle discovered in Mahdi’s possession upon his
    arrest.
    Janice Ross, the forensic pathologist who performed Captain Myers’ autopsy,
    testified that his clothing “was partially burned and smelled of diesel fuel.” J.A. 1544. “He
    had some singeing of the hair in the back of the head and some thermal injury, burning of
    the skin, on the back and around the sides of the abdomen.” J.A. 1545. Captain Myers also
    had nine gunshot wounds: three in his head, four in his chest, one in his abdomen, and one
    in his left hand. All but two would have been fatal or potentially fatal.
    c. Mahdi’s Arrest
    Sergeant Darren Frost from the Satellite Beach, Florida, Police Department testified
    about the circumstances surrounding Mahdi’s arrest. According to Sergeant Frost, Mahdi
    led officers on a brief chase while driving Captain Myers’s stolen truck. As Mahdi stepped
    out of the vehicle and began to flee, Sergeant Frost saw him carrying Captain Myers’ stolen
    rifle. Sergeant Frost testified that he drew his service weapon and directed Mahdi to drop
    the gun. Mahdi turned towards him, with his “hand . . . close to the trigger.” J.A. 1232. As
    Sergeant Frost prepared to fire, Mahdi dropped the weapon and ran.
    Sergeant Frost then released his canine, which tracked Mahdi to a condominium
    complex, where he was taken into custody. Sergeant Frost testified that he later “thanked
    [Mahdi] for not using [the weapon on him] . . . and allowing [him] to go home to [his]
    family that night,” stating that a round from the rifle “would have gone through [him], [his]
    vest and [anyone] standing behind [him]].” J.A. 1243. According to Sergeant Frost, Mahdi
    “looked at [him], [with] very cold eyes,” and said that the gun’s “selector was stuck on a
    10
    three shot and [he did not] think [he] could have . . . shot [Sergeant Frost], the other cop,
    and . . . that fucking dog.” J.A. 1243.
    d. Mahdi’s Criminal History
    The State called several witnesses to present Mahdi’s extensive criminal history.
    The testimony related to Mahdi’s juvenile convictions is summarized first before turning
    to his adult conduct.
    i. Juvenile Crimes and Convictions
    Sheriff James Woodley from Brunswick County, Virginia, testified that he first met
    Mahdi as a young teenager while investigating a report of stolen property. Mahdi, who was
    fifteen at the time, was later convicted of breaking in and entering a house where he stole
    “speakers, [a] tape player and also . . . a handgun, a .44 caliber magnum.” J.A. 1278.
    After Mahdi failed to appear for sentencing in June 1998, an officer attempted to
    execute an order to remand him to the Virginia Department of Juvenile Justice (“DJJ”). At
    the same time, the officer tried to serve a show cause order on Mahdi’s father, Shareef.
    When the officer arrived at Mahdi’s grandmother’s house—where they were living—
    Shareef came out, read the orders, said, “We’re not going,” and proceeded to run back into
    the house. J.A. 1278. Sheriff Woodley eventually arrived at the scene and spoke with
    Shareef through a window. At that time, “the other officers [were] putting on their gear,
    the bullet proof vests and getting weapons out of the vehicle.” J.A. 1279. Sheriff Woodley
    heard Mahdi “holler to his father” that “[t]he mother fuckers got guns out there.” J.A. 1279.
    Around nine hours after the standoff began, officers breached the house and arrested Mahdi
    and Shareef. After he was in custody, Mahdi told the officers escorting him that he was
    11
    “going to kill a cop before [he] die[s].” J.A. 1280. Sheriff Woodley made clear in his
    testimony that both Mahdi and his father were responsible for the standoff.
    Officer Mike Koehler from the Richmond City Police Department testified about an
    encounter he had with Mahdi in November 2000. Officer Koehler went to Mahdi’s “house
    with another officer . . . to serve a summons on him for slashing his mother’s tires” along
    with “an outstanding detention order.” J.A. 1307. Officer Koehler tried to take Mahdi into
    custody, but Mahdi “got upset” and “started to pull away.” J.A. 1308. The officers wrestled
    with him, and Mahdi reached for one of their guns. Eventually, after using pepper spray
    and an ASP baton, the officers were able to subdue Mahdi. He later told Officer Koehler
    that “he slashed his mother’s tires because she wouldn’t come to the door when he
    knocked,” referring to her as “a crazy bitch” and saying “that he should have killed her.”
    J.A. 1309–10. Mahdi also “begg[ed]” the officers to “shoot him.” J.A. 1310.
    ii. Adult Crimes and Convictions
    Turning to Mahdi’s adult conduct, the State called Moises Rivera, a maintenance
    worker from Richmond, Virginia. Rivera said that on April 17, 2001, he discovered Mahdi
    standing outside of a window to an apartment where he did not live. Mahdi immediately
    “jumped [Rivera] and [they] started fighting.” J.A. 1323. During the exchange, Mahdi
    stabbed Rivera once in the arm and five times in the back, puncturing one of his lungs.
    After Mahdi ran away, Rivera “took three steps, collapsed, started coughing up blood and
    . . . was rushed to [the hospital].” J.A. 1323.
    Mahdi was convicted of malicious wounding and served thirty-nine months of
    active incarceration. Though he was also sentenced to fifteen years of supervised probation,
    12
    Joseph Owen, Mahdi’s probation officer, testified that he only served two months before
    beginning the crime spree that ended in Captain Myers’ murder.
    Amanda Jean Weaver, Mahdi’s next-door neighbor from Brunswick County,
    testified that he was anything but compliant during his time on probation between May and
    July 2004. Mahdi told her that he “was doing a little drug pedaling or pushing or whatever,”
    J.A. 1349—i.e., selling marijuana—and that he “was going to knock [someone] off,” J.A.
    1363.
    Weaver testified that she owned a .380 caliber semiautomatic pistol at that time. On
    July 13, 2004—the day before Mahdi left Virginia for North Carolina—Weaver returned
    home and discovered there had been a break-in, though nothing initially appeared to be
    missing. The following week, upon seeing news coverage of Mahdi’s arrest, Weaver
    recognized his picture and began to fear for her safety. She went to retrieve her gun and
    discovered it was missing. Weaver later learned that Mahdi had stolen it and used it to kill
    Boggs. 3
    e. Mahdi’s Behavior in Custody
    The State called several witnesses to testify about Mahdi’s failure to adapt to
    incarceration. We begin by summarizing his time at the DJJ before turning to his terms of
    incarceration with the Virginia and South Carolina Departments of Corrections (“VDOC”
    and “SCDC,” respectively).
    Weaver also testified that Mahdi believed “all white people were white devils,”
    3
    J.A. 1357, and that he “had a very strong dislike for police officers,” J.A. 1358.
    13
    i. The DJJ
    The State called Linda Coulson, a former counselor at the DJJ’s Reception and
    Diagnostic Center, who worked as “part of an assessment team to evaluate all [committed]
    juveniles,” including Mahdi. J.A. 1285. Coulson testified that when she met Mahdi, he
    “was tested to have a full scale IQ of 108,” which is considered “in the upper average
    range.” J.A. 1288. During his intake interview, Mahdi “described himself as a quiet person
    who [was] always up to something. He denied . . . [having] any strengths except for robbing
    people.” J.A. 1288. Mahdi also advised Coulson “that he had been involved in selling crack
    cocaine.” J.A. 1289. He relayed his history of escapes and attempts to elude law
    enforcement. At bottom, Mahdi’s comments suggested to Coulson “that he had little
    respect for the rights and property of others. He expressed no remorse” or “empathy for the
    impact of his acts upon others.” J.A. 1290. In her final assessment, Coulson observed that
    Mahdi was “the product of a dysfunctional single parent family characterized by a lack of
    involvement with his mother, an absence of a positive adult role model, instability,
    unemployment, and a lack of structure and supervision.” J.A. 1703.
    Barbara Amos, who worked as a DJJ counselor, introduced portions of Mahdi’s
    records from his time in custody there. These records reflected: Mahdi’s regular meetings
    with counselors; consistent efforts by Shareef and Mahdi’s grandmother, Nancy Burwell
    (“Nancy”), to visit and communicate with him and his counselors; as well as his various
    disciplinary violations for conduct including, among other things, attempted assault on an
    officer and the use of threatening language/behavior. At one point Mahdi made “suicidal
    statements” to his counselor before stating that “he would become homicidal first. He gave
    14
    very graphic descriptions of how he would hurt others. He also graphically described how
    [DJJ staff] would find [Mahdi’s victims and him after he committed suicide] (i.e.
    ‘hanging’).” J.A. 1978–79.
    ii. VDOC
    To introduce Mahdi’s VDOC records, the State called Cindy Collins, VDOC’s
    criminal records manager. According to a summary of Mahdi’s disciplinary record, he had
    a couple dozen violations, including setting fires, “[p]ossession of a sharpened instrument,”
    and “[a]ssault on [a] non-inmate.” J.A. 1698. Mahdi was transferred twice during his time
    in VDOC’s custody due to his “continued poor institutional adjustment and increase in
    security level.” J.A. 1698.
    iii. SCDC
    The State called several SCDC officers to testify about Mahdi’s behavior while
    awaiting trial. Officer Henry Johnson spoke about a disciplinary hearing where Mahdi was
    charged with striking a correctional officer (who suffered a concussion). During the
    hearing, Mahdi said that “the next chance he [got], he[] [was] going to . . . kill that mother
    fucking officer. . . . The first chance he [got], he would finish him off.” J.A. 1465. Officer
    Johnson also testified about a search he conducted in Mahdi’s cell where he discovered
    “[s]ome rope and . . . some pieces of metal.” J.A. 1466. Officer Terrance Prioleau testified
    about a separate search where officers discovered a piece of metal Mahdi had hidden in a
    hole in the wall.
    Officer Janet Driggers testified about a grievance form she received from Mahdi,
    where he wrote,
    15
    I cannot be diplomatic with you people, so my last action would be to kill
    you. Why not? You’re no good to anybody. I could easily get someone to
    murder you. What is wrong with you, bitch? I bet you’ll respond quick to
    this, won’t you? You people think this shit is a game.
    J.A. 1482. Officer Driggers testified that “[i]n [her] capacity as a grievance coordinator,”
    this was the only time she “was ever threatened to be killed.” J.A. 1489.
    SCDC disciplinary officer Annie Sellers testified that Mahdi made additional threats
    during the subsequent disciplinary hearing. Even “[a]s he was being removed from the area
    and while he was out in the hallway, he was still making threats towards [Officer
    Driggers].” J.A. 1497.
    Eventually, SCDC officials determined that Mahdi should be moved to more
    restrictive custody in the Kirkland Maximum Security Unit (“Kirkland”). Captain Gary
    Lane testified that Kirkland is “a 50 bed facility” reserved for “the worst of the worst
    inmates in the State of South Carolina.” J.A. 1500. Within the facility, there are six cells in
    what is called the “High D Wing,” where “the lights are kept on 24 hours a day, seven days
    a week” and inmates are monitored by video cameras “24 hours a day.” J.A. 1501. That is
    where the SCDC housed Mahdi, meaning “he [was] one of the six most secure inmates in
    the whole department of corrections” at the time of his sentencing. J.A. 1502.
    Captain Lane testified about separate incidents at Kirkland when they discovered
    various contraband in Mahdi’s cell including: a “hammer-like weapon,” J.A. 1502; “two
    pieces of a metal, one sharpened to a point,” J.A. 1506; and pieces of “knotted rope,” J.A.
    1506.
    f. Victim Impact Statements
    16
    Finally, the State called several witnesses, including Captain Myers’ father, wife,
    and daughter, as well as his colleagues and friends on the police force, who testified about
    Captain Myers’ character and the impact his death had on them.
    2. Mahdi’s Evidence in Mitigation
    Mahdi’s counsel began their mitigation presentation by asking the trial court for
    mercy, arguing that he “took full responsibility . . . for what he did” by pleading guilty,
    “that at the time of this particular crime, . . . he was 21 years of age and very young,” and
    that he had a troubled childhood. J.A. 1224. No laypersons testified on Mahdi’s behalf. Nor
    did he take the stand. Instead, trial counsel called two expert witnesses: James Aiken and
    Marjorie Hammock.
    a. James Aiken: Prison Adaptability
    Aiken, a former warden and prison adaptability expert, testified that the SCDC was
    equipped to handle Mahdi and that he would likely present no future threat while
    incarcerated. Though Aiken considered Mahdi’s disciplinary infractions “serious,” he
    testified that “when you compare [Mahdi’s] contraband issues and the behavior issues . . .
    to the type of population that [the SCDC has] to manage, it’s fairly reduced.” J.A. 1565.
    The conduct was “[n]ormal and routine” and “a reflection of an immature boy in a big
    prison system.” J.A. 1567. According to Aiken, Mahdi was “not demonstrating . . .
    predator[y] behaviors,” J.A. 1566, i.e., he did not have “total control to call a signal and
    have an officer killed” or “caus[e] a riot between two rival gangs,” J.A. 1581. Mahdi also
    was not “a person with connections with international terrorists that [could] call hits on
    17
    officials within the prison systems.” J.A. 1581. He was, by Aiken’s account, simply
    “immature and [had] done some very violent, stupid things.” J.A. 1582.
    b. Marjorie Hammock: Biopsychosocial Assessment
    Mahdi’s second witness was Hammock, a licensed clinical social worker and
    assistant professor at Benedict College in Columbia, South Carolina, who had an extensive
    background in capital litigation. Before Mahdi’s sentencing, she had participated in twenty-
    five death penalty cases and had testified in fourteen of them.
    Hammock’s testimony centered on her biopsychosocial assessment 4 of Mahdi,
    which she prepared by “conducting interviews with family members, reviewing records,
    interviewing the defendant himself, [and] taking information from anyone who would give
    information about him, his life and his development.” J.A. 1595. Specifically, Hammock
    interviewed “someone who was a part of the community,” but “didn’t know much about
    [Mahdi],” J.A. 1595, as well as his paternal grandmother Nancy, his paternal uncles Nathan
    Burwell (“Nathan”) and Carson Burwell (“Carson”), and Lawanda Burwell (“Lawanda”),
    4
    A biopsychosocial assessment considers
    all of the social, the biological and the clinical factors, [and] the
    environmental factors about the defendant and bring[s] them together to
    really form a family or a social history. It examines at every aspect of the life
    to present a picture, particularly in this instance to give some understanding
    as to why we are here and that resulted in his being in this situation.
    J.A. 1594–95.
    18
    Carson’s wife. She also spoke with Shareef; Mahdi’s “mother, [Vera 5] Mahdi; [Corliss
    Artis (“Corliss”)], his maternal aunt; and Sophia Gee, . . . [an]other maternal aunt.” J.A.
    1596. Further, Hammock “reviewed a synopsis of [Mahdi’s] school records” and a mental
    health report from when he was a juvenile. J.A. 1596. 6
    Hammock described Mahdi’s childhood as “rather chaotic,” highlighting “the
    nature of the transience [and] the changes in his living circumstances.” J.A. 1597. She
    emphasized his parents’ “inability . . . to parent appropriately and correctly,” observing
    that Mahdi was “abandoned by his mother at quite an early age and that his father . . . had
    his own experiences which limited his ability to parent effectively.” J.A. 1597.
    Hammock testified at length about Shareef, whom she characterized as having “a
    lot of difficulties.” J.A. 1598–99. She conveyed Shareef’s
    experiences in desegregating the local school . . . and how traumatic that was
    for him. He was constantly in conflict with those around him. . . . [H]e
    considered himself unwanted.
    And so [Shareef’s] own childhood was difficult and he grew up in a situation
    feeling alienated from anybody else around him. He didn’t finish school. He
    was the only one in his sibling group that didn’t and that was a source of
    consternation between he and his family members.
    5
    Shareef changed his wife’s name from “Vera” to “Tilea” upon their marriage.
    Testimony and other evidence from the record use both names interchangeably to refer to
    Mahdi’s mother. For the sake of consistency, this opinion refers to her as “Vera.”
    Hammock described Vera as “very, very withdrawn” and indicated that she “did not
    want to participate in the interview at all, somewhat—really almost frightened about being
    involved with the family again.” J.A. 1605–06.
    6
    As discussed in greater detail below, Hammock did not work alone in compiling
    this information. Rather, along with trial counsel, she worked in conjunction with a private
    investigator, a mitigation investigator, a psychiatrist, and a forensic psychologist in their
    efforts to present mitigation evidence on Mahdi’s behalf.
    19
    This looked like an intact family that he grew up in, but they had their
    problems. There was alcoholism in the family and there was some neglect on
    the part of [Shareef’s father]. And, again, this also culminates in [Mahdi’s]
    father deciding to become a Muslim, change his name, which also brought
    some grief to the family.
    So [Shareef] . . . goes to the Marines, he gets out. . . . [H]e says he has an
    honorable discharge, but it was under some circumstances that really kind of
    compromised the nature of that discharge. . . . He has odd jobs, but he’s not
    really able to function well. There is some description of continuing
    depression and a number of incidents with law enforcement locally.
    At the age of 27, he meets and participates in an arranged marriage with
    [Vera,] a 16-year-old woman from Richmond, whose mother helped to
    arrange the wedding. [Vera was] not supportive of this, but she has no choice
    but to join the marriage and that marriage was conflict from the very, very
    beginning.
    [Mahdi’s] older brother [Saleem] is born and then [Mahdi] is born into this
    family, which is very unstable and chaotic. [Mahdi’s] father is not able to
    take care of his family. They move several times, ultimately ending back in
    Lawrenceville [Virginia] living with [Shareef’s] mother and not able to,
    again, sustain himself.
    There is a great deal of conflict described between . . . [Vera] and [Shareef].
    And this the children witnessed. Ultimately, [Mahdi’s] mother leaves the
    family and she describes her trying to get away from the abuse.
    J.A. 1599–1600. Hammock explained that Shareef attempted to care for the boys with his
    family’s help, but that “the relationship between [Mahdi’s] father and his grandmother and
    the other members of the family” was “constantly confrontational.” J.A. 1601. During this
    time, Vera was “forced to return . . . ostensibly to see the boys,” but that resulted in “some
    physical conflict. And she [left] again not to see her son for a number of years.” J.A. 1601.
    In 1991, when Mahdi was eight years old, he went to live with his paternal uncle
    and aunt-in-law, Carson and Lawanda, in Baltimore. They discovered he “simply could not
    20
    read even though he appeared to have other kinds of skills.” J.A. 1602. Hammock
    summarized Mahdi’s relevant school history:
    [H]e spends the second and the third grade in Scotts Branch Elementary
    School in Baltimore, Maryland. And he has uneven skills. He’s placed in an
    average math program, but . . . below average reading programs. And the
    narrative indicates that he needs improvement in a number of areas, including
    standards for behavior, showing respect for authority. And his reading and
    writing skills remained below grade level.
    That continues in the third grade and . . . it’s especially noted again the
    [unevenness] of his performance because he is considered by his teacher, in
    that year, that he was outstanding in science; however, the reading and the
    vocabulary and the spelling remain below average. It’s also noted several
    places where he clearly has poor self-esteem and often has difficulty with
    relationships with others.
    Ultimately, he leaves school [in Baltimore] and is placed in . . . a mental
    health facility [the “Carter Center”]. And after he is released . . . , he stays
    only with his aunt and uncle for a short period of time[.]
    J.A. 1604–05. By the time Mahdi returned to Brunswick County, his father was “known to
    be at odds with people in the community, with his own family and with law enforcement.”
    J.A. 1610. 7 But Mahdi “care[d] about his father, wanted more than anything else an intact
    family and an ongoing relationship, but that just didn’t happen.” J.A. 1610. That said,
    Mahdi never received “the consistent help in growing up and developing good skills and
    developing a sense of values. Even though folks tried, it just wasn’t consistent enough for
    him to learn how to do those kinds of things.” J.A. 1610.
    Hammock concluded that Mahdi had “been traumatized throughout his early life,”
    which “had an impact on his inability to make good choices, to have a good sense of himself
    7
    Hammock testified that Mahdi “live[d] with [his mother] for a very short period
    of time, . . . but it was not a good reunion. They did not get along at all.” J.A. 1607.
    21
    and others and to behave according to societal norms.” J.A. 1611. In short, she told the trial
    court, “[h]e never had really a chance to develop appropriately.” J.A. 1611–12.
    During Hammock’s testimony, trial counsel submitted a “Time Line” of the major
    events in Mahdi’s life, which included the following entries among others:
    • 1955[8]: Sareef [sic] enters a desegregated school, 5th grade. The
    experience was destructive. He was ridiculed, isolated, challenged
    physically by classmates, ignored or received negative feedback from
    some instructors. Felt traumatize[d] by the experience. Only child in the
    family that does not finish high school. Sareef [sic] described as disturbed
    as a young child, threw tantrums, Mother not emotionally available[.]
    ....
    • 1975: Sareef [sic] converts to Islam. Sareef [sic] involved in a series of
    misdemeanors locally all said to be racially motivated.
    • 1980–81: Sareef [sic] age 27 and Vera (Tilea) age 16 marry. The marriage
    is arranged by Vera’s mother, who is raising 16 children. Sareef [sic]
    changes Vera’s name to Tilea.
    ....
    • March 20, 1983: Mikal Mahdi born.
    ....
    • 1986: Vera (Tilea) leaves Sareef [sic] and the boys. Sareef [sic] lives in
    the Burwell home with the boys. Sareef [sic] took [the] boys to Richmond
    to live but could not keep a job, could not supervise or provide care for
    the boys. Sareef [sic] moves back to Lawrenceville. Sareef [sic] can not
    [sic] take care of himself or the boys.
    • 1988: Vera (Tilea) is taken to Lawrenceville from Richmond by Sareef
    [sic] who abuses her. Nathan rescues Vera. Mikal and Saleem witness
    more abuse and violence.
    ....
    8
    This date is obviously incorrect, given that the Time Line lists Shareef as being
    born in 1954.
    22
    • October 1991: Saleem sent to Texas to live with aunt. Mikal went to
    Baltimore to live with Uncle Carson and Aunt Lawanda Green Burwell.
    Carson described Mikal as very smart but unable to read at age 8.
    • August 23, 1992: Mikal involuntarily admission in a psychiatric facility
    after suicide threat/gesture and Mikal hospitalized Admission DX Axis I,
    Major Depression with suicidal ideation, adjustment disorder, R/O
    Adjustment Disorder, Axis II Developmental Reading Disorder, Axis III
    Hx of right arm and right leg fractures. Saleem comes back from Texas
    after disrupting his aunt[’s] home.
    • October 19, 1992: Mikal Discharged from Walter P. Carter Mental
    Health. Discharge DX Axis I Major Depression, Single episode. Mikal
    also becomes more disruptive in his uncle’s home in order to force his
    return to Lawrenceville to join his father and brother. He has become even
    more defiant after he learns that his brother has joined his father. The
    three reunite and live on Burwell property with the boys. This was an
    isolated place in the country and they often had no food, heat or money.
    • December 1997: Mikal sent to reception and diagnostic center—
    Culpepper in a juvenile facility for two counts of b & e and two counts of
    grand larceny. Mikal released from facility and Sareef [sic] sent Mikal to
    Richmond to live with his mother[.]
    • December 1997: Mikal committed to juvenile facility
    • April 2001: Mikal transferred VA Dept of Corrections
    J.A. 6322–23.
    D. The Trial Court’s Sentence and Mahdi’s Direct Appeal
    After hearing closing arguments and taking a day to deliberate, the trial court
    sentenced Mahdi on December 8, 2006. 9 The court began by summarizing the underlying
    facts before finding that the State had proven two of the alleged statutory aggravating
    9
    During the sentencing hearing, the trial court reaffirmed that Mahdi “understood
    that as a consequence of his guilty plea to murder while in the commission of burglary and
    grand larceny, that the Court would conduct a separate sentencing proceeding and
    determine whether he should be sentenced to life imprisonment without the possibility of
    parole or death.” J.A. 1661. Neither Mahdi nor his trial counsel objected to this statement.
    23
    factors beyond a reasonable doubt—that Mahdi had killed Captain Myers “while in the
    commission of burglary” and “while in the commission of larceny with use of a deadly
    weapon,” J.A. 935 (citing 
    S.C. Code Ann. § 16-3-20
    )—meaning Mahdi was eligible for
    the death penalty. 10
    The trial court then summarized the State’s evidence in aggravation, which it
    described as “compelling” and “established by clear and convincing evidence the
    defendant’s bad character and propensities.” J.A. 1665, 1668. “These incidents covered a
    period of over eight years showing [Mahdi] committing a series of crimes, including
    housebreaking, stealing guns, robbing people, selling crack cocaine, vandalism and
    malicious wounding.” J.A. 1665–66. And “[d]uring each of these periods of incarceration,
    Mr. Mahdi’s behavior was maladaptive, assaultive and demonstrated an utter disrespect for
    authority, including threatening the life of a detention officer.” J.A. 1667. Moreover,
    “[w]hile in safekeeping in the South Carolina Department of Corrections awaiting this trial,
    Mr. Mahdi made numerous threats to kill various department employees.” J.A. 1668.
    The trial court then considered and rejected each of Mahdi’s arguments in mitigation
    before announcing its decision:
    Defense counsel argues that the defendant’s youth should be considered by
    the Court in determining the appropriate sentence to be imposed.
    Mikal Deen Mahdi was 21 years old at the time of the murder of Captain
    Myers. When last tested at age 14, the defendant’s IQ was 108, slightly above
    10
    The trial court expressly found the State had not carried its burden of proof on the
    other statutory aggravating grounds and thus had not proved beyond a reasonable doubt
    that Mahdi killed Captain Myers “while in the commission of a robbery while armed with
    a deadly weapon” or “during or because of the performance of [Captain Myers’] official
    duties” as a law enforcement officer. J.A. 1664–65.
    24
    average. While this is a young age for such a serious crime, Mikal Deen
    Mahdi began his criminal career at an early age having entered the Virginia
    Department of Juvenile Justice at 14. He is experienced in the world of crime.
    By the time he committed these crimes, Mr. Mahdi was well aware of the
    severity of his crimes and the possible consequences.
    I have considered the defendant’s young age, but I have not afforded it great
    weight in reaching my decision. There is nothing about Mr. Mahdi’s age or
    mentality that in any way mitigates, excuses or lessens his culpability and
    neither should it be given any significant weight in the Court’s ultimate
    decision as to his sentence.
    I have also given consideration to what the defense contends to be the
    defendant’s turbulent and transient childhood and upbringing. In reviewing
    the testimony of Marjorie Hammock, the defense’s clinical social worker
    expert, there’s no reference to physical or sexual abuse suffered by the
    defendant. In addition, records of the Virginia Department of Juvenile Justice
    indicates [sic] that the defendant’s father, brother and grandmother
    continually expressed great care and concern for his well-being.
    While Mr. Mahdi’s family life may have been less than ideal, particularly
    without the presence of a loving and caring mother, I do not believe that his
    difficult childhood and family life contributed in any significant way to his
    senseless criminal activities; therefore, while I have considered this . . .
    nonstatutory mitigating circumstance, I do not believe that it should be given
    any significant weight in the Court’s ultimate decision as to the sentence to
    be imposed.
    The defense presented testimony from Mr. James Akin, a prison adaptability
    expert. Mr. Akin, a highly credential[ed] expert, testified concerning Mr.
    Mahdi’s potential adaptability to prison life.
    I have considered and reviewed Mr. Mahdi’s records regarding his prior
    behavior in various correctional institutions. He has consistently been
    disruptive and uncooperative and has threatened to kill prison employees.
    Officers have repeatedly found homemade weapons, ropes and other
    contraband in the defendant’s cell.
    During this trial, the defendant brought a homemade handcuff key into the
    courthouse with the intent of using it, if possible, to escape, thus, posing a
    serious threat to courtroom security. The Sheriff of Calhoun County testified
    that Mr. Mahdi stated to him that he made the key while being housed and
    monitored at the State’s highest security level facility.
    25
    While Mr. Akin gave impressive testimony, based on Mr. Mahdi’s behavior
    in correctional institutions throughout his adolescence and adult years, I do
    not believe that he is sufficiently adaptable to prison life for this
    nonmitigating [sic] circumstance to be given any significant weight in the
    Court’s ultimate decision as to the sentence to be imposed.
    The defense further . . . argues as a nonstatutory mitigation circumstance that
    the Court should consider the defendant’s guilty plea in determining the
    appropriate sentence to be imposed.
    The defendant’s guilty plea occurred during the fourth day of his trial
    following jury selection, but prior to the jury being sworn. This was one day
    following his attempted escape through the use of a homemade key. In
    addition, Mr. Mahdi has failed to demonstrate any remorse for his actions at
    any point in time known to this Court. Therefore, I conclude that no
    significant weight should be given to this nonstatutory mitigating
    circumstance and the Court’s ultimate decision as to the sentence to be
    imposed.
    ....
    My challenge and my commitment throughout my judicial career has been
    to temper justice with mercy and to seek to find the humanity in every
    defendant that I sentence. That sense of humanity seems not to exist in Mikal
    Deen Mahdi.
    ....
    Today, the defendant also seeks mercy, the same mercy that perhaps Captain
    James E. Myers sought for an instant before Mikal Deen Mahdi fired nine
    bullets into Captain Myers’ body from one of Captain Myers’ prized
    weapons before setting his body on fire with matches and diesel fuel
    belonging to Captain Myers. In extinguishing the life, hope and dreams of
    Captain Myers in such a wicked, depraved and consciousless [sic] manner,
    the defendant Mikal Deen Mahdi, also extinguished any justifiable claim to
    receive the mercy he seeks from this Court.
    J.A. 1669–74.
    The trial court sentenced Mahdi to death for Captain Myers’ murder, fifteen years
    of incarceration for second-degree burglary, and ten years for grand larceny, to be served
    consecutively. Mahdi appealed to the Supreme Court of South Carolina, raising a single
    26
    issue not relevant here. That court affirmed. Mahdi, 678 S.E.2d at 136. He did not appeal
    to the U.S. Supreme Court.
    E. The First State-Court PCR Proceedings
    After exhausting his direct appeals, Mahdi filed an initial pro se PCR application in
    South Carolina state court. The Supreme Court of South Carolina assigned the case to a
    judge (the “PCR court”), who subsequently appointed statutorily qualified counsel (“PCR
    counsel”). PCR counsel filed several amended PCR applications, raising the following
    relevant IAC claims:
    • The “Jury Sentencing Claim”: Trial counsel failed to adequately advise
    Mahdi of the advantages of jury sentencing, which resulted in him
    pleading guilty and purporting to waive his right to jury sentencing;
    • The “Mitigation Evidence Claim”: Trial counsel failed to adequately
    investigate, develop, and present mitigation evidence concerning
    Mahdi’s family, social, institutional, and mental health history; and
    • The “Judicial Sentencing Claim”: Trial counsel failed to assert that 
    S.C. Code Ann. § 16-3-20
     11 is unconstitutional because it automatically
    precludes jury sentencing following a guilty plea in violation of the Sixth,
    Eighth, and Fourteenth Amendments as addressed in Ring v. Arizona, 
    536 U.S. 584
     (2002). Though PCR counsel acknowledged that South Carolina
    state courts had rejected this argument, see State v. Downs, 
    604 S.E.2d 377
     (S.C. 2004), they nevertheless maintained it had not been reviewed
    by federal courts and that trial counsel were thus ineffective in failing to
    adequately preserve the record for subsequent litigation.
    11
    South Carolina Code § 16-3-20(B) provides:
    If trial by jury has been waived by the defendant and the State, or if the
    defendant pleaded guilty, the sentencing proceeding must be conducted
    before the judge. In the sentencing proceeding, the jury or judge shall hear
    additional evidence in extenuation, mitigation, or aggravation of the
    punishment.
    27
    The PCR court scheduled an evidentiary hearing during which it “had the opportunity to
    view and hear the witnesses who testified in person, and make a credibility assessment with
    regard to each witness.” J.A. 7524.
    1. Mahdi’s PCR Evidence
    PCR counsel’s presentation focused on the Mitigation Evidence claim. Specifically,
    they argued that trial counsel “presented . . . short[,] brief[, and] cursory testimony from
    Ms. Hammock,” J.A. 2212, which conveyed “the basics of the story . . . with a very broad
    brush,” but omitted crucial details. J.A. 2213–14. PCR counsel promised “to show the
    humanity” in Mahdi that the trial court could not find. J.A. 2213. In doing so, they called
    members of Mahdi’s family, non-family lay witnesses, and mental health experts.
    a. Mahdi’s Family Members
    Four members of Mahdi’s extended family—one uncle and three aunts—testified
    on his behalf. None of his immediate family members—Shareef, Vera, or Saleem—were
    present at the evidentiary hearing or submitted affidavits to the PCR court. We first
    summarize the testimony from Carson and Lawanda before turning to Mahdi’s maternal
    aunts, Rose Gupton (“Rose”) and Sophia Gee (“Sophia”).
    i. Carson and Lawanda
    Carson began by recounting the role that race played in Mahdi’s paternal family,
    the Burwells. He described Shareef’s enrollment in a predominantly White school in
    Lawrenceville as “a fairly terrible experience,” which resulted in him becoming angrier, “a
    lot more uncontrollable, a lot more despondent,” and hostile towards White people. J.A.
    28
    2229–30. Carson also remembered his mother, Nancy, as someone obsessed with race who
    was constantly trying to “pass[]” as White. 12 J.A. 2232.
    According to Carson, Shareef was the only one of his siblings who did not graduate
    from high school or attend college. Instead, he enlisted in the U.S. Marines. Carson testified
    that “something happened to him [during his service]. He had a discharge and . . . [i]t was
    not good. . . . [I]t made him a more radical person, [an] angry person[.]” J.A. 2235.
    Turning to Mahdi’s childhood, Carson testified that Vera “wasn’t cruel, but she just
    wasn’t doting.” J.A. 2240. In contrast, Shareef was “very affectionate, very concerned,
    very much concerned. . . . [H]e was always doting on his sons and always very, very
    affectionate with them.” J.A. 2240. “He certainly tried to . . . show favoritism to [Mahdi]
    as much as he could[.]” J.A. 2240. However, according to Carson, Shareef was incapable
    of adequately raising his children: “He never had a job to speak of—consistently
    [un]employed . . . They didn’t consistently go to school and he lived in public housing and
    section eight or whatever. No, he couldn’t take care of them.” J.A. 2241. Lawanda agreed,
    suggesting that Shareef’s constant moving was due, in part, to his efforts to “stay under the
    12
    Lawanda described Nancy as someone who “definitely wanted to be more than
    she thought people thought she was.” J.A. 2449. For instance,
    [i]f she went to downtown and interacted with white people, they knew she
    was a light red-headed black woman, but when she left Lawrenceville then it
    depended upon what people thought. If they didn’t think she was black, she
    could be white, and if they did, well, she’d be black.
    J.A. 2450. Lawanda attributed “the family lightness and red hair” to Nancy’s grandfather,
    who “was the product of a relationship between a slave and an [I]rish woman.” J.A. 2496.
    The “woman was sent to Boston with child and the father of the child disappeared, was
    never seen again.” J.A. 2496.
    29
    radar with the . . . educational system” by not drawing too much attention due to the boys’
    mounting absences. J.A. 2464.
    After one visit where Carson found Mahdi and his brother skipping school, “playing
    out in the yard and being destructive, tearing up toys that were left out,” while Shareef was
    “not really noticing what they were doing . . . not saying anything,” J.A. 2243–44, he
    decided to take Mahdi to live with him and Lawanda in Baltimore.
    Carson described that experience as a very difficult period. At one point, he had to
    attend a meeting with Mahdi’s principal because Mahdi made several suicidal statements
    such as, “Well, why doesn’t someone just shoot me?” and “If I had a gun I would just shoot
    myself.” J.A. 2248. Carson testified that Mahdi made similar statements at home as well.
    Despite these threats, Carson concluded Mahdi “didn’t really want to kill himself. . . . He
    was just playing games.” J.A. 2265. Lawanda agreed, testifying that Mahdi would often
    say, “Just shoot me,” J.A. 2467, but she “never thought that he was serious about it,” J.A.
    2468.
    To that end, Carson recounted an incident when he came home and found his wife
    “giving [Mahdi] a whipping,” which he “monitor[ed] to make sure she didn’t go
    overboard.” J.A. 2248. Lawanda testified that she took Mahdi’s belt and spanked him with
    it, though her “purpose was not to really hurt him but to let him know that [she] was in
    charge.” J.A. 2467. Afterwards, Mahdi “put soot on his face, on parts of his body to make
    it look like it was bruised and some ketchup on his face and called 9-1-1 and the police
    came to the door.” J.A. 2248. The officers took Mahdi to the hospital, where he told them,
    “You need to just give me your gun so I can shoot myself,” and they “took him straight to”
    30
    the Carter Center. J.A. 2250. “It took [Carson and Lawanda] two months to get him out of
    there[.]” J.A. 2250. While Mahdi was committed, Lawanda testified that his doctors told
    her that Mahdi was being disruptive, “throwing chairs” and “kicking doors,” and that they
    had to put him in isolation. J.A. 2493.
    Upon his release, the Carter Center recommended Mahdi receive follow-up care
    and counseling. Carson testified that he “sent [Mahdi] to a psychiatrist every Monday” for
    “[t]hree or four months.” J.A. 2252. But, according to Lawanda, Mahdi refused to talk
    during these sessions.
    Carson testified that he did not remember being interviewed by anyone from
    Mahdi’s South Carolina defense team but that he “most definitely” would have testified on
    Mahdi’s “behalf and [told] the family story.” J.A. 2256. Carson further stated that he would
    have asked for mercy because Mahdi “didn’t have a chance in hell” because of “the
    parenting he had, the moving around, the mother abandoning him, all kinds of poverty,
    hunger at times, clothing—lack of. You name it.” J.A. 2257.
    Lawanda remembered speaking with Mahdi’s South Carolina defense team after his
    arrest but said she was not asked to testify. At the PCR evidentiary hearing, when asked in
    retrospect if she would have been willing to speak on Mahdi’s behalf, she responded that
    she was “not sure.” J.A. 2477.
    ii. Mahdi’s Maternal Aunts
    Rose testified about Mahdi as a child, describing him as “very angry. He was angry.
    . . . [He threw] cereal bowls across the kitchen floor. He hit [his mother] a couple of times.”
    31
    J.A. 2288. Sophia described Vera as “really protective,” even “over-protective,” of Mahdi
    and his brother. J.A. 2296–97. “She wouldn’t let them play.” J.A. 2297.
    That said, according to Rose and Sophia, the only reason Vera left her sons under
    Shareef’s care when she fled the relationship was “[b]ecause he threatened to kill her if she
    took them and he meant it, too.” J.A. 2288, 2298. After Vera left, Shareef “wouldn’t let her
    see [the boys] or speak to them, but . . . she used to send them toys and clothes.” J.A. 2298.
    Sophia testified that Shareef “was abusive; that he used to beat [Vera] and he was
    controlling.” J.A. 2298. She recounted a time when Vera came to her house “covered in
    bruises from head to toe and she said Shareef beat her up. She was trying to see the children
    and he beat her up.” J.A. 2299. Years later, when Mahdi was around sixteen or seventeen,
    Sophia tried to reunite him with his mother. She testified that, at the time, neither Mahdi
    nor his brother knew she was alive. “[A]t first [the reunion went well] but then after a while
    . . . it went bad.” J.A. 2301. Mahdi “slashed her tires” because Vera “wouldn’t let him use
    the car.” J.A. 2306–07.
    Rose said she did not speak with anyone from Mahdi’s South Carolina defense team
    before his trial. Indeed, she claims to have not even been aware that he had been arrested
    for capital murder until her sister told her he had already been convicted. In contrast, Sophia
    testified that she, along with her sister Corliss spoke with the South Carolina defense team
    32
    for around an hour. 13 Both Rose and Sophia stated they would have testified on Mahdi’s
    behalf during his sentencing hearing had they been asked. 14
    b. Non-Family Lay Witnesses
    PCR counsel also called several lay witnesses from Mahdi’s childhood. Myra
    Harris, Mahdi’s third-grade teacher from Baltimore, testified that he was prone to outbursts
    and came to her class with significant gaps in his education. According to Harris,
    “sometimes the anger would get to a level where . . . he would have to go into a time out.”
    J.A. 2325. Other times he refused to do work. And on one occasion, Mahdi ran “out of the
    classroom,” out of the building, “and ha[d] to be retrieved.” J.A. 2326. Nevertheless, his
    behavior improved during his time in her class after he and Harris developed a relationship.
    Carol Wilson, Mahdi’s fifth-grade teacher from Brunswick County, presented a
    similar narrative. She testified that Mahdi was referred to the child study team as a
    candidate for special education based on his behavioral deficiencies. Wilson observed that
    Mahdi’s marks on the Burks Rating Scale—which tests behavior—demonstrated “very
    significant and excessive self-blame, poor impulse control, and excessive resistance. He
    ha[d] also exhibited periods of extreme sadness at times.” J.A. 2335. Wilson concluded
    Mahdi was “unable to cope with these feelings,” making “him unable to function and
    13
    Rose testified that she spoke with Sophia and Corliss “every day” and did not
    believe either was aware of Mahdi’s trial. J.A. 2291.
    14
    PCR counsel also submitted an affidavit from Mahdi’s paternal aunt, Sandra
    Wynn Burwell (“Sandra”)—Nathan’s ex-wife—much of which was devoted to the Burwell
    men’s ineptitude in supporting their families. Sandra also addressed Shareef’s volatile
    relationship with Vera, including his attempt “to kill [her] with their sons watching.” J.A.
    2931.
    33
    effectively learn in school.” J.A. 2335–36. That said, the child study team, which she
    chaired, determined he “had a full scale IQ of 118,” and Wilson considered him “an
    intelligent kid.” J.A. 2337.
    Wilson’s team later had a meeting to discuss Mahdi’s eligibility for special
    education, which Shareef attended. According to Wilson, when the team’s psychologist
    presented his findings, Shareef “became very angry . . . and he got up and he cursed us and
    he left,” saying “that he didn’t want any white man writing negative reports about his son.”
    J.A. 2333. Ultimately, the team determined Mahdi was “eligible for the emotionally
    disabled program with recommended assistance in the area of reading.” J.A. 2341. They
    also recommended that he receive counseling.
    Eventually, Shareef allowed Mahdi to join Wilson’s class, albeit briefly. She
    described Mahdi as “depressed and . . . very sad,” but “never disrespectful.” J.A. 2344. But
    “it came [to] a point of time that [she] had to sit him next to [her] in order for him to get
    his work done.” J.A. 2344. Mahdi liked to draw, but Wilson testified “he would use ink
    and draw pictures of people hanging, the nooses and things like that.” J.A. 2345. Mahdi
    did not finish the school year due to Shareef’s decision to homeschool the boys. After that,
    Wilson said Mahdi “got lost in the cracks.” J.A. 2348. Neither Harris nor Wilson spoke
    with Mahdi’s South Carolina defense team, but both stated they would have testified on
    his behalf at sentencing. Both teachers conceded that they had no knowledge about Mahdi’s
    home life.
    George Smith also testified at the PCR hearing. Smith was well-known and
    respected in the local Black community for having successfully sued Brunswick County
    34
    under the Voting Rights Act. According to Smith, Shareef admired him “for taking on these
    white people and winning because . . . he didn’t particularly like white people. . . . [H]e
    just hated them with a passion.” J.A. 2371–72. Smith recalled an incident when Shareef
    jumped into the local White swimming pool and refused to leave. According to Smith,
    Shareef “was in the pool swimming around and cursing, using extremely vile language . . .
    and hollering as loud as he possibly could as to try to inflame these policemen that were
    standing around.” J.A. 2374–75. The police called Smith and asked him to help resolve the
    issue. Eventually, Shareef agreed to leave the pool so long as Smith would accompany him
    to the jail. Smith testified that when they arrived at the cell, Shareef “just went wild. He
    took the furniture and started throwing the chairs against the wall . . . . [I]t was just as
    violent as anything [Smith] ha[d] ever seen in [his] life.” J.A. 2377.
    Smith also testified about Mahdi’s court hearing following the standoff at his
    grandmother’s house. Smith recalled that the judge described Mahdi as a “smart” and
    “nice-looking kid” and recognized that “[h]is problem [was] his father.” J.A. 2379. Had
    anyone from Mahdi’s South Carolina defense team contacted him, Smith said he would
    have testified and “probably would have” asked the trial court to show mercy. J.A. 2378. 15
    15
    Sharon Pond, a mental health therapist from Lawrenceville also testified on
    Mahdi’s behalf, though she had never met him before the evidentiary hearing. She testified
    about Shareef’s treatment for various mental illnesses, but acknowledged that when
    Shareef was referred to the state hospital after the pool incident, the doctors there did not
    find any indication of major mental illness. Pond was not contacted by Mahdi’s South
    Carolina defense team.
    In addition to the witnesses who testified at the hearing, PCR counsel introduced
    affidavits from Dora Wynn, Douglas Pond, and Sheriff Woodley. Wynn, Mahdi’s
    kindergarten teacher and elementary school principal, stated that he “often simply refused

    35
    c. Mental Health Experts
    PCR counsel called mental health experts to testify as well, including: Dr. Nicholas
    Cooper-Lewter, a licensed social worker; Dr. Craig Haney, a social psychologist; Dr.
    DeRosset Myers, Jr., a clinical psychologist; and Dr. Donna Schwartz-Watts, a psychiatrist.
    Collectively, they testified about the impact various events in Mahdi’s life had on his
    mental health and diagnoses.
    Dr. Cooper-Lewter spoke about incidents where Mahdi witnessed Shareef beating
    Vera and Nancy, which “sen[t] a very, very unhealthy message about how you solve life’s
    problem and how you [relate to] others.” J.A. 2403. To that end, Shareef told Dr. Cooper-
    Lewter that he “wanted [Mahdi] to be [his] warrior. [Shareef] said [Mahdi] was fearless.
    He would do things that [Shareef] was afraid to do.” J.A. 2429. “They practiced shooting
    and using knives and moving about in the countryside as if there was an enemy and how
    to do his work, refused to eat, and would just walk away from school.” J.A. 2922. But she
    “never could figure out why he was so angry” because she “was not aware of other
    circumstances in his home and life” beyond his mother’s absence. J.A. 2922.
    Douglas Pond, Lawrenceville’s Mayor and former Chief of Police, relayed the
    incident when Shareef jumped in the Whites-only pool and refused to leave. Sharon Pond
    testified that Shareef was involuntarily committed after this incident based on an
    emergency worker’s conclusion that he suffered from a mental illness and was imminently
    dangerous to himself or others.
    Sheriff Woodley recalled an incident when Nancy “showed [him] bruises on her
    legs and thighs and told [him] that [Shareef] had beaten her with the buckle end of a belt
    while his sons, Saleem and Mikal, [were] watching.” J.A. 2925. Ultimately, though, she
    refused to testify or press charges. Sheriff Woodley also recounted an incident when
    Shareef “kidnaped [sic] and beat[] his wife after she left him,” which the boys witnessed.
    J.A. 2926. In another incident, Shareef “threw a brick at his sister Kathy through the door
    of the house” and on another occasion “damaged his sister Loretta’s car and put a cinder
    block through her car windows.” J.A. 2926.
    Regarding the standoff, Sheriff Woodley stated that Shareef initiated the disturbance
    because he “had no respect for authority.” J.A. 2927.
    36
    you could distract people and to do whatever you feel you need to do to the enemy. They
    were being taught that regularly on a daily basis.” J.A. 2429. Dr. Myers testified that he
    was “struck by the fact that there seemed to have been a good deal of violence in his family
    of origin” as well as “the fact that there seemed to be a lot of psychopathology there.” J.A.
    2621–22. Dr. Cooper-Lewter acknowledged, however, that there was no evidence that
    Mahdi was physically or sexually abused by his father or any other figure in his life.
    Regarding Mahdi’s suicidal ideations as a child, Dr. Cooper-Lewter referred to an
    incident where Mahdi “attempt[ed] to kill himself by jumping off of a bridge,” J.A. 2411,
    as well as his diagnosis at the Carter Center with major depression recurrent with suicidal
    ideation and severe attachment disorder. Nevertheless, Mahdi’s records indicated to Dr.
    Cooper-Lewter that he “only want[ed] to hurt [him]self when [he could not] have [his]
    way.” J.A. 2528. Dr. Haney agreed that there were clear instances when Mahdi expressed
    suicidality for purposes of manipulation.
    Further, Dr. Haney testified that Mahdi’s “social history became an institutional
    history at age 14,” after which he “was institutionalized for approximately eight and a half
    out of every 10 days of his life . . . in juvenile facilities and adult prison facilities.” J.A.
    2570. And Mahdi’s records are “replete with . . . impulsive acting out.” J.A. 2574. During
    Mahdi’s time in the DJJ, he was diagnosed with conduct disorder, which “means that you
    . . . act in ways that are unacceptable, maybe even harmful. In other words, you don’t
    behave properly” and typically do not show remorse. J.A. 2435. At one point, the DJJ had
    to ban Mahdi from participating in an anger control group, citing an incident where he
    became “very upset and continually threatened that if he [did] not get released from DJJ
    37
    on 9/23/99 he [was] going to fuck people up and go around acting crazy.” J.A. 2523. In a
    separate report, Mahdi stated that if he was not released on time, the DJJ would find him
    hanging in his cell. They later found him “with a sheet tied around his neck sitting in his
    cell and they put him on suicide watch.” J.A. 2524. Mahdi “reported that he did not really
    intend to harm himself. He just wanted to go to special housing because he believed he
    could receive more recreation time there.” J.A. 2525.
    Dr. Cooper-Lewter testified that when Mahdi returned to the DJJ after the standoff,
    his personality assessment revealed a “dysphoric emotionally immature adolescent with a
    conduct disorder.” J.A. 2501–02. “He operated in a . . . way as if he was emotionally
    isolated and mistrustful of the world around him.” J.A. 2504. This culminated in “suicidal
    ideation or suicidal threats and gestures,” including an instance when he tried to electrocute
    himself in his cell. J.A. 2504. Mahdi also “began to act out in destructive ways.” J.A. 2506.
    Soon after he was released from the DJJ, Mahdi went back into custody after his
    conviction for stabbing Rivera. Dr. Haney 16 testified that upon entering custody, a VDOC
    psychologist diagnosed Mahdi “with intermittent explosive disorder and antisocial
    personality disorder.” 17 J.A. 2596. Dr. Myers agreed this was “a justifiable diagnosis at the
    16
    Significantly, Dr. Haney cabined his assessment of Mahdi to “what [he] believe[d]
    that institutionalization did to [Mahdi],” not whether “it had anything to do with the
    commission of these crimes.” J.A. 2604. Dr. Haney knew nothing of the specific facts of
    Captain Myers’ murder and could not testify as to any connection between Mahdi’s time
    in jail and his crimes “because [Dr. Haney did not] know the specifics of those events.”
    J.A. 2605.
    17
    Antisocial personality disorder is “a pattern of behavior in which a person
    disregards the rights of other people, feels entitled to have whatever he wants to, [and] is
    typically associated with criminal behavior but not necessarily.” J.A. 2657.
    38
    time.” J.A. 2657. Mahdi was sent to Wallens Ridge, an adult super-max facility in Virginia,
    which Dr. Cooper-Lewter described as an “environment where racial epithets were spoken
    to the correctional officers, where people were tasered. [Mahdi] was. He speaks of at least
    14 or 15 times that he was tasered.” J.A. 2510. However, Dr. Cooper-Lewter acknowledged
    that Mahdi’s VDOC records did not reflect any such incidents.
    Dr. Schwartz-Watts conducted an independent psychological assessment of Mahdi
    for purposes of the PCR evidentiary hearing. She diagnosed him with major depression
    recurrent with psychotic features and remission, reactive attachment disorder of childhood
    inhibited type, anxiety disorder, paranoid personality disorder, and antisocial personality
    disorder. She also testified that “he [was] suffering these same diagnoses” when he
    committed the underlying offenses, J.A. 2669, though she later conceded that “on that day
    he may not have been depressed at all,” J.A. 2694. Dr. Schwartz-Watts further clarified
    that Mahdi
    did not kill this officer because of PTSD. He did not kill Officer Myers
    because of his depression. He wasn’t irritable. He was at a point in my
    opinion [that] it’s a robbery gone bad. He is at a place. He gets surprised and
    he kills a person. So, [the diagnoses are] present but in terms of like having
    a statutory mitigator that they diminished his capacity, I don’t see that.
    J.A. 2676.
    Further, Dr. Schwartz-Watts testified that Mahdi told her “that he was not really
    suicidal,” “denie[d] that he’s ever been depressed,” “denied that he asked police to kill
    him,” and “repeatedly stated [during his time] in super-max that there is nothing wrong
    with him.” J.A. 2691. She also believed Mahdi “is very intelligent . . . above average in
    intelligence and very perceptive.” J.A. 2693.
    39
    2. The State’s PCR Evidence
    The State called seven members of Mahdi’s South Carolina defense team: (1)
    private investigator James Gordon, Jr.; (2) mitigation investigator Paige Haas; (3)
    psychiatrist Dr. Thomas Martin; (4) forensic psychologist Dr. Geoffrey McKee; (5)
    attorney Carl B. Grant; (6) lead trial counsel Walters; and (7) second-chair trial counsel
    Koger. 18
    a. The Mitigation Investigation Team
    Gordon and Haas (collectively, the “Mitigation Investigation Team”) testified about
    their efforts to compile evidence for the sentencing portion of Mahdi’s trial. Gordon helped
    the South Carolina defense team locate members of Mahdi’s family and also participated
    in team meetings. The State asked Gordon about a memorandum from one of those
    meetings, which included a note from Mahdi’s North Carolina mitigation investigator 19
    stating that Carson “classified Mahdi as a demon because of all the . . . trouble that he [got]
    into” and “indicate[d] that there was conflict in their home.” J.A. 2706; accord J.A. 6642
    (admitted copy of the memorandum, stating “[Mahdi’s] uncle thought he was a demon and
    conflicts did occur”). 20
    18
    The only team members not called were Aiken and Hammock—both of whom
    testified at the sentencing hearing—as well as Don Grindt, a retired South Carolina Law
    Enforcement Division agent hired as a crime-scene investigator.
    19
    Mahdi was indicted for Boggs’ murder and was represented by an independent
    North Carolina defense team.
    20
    When asked at the PCR hearing if he called Mahdi a “demon,” Carson claimed
    he had no memory of doing so but conceded, “Yea, given his behavior I guess I could have
    said it.” J.A. 2272.
    40
    Haas had an active role interviewing potential witnesses. 21 She began her work by
    meeting with Mahdi, who relayed his background and family history. Haas also submitted
    requests to each school Mahdi attended, hospitals (specifically seeking his psychiatric
    records), and correction facilities (including DJJ, VDOC, and SCDC). She testified that
    she went to the schools that Mahdi had attended and spoke with teachers from
    Lawrenceville and Baltimore. Haas said that, though there were “[s]ome nice teachers that
    remember[ed] him,” she did not speak with anyone “that spent lots and lots of time with
    him while he was there.” J.A. 2787.
    As part of her efforts, Haas created a psychiatric chronology for Mahdi. She also
    traveled to Lawrenceville, Baltimore, and Philadelphia to meet with Mahdi’s family
    members, once by herself and another time with Hammock. During these visits, Haas met
    with Nancy, Nathan, Vera, Shareef, and Carson.
    Haas believed Nancy “potentially” could have been a good witness, but testified
    that Nathan was not “helpful at all.” J.A. 2777. As for Vera, Haas described her difficulty
    in establishing a basic rapport with her and her shortcomings as a potential witness:
    The first time I was supposed to be able to talk to her and was unable to
    because she wouldn’t come out of her house. The second time she had agreed
    to see us but when we got there she said that she was sorry but she had to
    wash her hair and would not be able to come outside or talk to us—did speak
    by phone like from the inside of the house to us like on the speaker phone on
    the cellphone. So we did talk to her by phone outside of her house—you
    know, her inside of her house and us outside of the house.
    J.A. 2768–69.
    21
    Haas estimated she had served as a mitigation investigator in approximately thirty
    to forty capital cases.
    41
    Regarding her conversation with Shareef, Haas said that she did not “know what
    kind of witness he would have been,” given that they “spen[t] a lot of time . . . talking a lot
    about his . . . personal beliefs.” J.A. 2773. And Haas relayed that when she asked Carson
    about the incident that led to Mahdi’s involuntary commitment, he said he “still laughs
    about th[at] today because he feels [Mahdi] was just being manipulative and really wasn’t
    struggling [with suicidality].” J.A. 2774.
    Haas also met with Mahdi’s North Carolina attorney, Mark Rabil, and mitigation
    investigator, Janet Holahan. Haas testified that she would have relayed any information
    “dealing with [any] of the potential witnesses in the case” that she received from Holahan
    to Mahdi’s South Carolina defense team. J.A. 2776.
    b. Mahdi’s Mental Health Experts
    The State called Dr. Martin and Dr. McKee, Mahdi’s mental health experts hired by
    his South Carolina defense team. Both provided a similar account of Mahdi’s reason for
    leaving Virginia for North Carolina at the beginning of his crime spree. According to Dr.
    Martin, it had “something to do with a murder” and he wanted to “avoid homicide
    detectives” in Virginia. J.A. 2714. Mahdi told Dr. Martin “that he had murdered . . . in a
    bad drug deal another individual which he thought had not been discovered—at least that
    he was perhaps a suspect . . . because he said it was unreported.” J.A. 2715.
    Mahdi told Dr. McKee a similar story, stating that he “felt that his life was in danger
    . . . because of a rumor that he . . . had killed this other guy’s cousin.” J.A. 2751. Mahdi
    also told Dr. McKee
    that he and this other person were going to force another person to make meth
    42
    and . . . that this other person went to rob this person who shot back and . . .
    that he was just there and not the trigger man, but the man got killed and so
    apparently there was some sort of homicide that he was at least present for.
    J.A. 2751. 22
    Turning to their professional assessments, Dr. Martin determined that Mahdi “had
    a behavioral problem that led to a lot of failed relationships, interactions that were hostile[,]
    aggressive, sometimes quite violent in nature, and that he had some depressive issues that
    were . . . subsequently recurrent due to failure to integrate into society.” J.A. 2717. Mahdi
    was “a loner” who “was essentially becoming a racist militant in his own way.” J.A. 2717.
    “His outlook on life was quite violent. His way of surviving [was] by force. He seemed to
    have no difficulty talking about killing people if necessary in order to achieve
    independence.” J.A. 2717. Dr. Martin also found Mahdi “didn’t seem to have remorse
    about any of the circumstances that were violent in his past.” J.A. 2718. Regarding Mahdi’s
    “recurrent suicidal threats,” Dr. Martin found he was “very manipulative,” citing Carson’s
    statements that “he [did] this all the time to get his way.” J.A. 2718.
    Ultimately, Dr. Martin diagnosed Mahdi with antisocial personality disorder and
    determined he did not “appear to be acting under any influence of any depression at the
    22
    At the PCR hearing, Mahdi’s counsel who represented him before the trial court
    conveyed a similar version of this story. Grant testified that Mahdi “was running from an
    incident that occurred [in Virginia] where he was involved in supposedly in somebody
    being killed or stabbed.” J.A. 2793. Mahdi told Walters that “he was with some other
    individuals and he wanted to create an artificial drought” by “kill[ing] a number of drug
    dealers” so that “everyone would have to buy drugs from Mr. Mahdi and his associates.”
    J.A. 2805. According to Walters, “in the process of creating that artificial drought there
    was an individual that was killed and as a result of that there was an investigation that was
    going on and in addition to that there were other skirmishes that were going on.” J.A. 2805.
    43
    time” of Captain Myers’ murder. J.A. 2719. Mahdi “described very clearly to [Dr. Martin]
    what he was feeling and what he was perceiving during this event. There was no talk of
    feeling depressed, psychotic.” J.A. 2720. Rather, Mahdi said he “was justified,” stating,
    “Great leaders or mass murderers, people only understand force.” J.A. 2723.
    Dr. McKee administered various tests, including a personality assessment screener;
    the information and orientation questions from the Wechsler Memory Scale, Third Edition;
    and “a device for measuring short-term . . . memory.” J.A. 2752. He also diagnosed Mahdi
    with antisocial personality disorder. Dr. McKee opined that Mahdi was not suffering from
    any other mental illness at the time of Captain Myers’ murder.
    Both Dr. Martin and Dr. McKee relayed their findings and told trial counsel they
    did not believe their testimony would be helpful for Mahdi’s case.
    c. Mahdi’s Counsel
    The State also called the attorneys who represented Mahdi before the trial court. 23
    Grant testified about assembling Mahdi’s South Carolina defense team, 24 upon which he
    greatly relied, “trust[ing] professionals who normally [were] very competent in that
    responsibility,” whom he felt obtained “everything that [they] felt [they] needed.” J.A.
    2794. In describing a motion for a continuance he filed after visiting Mahdi’s North
    Carolina counsel, Grant said that he was “discover[ing] that there was going to be a whole
    lot more information [related to Mahdi’s background and family for mitigation purposes]
    23
    Grant was initially appointed as lead counsel, but later had to withdraw after a
    motorcycle accident. Walters was first appointed as second-chair and became lead counsel
    after Grant’s withdrawal. Koger replaced Walters as second-chair.
    24
    Grant had been involved in one death penalty case prior to representing Mahdi.
    44
    that [they] would need in order to adequately present Mahdi’s case on the case in South
    Carolina.” J.A. 2798. The trial court granted the motion and continued the case from
    January 2006 to November of that year.
    Grant and Walters further testified about the mental health experts they hired to
    evaluate Mahdi. According to Grant, neither Dr. Martin nor Dr. McKee found anything
    “that could have been used in the penalty phase.” J.A. 2792. To the contrary, Grant recalled
    “the things that were presented by Dr. McKee actually could have been irritating as far as
    personality and things that would indicate that maybe we were dealing with . . . somebody
    who would [not] be painted in a good light in front of a jury.” J.A. 2792. Walters provided
    a similar account, testifying that Dr. Martin and Dr. McKee suggested Mahdi was “fine”
    and that there was “no insanity defense here, and there [were] no impairments.” J.A. 2812.
    In response, trial counsel took the position that they could not “keep going down this road
    and [the doctors could not] write this report.” J.A. 2812.
    Walters and Koger also testified about their interviews with potential witnesses from
    Mahdi’s family. Ultimately, Walters concluded that Mahdi’s family members “were
    unwilling to assist” and “were just simply indifferent about him. They didn’t really care.”
    J.A. 2828–30. Specifically, Walters testified:
    [Mahdi’s] father refused to participate or his position was sort of standoffish
    and he didn’t want to be involved.[25] His mother made it clear she wasn’t
    going to be involved because she was going to wash her hair, and as far as
    the other sibling [Saleem] he was serving in the military, and as far as the
    25
    According to Koger, Mahdi told trial counsel he did not want his father to
    participate, and trial counsel agreed “that any type of testimony from his father would not
    be advantageous to Mr. Mahdi’s cause.” J.A. 2895–96.
    45
    close family—the aunts—they made it clear, you know, we’re through with
    this.
    ....
    They seemed as if it was a self-fulfilling prophecy that something bad was
    going to happen to him anyway.
    ....
    My people went in. They did the best they could. They’re experts and they
    are good at what they do. They garnered all of the information they could
    and they attempted to put forth the best defense for Mr. Mahdi.
    ....
    [W]e wanted an individual that would testify favorably for him and . . . [i]n
    our search to determine if someone wanted to help Mr. Mahdi, they were
    standoffish. If you want to find information about someone you start with the
    family and the family can then relate to you to other people and say maybe
    these people can assist you. Their position was it started off bad, something
    bad has happened now, and we knew it was headed this way, and we’re not
    going to jump in an [sic] save him.
    J.A. 2837–39.
    Walters recalled Nathan as someone who “didn’t want to be bothered” and “was
    proud of the fact that he had identified his nephew for the North Carolina authorities.” J.A.
    2814. Koger agreed. When asked if Nathan was cooperative with the mitigation team’s
    efforts, Koger responded, “Not at all.” J.A. 2892.
    Walters described Nancy as “a very proud woman” who “wanted to brag about the
    accomplishments of the family. She did not want to address the issues with regard to her
    grandson and how he got there.” J.A. 2815–16. Walters determined “this testimony [would
    not have been] helpful” if all she planned to do was “brag about the accomplishments and
    46
    the educational ability of all of [her] children” other than Shareef. J.A. 2816. Koger
    provided a similar account, testifying that although Nancy was cooperative, she was not
    helpful:
    She was there every day of the trial, and we talked to her every day after the
    trial. . . . [A]nd we would speak with her . . ., but she consistently wanted to
    talk about clearing the family name and we’re not these type of people and
    things of that nature, and really didn’t get the point[.]
    J.A. 2893.
    Walters testified that he also spoke with Carson and Lawanda by telephone, but
    decided not to call Carson as a witness because
    he laughed after the issue where Mr. Mahdi said he was going to kill himself
    and that he had been abused, and . . . had a sadistic sense of humor about
    each event in this child’s life as if he was malingering, he was a faker. It was
    sort of twisted.
    J.A. 2819, 2820. Further, Lawanda
    had to severely beat [Mahdi] over and over again. It moved from being
    chastising the child and whipping the child to a significant beating every day,
    and, of course, Carson even in the interviews admitted that sometimes he
    would not stop his wife from doing so because he wanted the united front.
    J.A. 2820. “[T]heir position was[,] We’re glad he’s out of our house. We did the good deed.
    No one applauded us for it, and now you want us to get involved in attempting to help him
    in a murder case . . . . [H]e is getting his just desserts.” J.A. 2820.
    Though trial counsel “wanted someone there that would assist Mr. Mahdi in this
    process,” Nancy was the only one who was present for sentencing. J.A. 2821. Again,
    though, “[t]he problem with Nancy was [that] she wanted to explain to a Calhoun County
    jury all of the accolades of the family and how successful they were.” J.A. 2821. But trial
    47
    counsel did not “need testimony coming in to save the family name.” J.A. 2821. They
    needed “testimony that directly deal[t] with Mikal Mahdi.” J.A. 2821.
    Trial counsel decided Hammock was their best option to present Mahdi’s family
    history and articulate the issues that occurred in his life, in part, because this would allow
    them to limit the amount of negative evidence that would have otherwise come in had they
    called any lay witnesses. The “bigger problem,” according to Walters, was the fact that
    there was a videotape of Mahdi killing Boggs. 26 J.A. 2826. “So [trial counsel] could [have]
    [m]arch[ed] in 100 family members. . . , [but they] knew this was a disk sitting in
    everybody’s file that would show an execution-style murder . . . that occurred.” J.A. 2826.
    Thus, it was imperative to curb any additional evidence that would have undermined their
    mitigation strategy.
    Finally, when asked why trial counsel did not challenge the constitutionality of
    judicial sentencing under 
    S.C. Code Ann. § 16-3-20
    , Walters responded,
    [W]e wanted [the trial court] to sentence him and the reason was sitting
    judges that have practiced law for an extensive period of time and are also
    involved in the prosecution and defense of criminal cases they are
    desensitized and sort of immune when they hear—not to say anything
    disparaging, but they’ve seen plenty of murder cases over and over and over
    again as opposed to a lay person that may see this film. If you’ve handled
    murder case after murder case after murder case, you can focus on the issues.
    You can take in the significance of the murder itself and the other factors and
    make a rational decision.
    J.A. 2883–84.
    26
    As noted earlier, the tape was admitted into evidence during the sentencing
    hearing over Mahdi’s objection.
    48
    F. The PCR Court’s Ruling and Appeals
    After deliberating, the PCR court entered an exhaustive opinion denying each of
    Mahdi’s IAC claims. In so doing, it set out the proper standard for reviewing claims under
    Strickland and its progeny, and framed its analysis around the Supreme Court’s controlling
    precedent. This is the opinion we review here, so a detailed summary of that court’s
    findings and conclusions follows.
    1. The Jury Sentencing Claim
    The PCR court found “no merit” to Mahdi’s Jury Sentencing Claim because he
    failed to “specify the jury sentencing advantages to which he allude[d], []or how counsel
    inadequately advised him of those advantages.” J.A. 7528. At bottom, Mahdi “did not
    testify, and offered no testimony or other evidence at the merits hearing on this issue.” J.A.
    7528. Nor did he “question any of his former appointed attorneys” about it. J.A. 7528. As
    a result, the PCR court determined Mahdi “failed to meet his burden of proof,” J.A. 7528,
    resulting in both his waiver and abandonment of this claim.
    Nevertheless, the PCR court concluded in the alternative that the record established
    “Mahdi was fully advised of his rights to jury sentencing and the pros and cons of having
    a jury conduct his sentencing verses [sic] a judge determining his sentence.” J.A. 7529.
    Between representations from trial counsel about how they advised Mahdi on this issue
    and statements from the trial court, the PCR court found that “Mahdi clearly understood
    his right to have a jury determine his sentence.” J.A. 7529. And Mahdi “offered no
    testimony on this issue and offered no evidence that contradicted counsel’s sworn
    testimony on this issue” at the PCR evidentiary hearing. J.A. 7530. The PCR court found
    49
    “counsel’s testimony on this issue to be credible” and “supported and corroborated by
    Mahdi’s responses to [the trial court’s] questions during the guilty plea itself.” J.A. 7530.
    According to the court, “[t]here [was] no proof that [trial] counsel was deficient in
    any manner in this regard.” J.A. 7531. But even if they were, the PCR court held that Mahdi
    could not prove prejudice because there was no “reasonable probability he would not have
    pled guilty, and would have proceeded to trial with a different outcome,” in light of the
    “record, including counsel’s credible testimony, the record of the plea proceeding, and the
    evidence that would have been submitted to the chosen jury, including the horrendous facts
    of Myers’s murder, the murder of Christopher Boggs in North Carolina, and Mahdi’s
    maladaptive prison behavior and atrocious criminal record,” J.A. 7531.
    2. The Mitigation Evidence Claim
    The PCR court bifurcated its analysis of the Mitigation Evidence Claim into
    Strickland’s familiar two-pronged approach. First, it considered whether trial counsel were
    deficient in their representation of Mahdi. Though the PCR court found “no merit to these
    allegations,” J.A. 7532, it nevertheless proceeded to the second prong of the analysis and
    considered whether Mahdi would have been prejudiced had counsel’s performance been
    deficient.
    a. Deficient Performance Prong
    In the Mitigation Evidence Claim, Mahdi asserted trial counsel were deficient by:
    (1) failing to call several of Mahdi’s extended family members and community members;
    (2) presenting testimony through Hammock as opposed to Dr. Cooper-Lewter; (3) failing
    to introduce testimony from an expert like Dr. Haney concerning the effect of Mahdi’s life
    50
    of incarceration; (4) failing to adequately investigate, develop, and present evidence of
    Mahdi’s mental health history; and (5) failing to introduce various records at the sentencing
    hearing. The PCR court rejected each of these subclaims on their merits. As discussed
    below, Mahdi procedurally defaulted all but one aspect of the first subclaim (non-family
    lay witnesses) because he failed to appeal the dismissal of all the remaining subclaims (2
    through 5 above) to the Supreme Court of South Carolina. Therefore, we focus our
    attention on that portion of the PCR Court’s analysis denying Mahdi’s first subclaim that
    trial counsel provided ineffective assistance by failing to call non-family lay witnesses
    during his sentencing hearing.
    The court concluded that “[t]he record supports counsel in this case conducted a
    reasonable and thorough mitigation investigation and presented what mitigation they could
    that was favorable to Mahdi at the time of the sentencing proceeding.” J.A. 7556.
    According to the PCR court, counsel’s performance could not have been deficient because
    “much, if not all, of the evidence Mahdi offered at PCR regarding his family and social
    history, whether through family or community witnesses, was cumulative to the evidence
    presented in Mahdi’s capital sentencing proceeding” through Hammock’s testimony and
    exhibits. J.A. 7560.
    In addition, the PCR court cited the “credible evidence at the merits hearing
    show[ing] counsel retained a qualified mitigation investigator,” Haas, who “went to the
    schools Mahdi attended,” “spoke with teachers” who were familiar with him, and compiled
    a summary of his school records, which were introduced at the sentencing hearing. J.A.
    7600–01. The PCR court also cited Hammock’s testimony about Mahdi’s difficulties in
    51
    school, frequent moves, and educational gaps before concluding that trial counsel
    “conducted a reasonable investigation of Mahdi’s school history and presented the same”
    to the trial court. J.A. 7602.
    b. The Prejudice Prong
    After reviewing the “overwhelming,” aggravating evidence presented at the guilty
    plea and sentencing hearings, “along with all the evidence in mitigation Mahdi alleges
    should have been presented”—“along with the aggravating evidence that would have
    almost certainly come in on cross-examination, rebuttal, or contained within the evidence
    itself, and the mitigation evidence presented at the sentencing hearing before [the trial
    court]”—the PCR court found there was “no reasonable probability [the trial court] would
    have returned with a different sentence.” J.A. 7627. Thus, even if trial counsel had been
    deficient, Mahdi had “failed to prove prejudice.” J.A. 7627.
    3. The Judicial Sentencing Claim
    Turning to Mahdi’s final IAC claim, the PCR court dismissed any suggestion that
    trial counsel were ineffective for failing to assert that 
    S.C. Code Ann. § 16-3-20
     is
    unconstitutional. The South Carolina Supreme Court had rejected that exact argument on
    several occasions before Mahdi’s sentencing. “Therefore, counsel could not have been
    deficient in failing to preserve an issue that has no merit under law.” J.A. 7635.
    Moreover, “counsel correctly testified at the PCR hearing” that “Mahdi decided to
    plead guilty because [he] believed he had a better chance of receiving a life sentence from
    [the trial court] than from the jury he had selected.” J.A. 7636. And the PCR court, having
    “had the opportunity to view the witnesses and hear their testimony on this issue,” found
    52
    “trial counsel’s testimony on these issues to be credible.” J.A. 7636. And “Mahdi offered
    no testimony to contradict trial counsel’s testimony on these issues.” J.A. 7636. Thus, the
    PCR court determined that “Mahdi wanted to be sentenced by [the trial court], not the jury
    he had initially selected and [e]mpaneled.” J.A. 7636. And so, “it would have made no
    sense for Mahdi to have objected to the constitutionality of the statute and insist on pleading
    guilty and being sentenced by the jury, and counsel was not ineffective in failing to object
    to the constitutionality of” 
    S.C. Code Ann. § 16-3-20
    . J.A. 7636
    ****
    Represented by separate appellate counsel, Mahdi appealed only one aspect of the
    PCR court’s denial of his Mitigation Evidence Claim:
    Was [Mahdi] denied the effective assistance of counsel at his capital
    sentencing proceeding by trial counsel’s decision to rely entirely on a single
    expert witness to present mitigating evidence about [Mahdi’s] background
    instead of calling available lay witnesses who could have provided detailed
    and specific testimony in mitigation?
    J.A. 7721. In his filings with the South Carolina Supreme Court, Mahdi clarified that he
    was challenging only the PCR court’s ruling “denying his claim that available non-family
    members, i.e., members of the community, including his former teachers, should have been
    called as witnesses.” J.A. 7822. He did not challenge the remainder of the PCR court’s
    decision, including its rejection of the other subclaims from the Mitigation Evidence Claim.
    Both that court and the U.S. Supreme Court denied his appeal.
    G. The Second State-Court PCR Proceedings and Appeals
    Seven years after filing his first PCR application, Mahdi’s federal habeas counsel
    filed a successive one in South Carolina state court. In addition to re-raising the Jury
    53
    Sentencing, Mitigation Evidence, and Judicial Sentencing Claims from his first PCR
    application, Mahdi presented a fourth IAC claim for review:
    • The “Guilty Plea” Claim: Trial counsel rendered ineffective assistance
    because they “advised [Mahdi] that the guilty plea would be considered
    as mitigation.” J.A. 8181.
    The State moved to dismiss. The PCR court granted the motion and entered an order
    denying Mahdi’s application because: (1) it was time barred under the one-year South
    Carolina statute of limitations for PCR actions, 
    S.C. Code Ann. § 17-27-45
    ; (2) it was
    improperly successive, 
    S.C. Code Ann. § 17-27-90
     (the Supreme Court of South Carolina
    will refuse to consider claims raised in a second appeal that could have been raised at an
    earlier time); S.C. App. Ct. R. 203(d)(3), 243 (if a prisoner has failed to file a direct appeal
    or a PCR application and the deadlines for filing have passed, he is barred from proceeding
    in state court); (3) the State was entitled to judgment as a matter of law based on the
    pleadings; and (4) the State was entitled to judgment as a matter of law because there was
    no genuine issue of material fact. Mahdi appealed to the South Carolina and the U.S.
    Supreme Courts. Both denied his petitions.
    H. Mahdi’s Emergency Motion in the District Court for Supplemental Expert Funding
    After filing a placeholder § 2254 petition, Mahdi’s federal habeas counsel submitted
    an ex parte emergency motion in the district court to amend the expert witness budget,
    noting that they had “recently discovered evidence related to race-based trauma that
    [Mahdi] experienced during his childhood that . . . warrant[ed] presentation” as a claim
    under Martinez v. Ryan, 
    566 U.S. 1
     (2012). J.A. 11. Counsel indicated they had contacted
    Dr. Hope Hill, a Professor at Howard University, who agreed to develop and present this
    54
    evidence. The motion asked the district court to authorize $22,500 in fees and $2,500 in
    travel expenses for her.
    The following day, the magistrate judge entered an ex parte text order directing
    counsel to provide the following relevant information:
    (1) a brief outline of the “recently discovered evidence” related to race-based
    trauma that [Mahdi] experienced that provides the basis for an additional
    expert witness; [and] (2) a brief summary of how this information impacts
    the claims to be raised by [Mahdi] in the Amended Petition.
    J.A. App. F, ECF No. 69.
    In response to the first query, Mahdi represented that “[t]rial counsel and PCR
    counsel failed to investigate, in detail, [his] genealogy” because, although “counsel very
    generally pieced together family biographies, there was no in-depth examination of Mr.
    Mahdi’s lineage.” J.A. 29. Federal counsel, however, represented that they had “been able
    to explore the history of Mr. Mahdi’s paternal side of the family,” which they discovered
    “descends directly from the relationship between a slave-owner and a slave.” 27 J.A. 29–30.
    According to Mahdi, “[t]his information is critical, particularly in light of [his] mindset
    prior to the crimes at issue in this case.” J.A. 30. And had trial or PCR counsel been aware
    of this “slave lineage,” it should have “led to an examination of the intersection of race and
    trauma.” J.A. 30.
    27
    Mahdi particularly faults his PCR counsel, pointing to a note in a report from Dr.
    Cooper-Lewter that Mahdi was a descendent of a White homeowner’s relationship with
    the family’s Black gardener. Mahdi submits that, “[a]t a minimum, that should have
    warranted a closer investigation of [his] lineage, which would have revealed [his] slave
    lineage and led to an examination of the intersection of race and trauma.” J.A. 30.
    55
    Mahdi pointed to a letter he wrote to Nancy in 2003 expressing “a deep desire and
    yearning to learn about his ancestry, as he believed that helped define who he was as a
    person.” 28 J.A. 30–31. This was important, according to federal habeas counsel, because
    Mahdi
    grew up in a home with conflicting dualities about race: His grandmother
    constantly emphasized the importance of “fitting in” and “passing as white,”
    while his father converted to Islam to shed his “slave name” and repeatedly
    taught [Mahdi] to rebel against “white society” and indoctrinated [him] in
    anti-white and anti-establishment propaganda.
    J.A. 31. Mahdi’s counsel stated that their “aim [was] to continue to explore information
    about Mr. Mahdi’s family history and lineage in order to develop new mitigation themes
    and evidence that ha[d] not been presented.” J.A. 31.
    As for how this information would impact his claims, Mahdi submitted that the new
    evidence could show that race and his family history played some part in his development
    and subsequent criminal acts. Mahdi’s “prior defense teams—both at trial and PCR—did
    not focus or develop any strong evidence or narrative to address the multiple aspects of
    trauma that [he] experienced throughout his life.” J.A. 31. “While some evidence was
    presented in PCR about generalized stressors that Mr. Mahdi experienced, PCR counsel

    The letter stated:
    I have gotten to a point in my life when I start to wonder who my ancestors
    are, trace my roots to see where I come from. I really want to know these
    things . . . Where does the Burwell lineage come from? I want to know these
    things, it’s sad that I don’t know my ancestry. I should know these things.
    This is somewhat of an important issue to me. Please tell me.

    56
    his development and subsequent criminal acts.” J.A. 31. Dr. Hill, according to counsel,
    would be able to examine the “impact of these traumatic events and stress factors on Mr.
    Mahdi in the context of his unique ancestry and extrinsic and intrinsic racial identity,” J.A.
    31, while also analyzing “the additional impact of the repeated racial ‘microaggressions’
    that Mr. Mahdi experienced from his grandmother, father, community, and other family
    members,” J.A. 32, and how they emboldened his survivalist mentality.
    The district court denied the emergency ex parte motion. Noting that “counsel
    want[ed] to present as much beneficial evidence as possible,” the court reiterated its own
    duty to determine “what [was] reasonably necessary for adequate representation” to
    warrant funding under 
    18 U.S.C. § 3599
    (a)(2). J.A. 39. And here, the district court had
    already approved “$20,000 in funding for a mitigation investigator (and an additional
    $2,000 for the mitigation expert’s travel expenses) and $12,500 for a social historian.” J.A.
    40. Mahdi’s federal mitigation investigator, Sam Dworkin, had already “compiled a
    detailed family history, tracing Mr. Mahdi’s family back to English settlers who arrived in
    Virginia in 1648 and set up large plantations.” J.A. 30.
    To that end, the court specifically found Mahdi’s “[c]ounsel ha[d] not set out why
    the issue of trial counsel’s alleged ineffectiveness regarding the failure to present
    mitigation evidence could not be fully developed through the use of the mitigation
    investigator and social historian.” J.A. 40 (citing Wright v. Angelone, 
    151 F.3d 151
    , 163
    (4th Cir. 1998) (“[A]n expert should be appointed when a substantial question exists over
    an issue requiring expert testimony for its resolution and the defendant’s position cannot
    be fully developed without professional assistance.”)). “While counsel may find it
    57
    preferable to present this claim through a psychologist with a specialty in race-based
    trauma, the court [found] such an expert unnecessary to fully develop the claim of
    ineffective assistance of counsel in regard to mitigation evidence.” J.A. 40.
    Mahdi moved to alter or amend, claiming the standard used by the district court was
    more demanding than the one announced by the Supreme Court’s intervening decision in
    Ayestas v. Davis, 
    138 S. Ct. 1080
     (2018). According to Mahdi, “Ayestas required [the
    district court] to [have] provide[d] [him] with necessary resources so he would have [had]
    a fair opportunity to show why [it] should [have] excuse[d] the procedural bars” as to his
    claim. J.A. 555.
    The district court denied the motion and explained that it had “recited the applicable
    standard [for funding requests] and focused on whether the requested services were
    reasonably necessary to adequately represent Mahdi.” J.A. 911. After summarizing the
    Ayestas decision—which was decided a year after Mahdi’s emergency ex parte motion was
    denied—the district court rejected Mahdi’s contention that it “ha[d] an obligation to
    authorize funding for experts where a mitigation investigator ha[d] identified a need for
    expert assistance” as being “directly contradicted by Ayestas’s emphasis on the district
    courts’ broad discretion in assessing funding requests.” J.A. 911. “Counsel’s preferences
    . . . do not equate to a showing that a reasonable attorney would disregard certain services
    as sufficiently important or reasonably necessary.” J.A. 911.
    The district court explained that
    [a] review of Mahdi’s original funding request suggests that counsels’
    mitigation investigator had already gathered all of the pertinent factual
    information counsel planned to allege [that] trial and PCR counsel should
    58
    have presented and that counsel had already formed reasoned arguments as
    to why that information was critical to Mahdi’s mitigation presentation.
    J.A. 912. “Those arguments included the impact of Mahdi’s lineage and upbringing on his
    own racial identity and how the resulting internal conflict may have affected him.” J.A.
    912. “The court could not discern from counsels’ request what additional value a
    psychological report on this subject would offer and, thus, could not find the requested
    services reasonably necessary.” J.A. 912. Indeed, even in his motion to reconsider, “Mahdi
    broadly assert[ed] the necessity of the psychologist’s services . . . but still fail[ed] to
    articulate specific reasons why the services were warranted.” J.A. 912. Thus, the court
    reaffirmed its decision to deny the motion.
    I. Mahdi’s § 2254 Petition for Habeas Corpus
    1. Mahdi’s Petition
    Mahdi’s § 2254 petition raised the Jury Sentencing, Mitigation Evidence, Judicial
    Sentencing, and Guilty Plea Claims. See Mahdi v. Stirling, No. 8:16-3911, 
    2018 WL 4566565
     (D.S.C. Sept. 24, 2018). 29 The State moved for summary judgment. Mahdi
    attached an affidavit from Dworkin, to his response in opposition. 30 Dworkin suggested
    trial and PCR counsel were ineffective for failing to investigate and present certain
    evidence in five key areas of Mahdi’s life: (1) his history of race-based trauma; (2) alleged
    physical abuse by his father; (3) his father’s mental illness and admissions to instilling
    29
    Mahdi raised other claims as well, which we do not address here. We limit this
    summary to only those claims that received a COA.
    30
    As previously noted, the district court granted Mahdi’s request for $22,000 in
    expert funding to hire Dworkin to conduct his investigation.
    59
    violence in his children; (4) his attempts to get his life back on track during the summer of
    2004; and (5) Nancy’s letters to North Carolina counsel suggesting South Carolina trial
    counsel were not engaging with her.
    Regarding race-based trauma, Dworkin stated that federal habeas counsel’s
    investigation “uncovered that African American lineage resulting in [Mahdi’s] immediate
    family line was the product of slave and slave owner.” J.A. 367. He claimed this lineage
    was relevant because “a core component of mitigation” stems from Mahdi’s “significant
    race-based trauma, . . . including knowing who [he] is, where he comes from, and how the
    experiences of his, and his family’s, past directly form mitigating information.” J.A. 367.
    Concerning allegations of Shareef’s physical abuse, Dworkin cited an interview
    with Nate Burwell, IV (“Nate”), Nathan’s son and Mahdi’s paternal cousin, who “recall[ed]
    [Mahdi] and Saleem being beaten by their father as children, saying that he [Nate] ‘can
    hear them screaming still.’” J.A. 371 (alteration in original). He also remembered “Vera
    needing to abandon her family to avoid the abuse of Shareef.” J.A. 371.
    Turning to Shareef’s mental illness and indoctrination of his sons, Dworkin
    represented that he had interviewed Mahdi’s father and discovered information trial and
    PCR counsel had failed to uncover. Specifically, Dworkin referred to Shareef’s decision to
    change his name and remove Mahdi from formal schooling as “isolating” events. J.A. 369–
    70. Shareef also admitted he was “on a more ‘Jihadist tip’ for a while and imparted those
    radical lessons to his son,” telling Mahdi “that the American Way and society was ‘built
    on killing people and taking shit.’” J.A. 370.
    60
    Regarding the brief period during the summer of 2004 immediately following
    Mahdi’s release from VDOC’s custody, Dworkin posited that he “was engaged in sincere
    efforts to re-enter society.” J.A. 372. These included a desire to return to school to complete
    his GED as well as applying for food stamps. According to Dworkin, “[t]hese are steps one
    does not take if they are truly disengaged from society. . . . These are all solid and concrete
    examples of a young man trying to integrate and take his second chance seriously.” J.A.
    373.
    Finally, Dworkin suggested trial counsel were “disengaged from the Burwell
    family, who wanted to be involved.” J.A. 373. In support, Dworkin cited a 2005 letter
    Nancy wrote to Mahdi’s North Carolina trial counsel, “relay[ing] that there had been no
    communication with South Carolina counsel.” J.A. 374.
    2. The District Court Denies Mahdi’s Petition
    After reviewing the issues and extensive record (including Dworkin’s affidavit), the
    district court entered a thorough opinion granting the State’s motion for summary
    judgment. On the Jury Sentencing Claim, the court determined Mahdi’s assertion that his
    trial counsel were ineffective for failing to adequately advise him of the advantages of jury
    sentencing was directly contradicted by the record. Citing the transcripts from the ex parte
    and guilty plea hearings as well as Walters’ testimony from the PCR evidentiary hearing,
    the district court found “nothing in this evidence to rebut the presumption that trial counsel
    provided effective representation and adequately advised Mahdi so that he could make a
    fully-informed decision to plead guilty.” Mahdi, 
    2018 WL 4566565
    , at *45.
    61
    Addressing the Mitigation Evidence Claim, the district court concluded Mahdi
    preserved only one aspect of it for review under § 2254(d)—whether “trial counsel were
    ineffective in failing to investigate and present mitigating evidence from non-family lay
    witnesses”—because that was the sole issue he raised on appeal from his first state-court
    PCR proceeding. Id. at *15. After providing a detailed summary of the evidence presented
    at sentencing, the trial court’s judgment, and the evidence presented at the PCR merits
    hearing, the district court determined the PCR court had properly applied Strickland and
    its progeny—as well as their South Carolina state law equivalents—in holding that Mahdi
    had not shown trial counsel were deficient. Moreover, the district court found “the PCR
    court’s determination that the PCR evidence was cumulative [was] not unreasonable.
    While the PCR evidence certainly expanded on and added depth to Ms. Hammock’s
    testimony and the other evidence offered at sentencing, it would not have significantly
    altered the sentencing profile presented to the” trial court. Id. at *30.
    The district court determined the remaining aspects of Mahdi’s Mitigation Evidence
    Claim were procedurally barred. In considering Mahdi’s arguments to overcome that bar,
    the court focused its analysis on his assertion that he had established cause and prejudice
    under Martinez. At bottom, Mahdi suggested the district court should excuse his procedural
    default because his PCR counsel were ineffective for failing to investigate the five claims
    Dworkin identified in his affidavit.
    The district court rejected each of Mahdi’s arguments, finding trial and PCR counsel
    had conducted an adequate investigation and, even if they hadn’t, that he was nevertheless
    not prejudiced by any failure by PCR counsel to present this newly discovered information.
    62
    Nor did any of these new points fundamentally alter Mahdi’s claims. The district court
    reasoned that “the evidence in Mr. Dworkin’s affidavit was included, to various degrees,
    in the PCR evidentiary hearing.” Id. at *38. And “even assuming that counsel were
    deficient in all the ways Mahdi alleges, after independently reweighing all of the
    aggravating and mitigating evidence, . . . absent the alleged errors,” the district court
    determined “there is no reasonable probability that [the trial court] would have reached a
    different sentencing decision and the court remains confident in this case’s outcome.” Id.
    at *40. Mahdi therefore had not carried his burden to excuse his procedural default.
    Turning to the Judicial Sentencing Claim, the district court found South Carolina’s
    capital sentencing procedures did not violate Mahdi’s constitutional rights. It summarized
    that “Ring established that when a defendant exercises his right to a jury trial on a capital
    offense, he is entitled to have a jury determine any aggravating factors necessary to impose
    a death sentence.” Id. at *41. But it noted that the Supreme Court of South Carolina had
    distinguished Ring because it “‘did not involve jury-trial waivers and [thus] is not
    implicated when a defendant pleads guilty’ under South Carolina’s death penalty statute.”
    Id. at *42 (quoting Downs, 604 S.E. 2d at 380). Thus, it concluded, “trial counsel were not
    ineffective for failing to raise a meritless claim.” Id. at *43; see also id. at *43 n.40
    (observing that “[i]n the two years prior to Mahdi’s trial, the Supreme Court of South
    Carolina decided three cases expressly finding the death penalty statute constitutional and
    noting Ring was not implicated when a capital defendant pled guilty”). Moreover, the court
    determined that, “[a]long with waiving his right to a jury trial, Mahdi expressly and
    63
    voluntarily waived his right to jury sentencing,” while also “admit[ing] to the facts of the
    crime as stated by the [State].” Id. at *42.
    Finally, regarding the Guilty Plea Claim, the district court found “trial counsel
    [were] not at fault for Mahdi’s alleged misunderstanding that his guilty plea would
    automatically preclude a death sentence.” Id. at *45. It observed that, in fact, the record
    suggests Walters “explicitly informed” Mahdi that “pleading guilty did not guarantee a life
    sentence.” Id. (emphasis added). Moreover, it concluded trial counsel’s advice was not
    incorrect as the trial court expressly incorporated Mahdi’s guilty plea into the penalty phase
    and considered it as part of his sentence. And the trial court, “[which] was in a unique
    position to assess these factors, did not refuse to consider Mahdi’s guilty plea or penalize
    him for the timing” since it occurred one day after he was caught with the handcuff key in
    the courtroom. Id. at *46. In the district court’s view, the trial court “properly assessed how
    the plea, in context, reflected Mahdi’s character and, in particular, his alleged acceptance
    of responsibility. This is exactly the type of individualized consideration required in capital
    sentencing.” Id. (citing Lockett v. Ohio, 
    438 U.S. 586
    , 605 (1978) (“Given that the
    imposition of death by public authority is so profoundly different from all other penalties,
    we cannot avoid the conclusion that an individualized decision is essential in capital
    cases.”)).
    Mahdi filed a timely notice of appeal. This Court has jurisdiction under 
    28 U.S.C. § 1291
     and 
    28 U.S.C. § 2253
    (c)(1)(A).
    64
    II.
    We granted a COA on five issues: (1) whether the district court abused its discretion
    in denying Mahdi’s supplemental expert funding request; (2) the Jury Sentencing Claim;
    (3) the Mitigation Evidence Claim; (4) the Judicial Sentencing Claim; and (5) the Guilty
    Plea Claim. We first address Mahdi’s funding request before considering his IAC claims.
    A. Supplemental Expert Funding Request
    Under 
    18 U.S.C. § 3599
    , district courts “may authorize” expert funding in capital
    cases so long as it is “reasonably necessary for the representation of the [petitioner].” 
    Id.
    § 3599(f); see id. § 3599(a)(2). The Supreme Court has explained that
    [p]roper application of the “reasonably necessary” standard . . . requires
    courts to consider [(1)] the potential merit of the claims that the applicant
    wants to pursue, [(2)] the likelihood that the services will generate useful and
    admissible evidence, and [(3)] the prospect that the applicant will be able to
    clear any procedural hurdles standing in the way.
    Ayestas, 
    138 S. Ct. at 1094
    . Though it may be error for a district court to refuse funding, it
    is only so in “those cases in which funding stands a credible chance of enabling a habeas
    petitioner to overcome the obstacle of procedural default.” 
    Id.
     (emphasis added). To that
    end, the Supreme Court and “Congress ha[ve] made it clear . . . that district courts have
    broad discretion” in this assessment. 
    Id.
     (emphasis added); see also 
    id.
     (noting that by
    using the word “may” in § 3599, Congress “made it perfectly clear that determining
    whether funding is ‘reasonably necessary’ is a decision as to which district courts enjoy
    broad discretion”). Thus, we will reverse a district court’s denial of a funding request only
    if we determine it abused that considerable discretion. This is a heavy burden not easily
    carried.
    65
    Mahdi renews his argument that the district court applied an overly demanding legal
    standard in denying his ex parte emergency motion to amend the expert witness budget to
    facilitate further investigation into a possible mitigation claim related to race-based trauma.
    According to Mahdi, the court improperly relied on our decision in Wright, which he
    alleges is “outdated.” Opening Br. 53. Had the district court “applied the correct standard,
    as dictated by Ayestas,” Mahdi contends, “it would have necessarily found that a
    ‘reasonable attorney would regard the services as sufficiently important.’” Opening Br. 54
    (quoting Ayestas, 
    138 S. Ct. at 1093
    ). Indeed, Mahdi suggests “the District court was
    required to provide” him with the requested funds “to demonstrate that he could overcome
    the procedural default” on his race-based trauma claim. Opening Br. 55 (emphasis added).
    We find no merit in Mahdi’s argument. Before turning to its substance, however,
    we observe at the outset that the factual premise upon which it rests is contrary to the
    record. In his ex parte emergency motion to amend the budget, Mahdi represented that the
    only “recently discovered evidence” warranting further review as a potential Martinez
    claim was that his father was descended from the union between a slave and his owner.
    J.A. 29. The record, however, refutes Mahdi’s claim because it plainly shows that “the
    history of Mr. Mahdi’s paternal side of the family,” specifically the fact that he is a direct
    descendent “from the relationship between a slave-owner and a slave,” J.A. 29–30, was
    expressly presented to the PCR court during the evidentiary hearing, see J.A. 2496
    (Lawanda testifying that Nancy’s ancestor “was the product of a relationship between a
    slave and an [I]rish woman” and that the “woman was sent to Boston with child and the
    father of the child disappeared, [meaning he] was never seen again”); J.A. 2959 (Dr.
    66
    Cooper-Lewter’s social history of Mahdi’s family stating that Shareef’s “great-
    grandmother was a white woman from Broadnax, Virginia” who was “impregnated by the
    family’s black gardener who is believed to have been subsequently murdered by her
    family”).
    The district court could not have abused its discretion by denying a motion for
    supplemental funding that, on its face, was premised entirely on “recently discovered
    evidence” that was already developed and presented to the PCR court. Thus, Mahdi’s
    efforts to expand this previously discovered evidence into a Martinez claim had little
    chance of bearing fruit because the PCR court had already heard this same evidence. See
    Vandross v. Stirling, 
    986 F.3d 442
    , 450 (4th Cir. 2021) (noting that one of the requirements
    for invoking Martinez is that “it is likely that no state court will hear the prisoner’s claim”).
    The district court was therefore well within its “broad discretion,” Ayestas, 
    138 S. Ct. at 1094
    , in concluding the requested funding was not “reasonably necessary,” 
    18 U.S.C. § 3599
    (f).
    But even looking past this disqualifying defect, as the district court did, and
    considering the merits of Mahdi’s argument, we would reach the same conclusion. We note
    that the district court did not cite Ayestas or expressly set out that case’s framework in its
    initial decision. But it couldn’t have, given that the Supreme Court decided Ayestas one
    year after the district court entered its order. Nevertheless, the court did consider the exact
    argument Mahdi now presents when it rejected his motion to alter or amend the decision.
    In doing so, the district court explained and applied the three-pronged Ayestas standard,
    making clear that it had denied the funding request because: (1) “counsels’ mitigation
    67
    investigator had already gathered all of the pertinent factual information counsel planned
    to allege [that] trial and PCR counsel should have presented and that counsel had already
    formed reasoned arguments as to why that information was critical to Mahdi’s mitigation
    presentation”; and (2) it “could not discern from counsels’ request what additional value a
    psychological report on this subject would offer and, thus, could not find the requested
    services reasonably necessary.” J.A. 912. In other words, under Ayestas, the district court
    determined the services were not “reasonably necessary” because they were cumulative,
    unlikely to generate additional useful and admissible evidence, and lacked merit. That
    determination was not an abuse of discretion, and it negates Mahdi’s main contention that
    the court failed to consider his funding request in light of Ayestas.
    Furthermore, as the district court pointed out in its first denial order, at no point in
    Mahdi’s emergency motion or at any point thereafter did he identify any themes that he
    intended to pursue through this supplemental funding request or make even a minimal
    showing that he would be able to overcome the procedural bar to warrant review. Nor did
    he forecast what Dr. Hill’s report would contribute beyond the information his previously
    approved $34,500 in funding for a mitigation investigator and social historian had already
    yielded. 31 See J.A. 40 (“Counsel has not set out why the issue of trial counsel’s alleged
    ineffectiveness regarding the failure to present mitigation evidence could not be fully
    31
    We observe that this appears to be the entirety of what Mahdi asked for in his
    initial proposed budget. See J.A. 11 (“Petitioner previously submitted a budget in this case,
    which was approved by the Court.”). Eventually, Mahdi determined he did not need a social
    historian. As a result, he did not use the $12,500 allocated for that expert. But he never
    asked that those funds be reallocated to Dr. Hill. Rather, his ex parte motion sought $25,000
    in addition to the $34,500 he had already received.
    68
    developed through the use of the mitigation investigator and social historian. While counsel
    may find it preferable to present this claim through a psychologist with a specialty in race-
    based trauma, the court finds such an expert unnecessary to fully develop the claim of
    ineffective assistance of counsel in regard to mitigation evidence.”). Instead, Mahdi
    presented what he incorrectly claimed to be a newly discovered fact—that his father was
    descended from the union between a slave and his owner—of which he had no knowledge
    at the time he committed his crimes. Mahdi offered no context for how this previously
    presented fact could have played a role in Captain Myers’ murder. Nor did he present any
    compelling argument in his emergency motion justifying the expenditure of $25,000 to
    convert this latent fact into a Martinez claim. What’s more, despite the district court’s
    specific ruling in the first denial order, Mahdi wholly failed to address in his motion to alter
    or amend why Dr. Hill’s services were warranted. See J.A. 912 (“In the current briefing,
    Mahdi broadly asserts the necessity of the psychologist’s services and conclusively alleges
    that those services would enable him to establish both prongs of his Martinez claim . . . ,
    but [he] still fails to ‘articulat[e] specific reasons why the services [were] warranted.’”
    (citing Ayestas, 
    138 S. Ct. at 1094
    ) (alterations in original)).
    The dissent suggests that in reaching this conclusion, we “ignore[] . . . the expertise
    that mental health clinicians bring to the table.” Diss. Op. 116. But we cannot ignore what
    wasn’t presented to the district court or to this Court. In his response to the district court’s
    ex parte text order, Mahdi suggested that Dr. Hill would “be able to examine the impact of
    [race and his family history] on Mr. Mahdi in the context of his unique ancestry and
    extrinsic and intrinsic racial identity.” J.A. 31. He further suggested that Dr. Hill would
    69
    “systemically evaluate how Mr. Mahdi’s background, racial identity, and the trauma that
    he experienced emboldened his ‘survivalist’ mentality.” J.A. 32. Thus, he concludes, Dr.
    Hill would “tie together cogent and powerful mitigation themes that have not yet been
    presented in this case.” J.A. 33.
    But these vague representations were made in the context of Mahdi’s initial ex parte
    motion, which was premised entirely on the “recently discovered evidence” concerning his
    slave lineage and Dr. Hill’s ability to help “develop and present” it. J.A. 11. Again, in his
    response filing, Mahdi made clear that the “‘recently discovered evidence’ . . . that
    provide[d] the basis for an additional expert witness” was his assertion that “[t]rial counsel
    and PCR counsel failed to investigate, in detail, [his] genealogy.” J.A. 29 (emphasis added).
    At no point, despite multiple opportunities and invitations to do so, did Mahdi offer any
    justification for how yet another mental health professional’s assessment of his genealogy
    would help him “tie together cogent and powerful mitigation themes” for the court to
    understand his ineffective assistance claim beyond those he was already able to present
    through Dworkin. J.A. 33. Nor did Mahdi provide even a hint of what those “themes” might
    have been or how Dr. Hill’s assessment would assist in developing them. J.A. 33. Unlike
    the dissent, we decline to speculate and fill in those gaps for him.
    Mahdi has been evaluated by no less than seven mental health experts since his
    arrest for Captain Myers’ murder. Dr. Hill would have been at least the eighth. Particularly
    relevant here, Mahdi’s own expert witness in the PCR court, Dr. Cooper-Lewter, had
    already conducted an extensive evaluation of Mahdi’s race-based trauma and family
    history. See, e.g., J.A. 2955 (examining the “Family and Cultural Context” of Mahdi’s
    70
    upbringing, including Dr. Cooper-Lewter’s belief that they were “fragile people who were
    often overwhelmed by their efforts to find acceptance in society, especially in light of racial
    and socioeconomic issues”); J.A. 2956 (addressing Shareef’s “passionate[]” and
    “religious[]” lectures “about the ‘unfairness’ of white people”); J.A. 2957 (summarizing
    Mahdi’s experiences at Wallens Ridge, which he maintains were filled with “racial
    epithets” and threats of violence, proving “that everything his father taught him was true”);
    J.A. 2958–65 (providing a detailed social history of Mahdi’s family, including the “social
    limitations and frustrations of the[] cultural and racial relations growing up in the Jim Crow
    South,” his slave lineage, Nancy’s efforts for she and her children to “pass for white,” and
    Shareef’s intense racial views and animus towards white people); J.A. 2978–80 (discussing
    Shareef’s rantings, home-schooling, and survivalist training to protect his children from
    “white folks coming to kill them”). And Mahdi never delineated for the district court what
    Dr. Hill’s additional analysis of these topics would “bring to the table,” Diss. Op. 116,
    beyond what Dr. Cooper-Lewter’s review had already contributed.
    At bottom, Mahdi did not present any meaningful argument beyond his own ipse
    dixit representations as to why his supplemental request for funding—that is, beyond what
    had already been provided—was “reasonably necessary.” We cannot say that the district
    court abused its discretion by denying Mahdi carte blanche to pursue any theory he wished
    based on nothing more than his vague request. See Hartsell, 127 F.3d at 349 (“[A]
    defendant does not have the right to public funding for all possibly helpful avenues of
    investigation or all possibly useful expert services, but only to the level of support required
    by the Due Process Clause.”). And Ayestas does not compel a contrary result.
    71
    The Fifth Circuit reached the same conclusion in Jones v. Davis, 
    927 F.3d 365
     (5th
    Cir. 2019). There, the petitioner—raising a similar argument to the one Mahdi presents
    here—asserted that the district court improperly denied his request for investigative
    funding because it failed to follow the rubric set out in Ayestas (which, like here, post-
    dated the district court’s decision). 
    Id.
     at 373–74. The court had denied the petitioner’s
    request because “he had not shown that he was likely to uncover anything beyond what his
    experts had already addressed.” 
    Id. at 374
    . The Fifth Circuit affirmed, holding that
    “[b]ecause the reasons the district court gave for its ruling remain sound after Ayestas, . . .
    remand [was] unnecessary.” 
    Id.
     The same is true here.
    Moreover, this Court’s decision in Wright—upon which the district court relied in
    rejecting Mahdi’s expert funding request—requiring petitioners to present a “substantial
    question” over an issue to secure funding, 
    151 F.3d at 163
    , is a far cry from the Fifth
    Circuit’s practice condemned in Ayestas, which required petitioners to demonstrate a
    “substantial need” for funding by essentially “prov[ing] that [they] will be able to win relief
    if given the services [they sought],” 
    138 S. Ct. at 1094
     (second emphasis added). Indeed,
    Wright’s requirement aligns with the second part of the Ayestas rubric—i.e., a petitioner
    must establish that the evidence he seeks to develop is useful and admissible. See Wright,
    
    151 F.3d at 163
     (noting that “a substantial question” must “exist[] over an issue requiring
    expert testimony for its resolution and the defendant’s position cannot be fully developed
    without professional assistance” in order to justify the expenditure of funds). In other
    words, Wright stands for the uncontroversial proposition that in order to justify expert
    funding, a petitioner must show that there is an issue warranting expert review. Ayestas did
    72
    nothing to undermine that requirement. See 
    138 S. Ct. at 1094
     (holding that “the
    ‘reasonably necessary’ test requires an assessment of the likely utility of the services
    requested”). And Mahdi did nothing to satisfy it. See 
    id.
     (approving the requirement that
    “an applicant must articulate specific reasons why the services are warranted”).
    The dissent suggests that the district court erred by “impos[ing] a strict necessity
    requirement” mandating that Mahdi prove “it was impossible to develop his claim without
    Dr. Hill.” Diss. Op. 111−112. There is no basis in the record for that contention. The district
    court simply required Mahdi to specify why this “recently discovered evidence”
    concerning his genealogy necessitated the assistance of a psychology expert in addition to
    those experts for whom funding had already been allocated. And, after being afforded
    multiple opportunities to do so, Mahdi failed to present any explanation as to why Dr. Hill’s
    assistance was “reasonably necessary” in light of what he had already received. As a result,
    the district court did not abuse its discretion in denying his request.
    The dissent appears to take issue with the district court for applying any standard in
    reviewing Mahdi’s supplemental funding request as opposed to the limitless one it
    proposes. See Diss. Op. 111 n.5 (suggesting § 3599 imposes no specificity requirement and
    grants broad access for petitioners to hire experts without offering any suggestion of what
    those experts may uncover). To adopt this reading of 
    18 U.S.C. § 3599
     as compelling courts
    to grant funding requests whenever counsel subjectively deems them necessary would
    eviscerate any semblance of their discretionary function. The Supreme Court did not
    establish such a broad construction in Ayestas. And we decline to do so here. We therefore
    affirm the district court’s denial of Mahdi’s supplemental request for expert funding.
    73
    B. The IAC Claims
    We turn next to the district court’s denial of Mahdi’s IAC claims, which we review
    de novo. Grueninger v. Dir., Va. Dep’t of Corr., 
    813 F.3d 517
    , 523 (4th Cir. 2016). We
    first set out the standards guiding that review.
    1. Standards of Review
    a. AEDPA Deference
    Under the Antiterrorism and Effective Death Penalty Act (“AEDPA”), federal
    courts may “entertain” an application for a writ of habeas corpus from an inmate in state
    custody “in violation of the Constitution or laws or treaties of the United States.” 
    28 U.S.C. § 2254
    (a). In doing so, we follow “Congress’ prohibition on disturbing state-court
    judgments . . . absent an error that lies beyond any possibility for fairminded
    disagreement.” Mays, 141 S. Ct. at 1146. Thus, § 2254 “is not to be used as a second
    criminal trial, and federal courts are not to run roughshod over the considered findings and
    judgments of the state courts that conducted the original trial and heard the initial appeals.”
    Williams v. Taylor, 
    529 U.S. 362
    , 383 (2000).
    To that end, federal courts cannot grant habeas relief under § 2254 unless the state
    PCR court’s decision: (1) “was contrary to” clearly established Supreme Court case law;
    (2) “involved an unreasonable application” of the same; or (3) “was based on an
    unreasonable determination of the facts in light of the” record before it. 
    28 U.S.C. § 2254
    (d)); Harrington v. Richter, 
    562 U.S. 86
    , 100 (2011); Vandross, 986 F.3d at 449.
    This standard is “intentionally difficult to meet” to safeguard principles of comity, finality,
    and federalism. Woods v. Donald, 
    575 U.S. 312
    , 316 (2015) (per curiam).
    74
    A decision is “contrary to” clearly established federal law “if the state court applies
    a rule different from the governing law set forth in [the Supreme Court’s] cases, or if it
    decides a case differently than [the Supreme Court has] done on a set of materially
    indistinguishable facts.” Bell v. Cone, 
    535 U.S. 685
    , 694 (2002). Stated differently, the
    petitioner must show that the state court’s decision was “diametrically different, opposite
    in character or nature, or mutually opposed” to federal law as determined by the Supreme
    Court. Vick v. Williams, 
    233 F.3d 213
    , 216 (4th Cir. 2000).
    For an “application of federal law” to be “unreasonable,” it must be “objectively”
    so. Owens v. Stirling, 
    967 F.3d 396
    , 411 (4th Cir. 2020). To qualify, the state court must
    “correctly identif[y] the governing legal principle from the Supreme Court’s decisions but
    unreasonably appl[y] that principle to the facts of the particular case.” Tyler v. Hooks, 
    954 F.3d 159
    , 166 (4th Cir. 2019). The state court’s decision must be “so lacking in justification
    that there was an error well understood and comprehended in existing law beyond any
    possibility for fairminded disagreement.” Harrington, 
    562 U.S. at 103
    .
    Finally, determinations of facts are “unreasonable” when they are “sufficiently
    against the weight of the evidence.” Williams v. Stirling, 
    914 F.3d 302
    , 312 (4th Cir. 2019)
    (quoting Winston v. Kelly, 
    592 F.3d 535
    , 554 (4th Cir. 2010)). That said, a “state court’s
    factual determinations are presumed correct, and the petitioner must rebut this presumption
    by clear and convincing evidence.” Bennett v. Stirling, 
    842 F.3d 319
    , 322 (4th Cir. 2016);
    accord § 2254(e)(1). “We must be especially deferential to the state PCR court’s findings
    on witness credibility, and we will not overturn the court’s credibility judgments unless its
    error is stark and clear.” Elmore v. Ozmint, 
    661 F.3d 783
    , 850 (4th Cir. 2011). Thus, “[a]
    75
    state-court factual determination is not unreasonable merely because the federal habeas
    court would have reached a different conclusion in the first instance.” Burt v. Titlow, 
    571 U.S. 12
    , 18 (2013) (quoting Wood v. Allen, 
    558 U.S. 290
    , 293 (2010)).
    b. Procedural Hurdles
    Before we can consider whether relief is available through one of § 2254’s three
    narrow exceptions, however, the petitioner must first demonstrate that he has cleared a
    series of procedural hurdles. For example, the petitioner must exhaust his state court
    remedies, 
    28 U.S.C. § 2254
    (b)(1)(A), by “present[ing] his claim to the state’s highest
    court,” Matthews v. Evatt, 
    105 F.3d 907
    , 911 (4th Cir. 1997), abrogated on other grounds
    by United States v. Barnette, 
    644 F.3d 192
     (4th Cir. 2011), including “both the operative
    facts and the controlling legal principles associated with each claim,” Longworth v. Ozmint,
    
    377 F.3d 437
    , 448 (4th Cir. 2004).
    “A distinct but related limit on the scope of federal habeas review is the doctrine of
    procedural default”—often referred to as a procedural bar—one example of which occurs
    “when a habeas petitioner fails to exhaust available state remedies and the court to which
    [he] would be required to present his claims in order to meet the exhaustion requirement
    would now find the claims procedurally barred.” Breard v. Pruett, 
    134 F.3d 615
    , 619 (4th
    Cir. 1998); see also Reed v. Ross, 
    468 U.S. 1
    , 11 (1984) (stating that a petitioner’s failure
    to abide by a state court’s procedural rules for presenting claims in state court results in a
    procedural default of those claims in federal court absent “cause and actual prejudice”). In
    addition, procedural default occurs when “a state court clearly and expressly bases its
    dismissal of a habeas petitioner’s claim on a state procedural rule, and that procedural rule
    76
    provides an independent and adequate ground for the dismissal.” Breard, 
    134 F.3d at 619
    .
    Relevant here, a claim is procedurally barred if the petitioner “fail[s] to raise [it] in his
    petition for certiorari to the South Carolina Supreme Court for review of the State PCR
    Court’s decision.” Longworth, 
    377 F.3d at 447
    .
    Petitioners may nevertheless overcome this bar in limited circumstances by
    “demonstrat[ing] cause for the default and actual prejudice.” Sigmon v. Stirling, 
    956 F.3d 183
    , 198 (4th Cir. 2020) (quoting Coleman v. Thompson, 
    501 U.S. 722
    , 750 (1991)). 32 To
    establish “cause,” the petitioner must show “‘that some objective factor external to the
    defense impeded counsel’s efforts’ to raise the claim in state court at the appropriate time,”
    Breard, 
    134 F.3d at 620
     (quoting Murray v. Carrier, 
    477 U.S. 478
    , 488 (1986)), or that
    “the factual or legal basis for the claim was not reasonably available . . . at the time of the
    state proceeding,” Roach v. Angelone, 
    176 F.3d 210
    , 222 (4th Cir. 1999). “An attorney
    error does not qualify as ‘cause’ . . . unless [it] amounted to constitutionally ineffective
    assistance of counsel.” Davila v. Davis, 
    137 S. Ct. 2058
    , 2062 (2017). Generally,
    “[b]ecause a prisoner does not have a constitutional right to counsel in state postconviction
    proceedings, ineffective assistance in those proceedings does not qualify.” 
    Id.
    A narrow exception exists under the Supreme Court’s decision in Martinez “when
    (1) the state PCR court is the first occasion for raising the claim,” which is the case in South
    32
    Petitioners may also overcome the procedural bar if they can establish that a
    “fundamental miscarriage of justice would result from” the federal court’s failure to
    consider their claim. Farabee v. Clarke, 
    967 F.3d 380
    , 395 (4th Cir. 2020). To do so, the
    petitioners must demonstrate they are actually innocent, which requires “factual innocence,
    not mere legal insufficiency.” Bousley v. United States, 
    523 U.S. 614
    , 623 (1998). Mahdi
    makes no such argument here.
    77
    Carolina; “(2) the petitioner’s counsel provided ineffective assistance in the PCR court”;
    and “(3) it is likely that no state court will hear the prisoner’s claim.” Vandross, 986 F.3d
    at 450. Thus, a petitioner
    satisfies Martinez by showing, first, that initial postconviction counsel
    performed deficiently, under the first prong of Strickland, by failing to
    exhaust the underlying ineffective-assistance-of-trial-counsel claim, but not
    that said counsel’s deficient performance was prejudicial, under the second
    prong of Strickland; and second, that the underlying claim is substantial, or
    has some merit, with respect to both prongs of Strickland.
    Owens, 967 F.3d at 423. To be clear, the Supreme Court created this narrow exception to
    be applicable only to allegations of IAC by PCR counsel. It does not apply to claims of
    IAC by PCR appellate counsel. See Johnson v. Warden of Broad River Corr. Inst., No. 12-
    7270, 
    2013 WL 856731
    , at *1 (4th Cir. 2013) (unpublished) (per curiam) (“Accordingly,
    because Johnson alleges only ineffective assistance of appellate postconviction counsel,
    his allegations do not constitute cause for his failure to exhaust under the limited exception
    in Martinez.”).
    c. IAC
    To establish IAC, a petitioner must prove: (1) his counsel was deficient in his
    representation; and (2) he was prejudiced as a result. Strickland, 466 U.S at 687. For the
    first prong, the petitioner must show that “counsel’s representation fell below an objective
    standard of reasonableness.” 
    Id. at 688
    . Stated differently, “[t]he challenger’s burden is to
    show that counsel made errors so serious that counsel was not functioning as the ‘counsel’
    guaranteed the defendant by the Sixth Amendment.” Harrington, 
    562 U.S. at 104
    . To
    satisfy the second prong, a petitioner must show that “there is a reasonable probability that,
    78
    but for counsel’s unprofessional errors, the result of the proceeding would have been
    different.” Strickland, 
    466 U.S. at 694
    . In the context of a guilty plea, the petitioner has to
    show that “there is a reasonable probability that, but for counsel’s errors, [he] would not
    have pleaded guilty and would have insisted on going to trial.” Hill v. Lockhart, 
    474 U.S. 52
    , 59 (1985).
    We are ever mindful that “[j]udicial scrutiny of counsel’s performance must be
    highly deferential,” and “court[s] must indulge a strong presumption that counsel’s conduct
    falls within the wide range of reasonable professional assistance.” Strickland, 
    466 U.S. at 689
    . And when we apply Strickland and § 2254’s highly deferential standards “in tandem,
    [our] review is doubly so.” Harrington, 
    562 U.S. at 105
    .
    As the Supreme Court directs, we only discern “whether the state court’s application
    of the Strickland standard was unreasonable. This is different from asking whether defense
    counsel’s performance fell below Strickland’s standard.” 
    Id. at 101
    . The critical question
    thus is not whether we or the district court can see a “substantial . . . likelihood of a different
    result” had counsel taken a different approach. Cullen, 
    563 U.S. at 189
    . Rather, “[a]ll that
    matter[s] [is] whether the [South Carolina] court, notwithstanding its substantial ‘latitude
    to reasonably determine that a defendant has not [shown prejudice],’ still managed to
    blunder so badly that every fairminded jurist would disagree.” Mays, 141 S. Ct. at 1149
    (final alteration in original) (quoting Knowles v. Mirzayance, 
    556 U.S. 111
    , 123 (2009)).
    That is a very high bar.
    ****
    Having set out the relevant standards of review, we now turn to Mahdi’s claims.
    79
    2. The Jury Sentencing Claim
    In Mahdi’s first IAC claim, he contends the PCR court erred in finding trial counsel
    were not ineffective for purportedly failing to explain the general proposition that “jury
    sentencing may actually result in a life sentence, while on the same facts and arguments
    judge sentencing may result in a death sentence.” Opening Br. 76. He maintains the district
    court’s conclusion that this claim was “directly contradicted by the record” improperly
    interpreted the facts in a “light most favorable to” the State rather than to him as the non-
    moving party. See 
    id.
     According to Mahdi, “[a] description of ‘pluses and minuses’ does
    not show that [he] was made aware by his trial counsel that [the trial court’s] sentencing
    could,” in theory, “be more likely to result in a death sentence than a jury’s sentencing.”
    Opening Br. 77. Nor, Mahdi alleges, does the fact that he understood “how a jury . . .
    sentencing would proceed” necessarily show that he knew how a judge sentencing would
    proceed. J.A. 537. 33 We find Mahdi’s argument without merit. 34
    33
    Mahdi also challenges the district court’s rejection of his argument that trial
    counsel were ineffective because “they had not obtained a guarantee that the judge would
    not impose a death sentence” before advising him to plead guilty. Reply Br. 15–16; Mahdi,
    
    2018 WL 4566565
    , at *45. Because Mahdi raised this argument for the first time in his
    reply brief, it is waived, and we do not consider it. Metro. Reg’l Info. Sys., Inc. v. Am. Home
    Realty Network, Inc., 
    722 F.3d 591
    , 602 n.13 (4th Cir. 2013).
    34
    The district court reached the merits of the Jury Sentencing Claim without
    addressing whether it was procedurally barred. See Mahdi, 
    2018 WL 4566565
    , at *44 n.42.
    As previously noted, Mahdi did not appeal the PCR court’s rejection of this claim in his
    first PCR proceeding. And the Supreme Court of South Carolina rejected the Jury
    Sentencing Claim on procedural grounds during the second proceeding. As such, the claim
    is procedurally barred. See Longworth, 
    377 F.3d at 447
    . However, because the Parties did
    not brief this issue and the procedural bar is not jurisdictional, see 
    28 U.S.C. § 2254
    (b)(2);
    Lambrix v. Singletary, 
    520 U.S. 518
    , 523 (1997), we too will sidestep that analysis for this
    claim and address the district court’s judgment on the merits.
    80
    As a threshold matter, neither the Parties nor the district court address the PCR
    court’s factual finding that Mahdi waived and abandoned the Jury Sentencing Claim by
    failing to “specify the jury sentencing advantages to which he allude[d],” “testify,” “offer[]
    . . . testimony or other evidence,” or “question any of his former appointed attorneys on
    this issue” at the PCR evidentiary hearing. J.A. 7528. And Mahdi has pointed to no record
    evidence or presented any colorable argument in his briefs before this Court suggesting
    this aspect of the PCR court’s decision was “contrary to, or involved an unreasonable
    application of, clearly established Federal law” or “based on an unreasonable determination
    of the facts in light of the evidence presented in the State court proceeding.” 
    28 U.S.C. § 2254
    (d); see also Grayson O Co. v. Agadir Int’l LLC, 
    856 F.3d 307
    , 316 (4th Cir. 2017)
    (“A party waives an argument by failing to present it in its opening brief or by failing to
    develop its argument—even if its brief takes a passing shot at the issue.” (cleaned up)).
    Moreover, Mahdi has failed to submit any evidence—“clear and convincing,” Bennett, 842
    F.3d at 322, or otherwise—to overcome the presumption that the PCR court’s factual
    determination regarding his waiver is correct. Thus, we affirm the district court’s denial of
    Mahdi’s Jury Sentencing Claim on this independent ground. See Scott v. United States, 
    328 F.3d 132
    , 137 (4th Cir. 2003) (reiterating that the Court is “entitled to affirm on any ground
    appearing in the record”).
    Even if we were to reach the merits of Mahdi’s argument, we find no flaw in the
    district court’s conclusion that the record establishes he was fully advised of his rights to a
    jury trial and sentencing, as well as the possibility that a jury could sentence him to life.
    Specifically, before pleading guilty, trial counsel “discussed with [Mahdi the] options that
    81
    [were] available with regards to this case” and observed that he was “aware of the fact that
    there are two phases to a trial, the guilt phase and also the sentencing phase.” J.A. 1178.
    Trial counsel told Mahdi “that there [were] no guarantees with regards to either process”
    and that “there [were] certain pluses and minuses with [a] jury.” J.A. 1179. Trial counsel
    further
    explained to [Mahdi] his constitutional rights, including the right to have a
    jury trial and the rights to have the jury determine whether his sentence would
    be life without the possibility of parole, if he were to be found guilty during
    the guilt phase of the trial, or the jury could return a verdict for death.
    J.A. 1193.
    Before accepting Mahdi’s plea, the trial court emphasized that “in order for a jury
    to find [him] guilty, all 12 jurors must unanimously agree” and “in order for a jury to
    recommend a death sentence, . . . all 12 jurors must agree to recommend the death
    sentence.” J.A. 1197. The trial court also explained that “sentencing is conducted by the
    Judge in any capital case where a defendant pleads guilty.” J.A. 1184. Mahdi indicated that
    he understood he had “the constitutional right to have the jury decide [his] guilt or
    innocence and, also . . . the constitutional right to have the jury determine [his] sentence.”
    J.A. 1197. And he testified that trial counsel had “made [him] fully aware of” “the
    constitutional safeguards that [he had] and the essential protections inherent in a jury trial.”
    J.A. 1200. To that end, Dr. Cross confirmed Mahdi’s understanding of both judicial and
    jury sentencing, as well as “the possible consequences for each,” before he pleaded guilty.
    J.A. 1189.
    On this record, there is simply no basis to conclude trial counsel’s performance was
    82
    deficient in this regard. And there is even less ground for finding the PCR court’s
    determination was “so lacking in justification that there was an error well understood and
    comprehended in existing law beyond any possibility for fairminded disagreement,”
    Harrington, 
    562 U.S. at 103
    , or “sufficiently against the weight of the evidence,” Williams,
    914 F.3d at 312. Accordingly, we cannot say that the PCR court’s rejection of Mahdi’s
    Jury Sentencing Claim was unreasonable.
    And even if trial counsel were somehow deficient in this regard, the PCR court’s
    determination that Mahdi could not demonstrate prejudice was reasonable. As the PCR
    Court observed, there is nothing in the record to suggest that Mahdi “would not have
    pleaded guilty and would have insisted on going to trial.” Hill, 
    474 U.S. at 59
    . To the
    contrary, trial counsel made clear during the PCR hearing that the defense “wanted [the
    trial court] to sentence” Mahdi because “sitting judges that have practiced law for an
    extensive period of time and are also involved in the prosecution and defense of criminal
    cases . . . are desensitized,” having “seen plenty of murder cases over and over and over
    again as opposed to a lay person.” J.A. 2883–84. And the PCR court found trial counsel’s
    “testimony on this issue to be credible.” J.A. 7530. Mahdi has presented no argument
    suggesting this determination amounted to an error that is both “stark and clear.” Elmore,
    
    661 F.3d at 849
    . As such, we must be “especially deferential” to it. 
    Id.
    What’s more, trial counsel’s testimony regarding Mahdi’s desire to proceed before
    the judge for sentencing is especially convincing given the facts of this case. The
    aggravating evidence was simply overwhelming. First, there were the grisly details about
    the events leading up to Captain Myers’ murder, including the surveillance video capturing
    83
    Mahdi’s execution-style murder of Boggs 35 and Pitts’ testimony recounting the violent
    carjacking. Trial counsel also had to consider the horrid facts surrounding Captain Myers’
    murder itself, including Officer Curtis’ description of the scene, Ross’ summary of her
    autopsy report and the state of Captain Myers’ body, as well as the numerous friends and
    family members’ testimony about the impact Captain Myers’ murder had on their lives.
    Further, trial counsel knew they had to contend with the events surrounding Mahdi’s arrest,
    especially Sergeant Frost’s testimony recalling Mahdi’s statement that the only reason he
    did not fire the assault rifle was because the gun’s “selector was stuck on a three shot and
    [he did not] think [he] could have . . . shot [Sergeant Frost], the other cop, and . . . that
    fucking dog.” J.A. 1243.
    Trial counsel were also faced with overwhelmingly negative evidence concerning
    Mahdi’s atrocious criminal record and maladaptive behavior while in custody. This
    included Mahdi’s repeated statements showing his utter disregard for human life. See, e.g.,
    J.A. 1280 (telling officers after the standoff that he was “going to kill a cop before [he]
    die[s]”); J.A. 1310 (apprising officers after fighting them that “he should have killed” his
    mother); J.A. 1363 (informing his neighbor that he “was going to knock [someone] off”);
    J.A. 1465 (stating that he would kill an SCDC officer “the next chance he [got]”); J.A.
    1482, 1497 (threatening to murder Officer Driggers); J.A. 1978 (threatening to “become
    35
    The district court granted Mahdi’s motion in limine to exclude the video of Boggs’
    murder from being shown to the jury during trial. Nevertheless, the trial court allowed the
    tape to be admitted into evidence over Mahdi’s objection during sentencing. There is no
    reason to believe—and Mahdi has presented none—that the trial court would have refused
    to admit the tape had the sentencing been conducted by a jury.
    84
    homicidal” while in DJJ custody). This evidence also included other violent conduct,
    including his participation in the standoff with his father, fighting with police officers,
    stabbing Rivera, and repeated disciplinary infractions while in custody. Finally, there was
    significant evidence concerning his efforts to escape from law enforcement and
    confinement, including his comments to Coulson, testimony from SCDC Officers Prioleau
    and Lane, as well as the fact that he had been caught smuggling a homemade handcuff key
    into the courthouse during the opening days of trial.
    At bottom, the aggravating evidence overwhelmingly supports the PCR court’s
    conclusion there was no “reasonable probability he would not have pled guilty, and would
    have proceeded to trial,” in light of the “record, including counsel’s credible testimony, the
    record of the plea proceeding, and the evidence that would have been submitted to the
    chosen jury.” J.A. 7531. Thus, we conclude the PCR court’s application of Strickland was
    reasonable, see Harrington, 
    562 U.S. at 101
    , and the district court properly denied Mahdi’s
    § 2254 petition on this ground.
    3. The Mitigation Evidence Claim
    Mahdi argues the district court erred in denying relief on his Mitigation Evidence
    Claim for two reasons. First, he alleges the court “improperly concluded that [he]
    procedurally defaulted on all but one of his mitigation [sub]claims”—that trial counsel
    were deficient for failing to call non-family lay witnesses to testify on his behalf. Opening
    Br. 56. Second, Mahdi maintains the court erred in finding the PCR court’s rejection of his
    non-procedurally barred subclaim concerning non-family lay witnesses was an objectively
    reasonable application of Strickland. We address each argument in turn.
    85
    a. Procedurally Barred Claims
    Mahdi submits he can overcome the procedural bar on his defaulted subclaims by
    demonstrating PCR counsel’s alleged failure to uncover evidence obtained by federal
    habeas counsel. Though he raised six theories to overcome this hurdle before the district
    court, he only presses two here: (1) that he can establish cause and prejudice under
    Martinez; and (2) that the newly discovered evidence set out in Dworkin’s affidavit
    fundamentally alters his Mitigation Evidence Claim. 36 Neither argument holds water.
    i. Martinez Cause and Prejudice
    Mahdi asserts that federal habeas counsel’s investigation revealed substantial
    mitigation information that bolstered both his Mitigation Evidence Claim and rebutted the
    State’s evidence in aggravation. Specifically, he argues that had PCR counsel presented
    the five areas of newly discovered evidence set out in Dworkin’s affidavit, “there is at least
    a reasonable probability that the outcome of the PCR proceeding would have been
    different.” Opening Br. 58.
    The State responds that Mahdi cannot rely on Martinez to excuse the procedural
    default because the narrow exception that decision created applies only to allegations of
    IAC by PCR counsel, not PCR appellate counsel. In Martinez, the Supreme Court
    specifically limited its narrow application to first-level collateral review actions, reiterating
    36
    Though Mahdi sets out the other four theories in a footnote in his opening brief,
    see Opening Br. 57 n.14, we conclude he has waived any challenges to the district court’s
    rejection of them. See Wahi v. Charleston Area Med. Ctr., Inc., 
    562 F.3d 599
    , 607 (4th Cir.
    2009) (holding that an issue raised in a footnote and addressed with only a single
    declarative sentence asserting error is waived); see also Foster v. Univ. of Md.-E. Shore,
    
    787 F.3d 243
    , 250 n.8 (4th Cir. 2015) (same for footnotes with argument).
    86
    that the new exception “does not concern attorney errors in other kinds of proceedings,
    including appeals from initial-review collateral proceedings.” 
    566 U.S. at 16
    . Thus, the
    State maintains, the fact that Mahdi has discovered additional background evidence during
    the federal habeas proceedings has no bearing on the analysis for whether his procedurally
    barred subclaims are defaulted.
    The State has the better argument. As discussed, Mahdi did not appeal the PCR
    court’s rejection of any aspect of the Mitigation Evidence Claim in the first proceeding
    apart from the denial of his subclaim that trial counsel were ineffective for failing to call
    non-family members as witnesses. And when Mahdi tried to bring up the remaining facets
    of the Mitigation Evidence Claim during the second state-court PCR proceeding, the
    Supreme Court of South Carolina rejected all of them on procedural grounds. Therefore,
    the subclaims are procedurally barred. See Longworth, 
    377 F.3d at 447
    .
    The burden now falls on Mahdi to “demonstrate cause for the default and actual
    prejudice.” Sigmon, 956 F.3d at 198 (quoting Coleman, 
    501 U.S. at 750
    ). He fails at the
    first step. There is no dispute that the “cause” for Mahdi’s procedurally defaulted subclaims
    was PCR appellate counsel’s failure to appeal their denial to the Supreme Court of South
    Carolina. But “ineffective assistance of appellate postconviction counsel . . . do[es] not
    constitute cause for his failure to exhaust under the limited exception in Martinez.”
    Johnson, 
    2013 WL 856731
    , at *1. Therefore, we affirm the district court’s determination
    87
    that Mahdi cannot overcome the procedural bar through Martinez for his defaulted
    subclaims. 37
    ii. Fundamentally Altered Claims
    In another attempt to resurrect his procedurally defaulted subclaims, Mahdi
    contends Dworkin’s newly discovered evidence “fundamentally altered” his Mitigation
    Evidence Claim because PCR counsel “offered no evidence to support claims of race-based
    trauma or the extent of Shareef’s abuse.” Opening Br. 60. Mahdi maintains “the new
    evidence places [his claim] in a significantly different and stronger posture than it was
    before the state courts,” thereby excusing the default. Reply Br. 9.
    The State responds that Mahdi did present the substance of his claim to the state
    courts, pointing to the principle that “the presentation of additional facts does not mean
    that the claim was not fairly presented.” Br. 36 (quoting Moore v. Stirling, 
    952 F.3d 174
    ,
    183 (4th Cir. 2020)). From this, it concludes “Mahdi’s claim is decidedly one of
    background information,” 
    Id. at 37
    , that may have “strengthened [his] claim that trial
    counsel should have done more” but does not “fundamentally alter” it, 
    id.
     (quoting Moore,
    952 F.3d at 185).
    We agree with the State. New evidence in a federal habeas matter fundamentally
    alters a claim in the limited situation where the petitioner did not offer any evidence to the
    state courts supporting the existence of a material fact. See Winston v. Kelly, 
    592 F.3d 535
    ,
    37
    To the extent Mahdi is trying to raise the issues presented in Dworkin’s affidavit
    as separate Martinez claims—and not as a means to overcome the otherwise procedurally
    defaulted subclaims raised in his first PCR petition—we affirm the district court’s rejection
    of them for the reasons stated in its opinion. See Mahdi, 
    2018 WL 4566565
    , at *34–38.
    88
    550 (4th Cir. 2010) (“Suppose, for example, that a petitioner on federal habeas introduces
    new evidence to establish the existence of fact X, a fact required to prove his claim. The
    claim will inevitably be stronger, regardless of the evidence the petitioner presented to the
    state courts. However, if the petitioner presented no evidence to the state courts to establish
    the existence of fact X, the claim will be fundamentally altered by the new evidence
    presented to the district court.”). “This standard is not satisfied with new bits of evidence
    but requires critical evidence that makes his claim both stronger and significantly
    different.” Moore, 952 F.3d at 183 n.8.
    At most, Dworkin’s newly discovered evidence consists of additional information
    relating to Mahdi’s troubled history and his grandmother’s interactions with trial counsel.
    And, as the State rightly observes, Mahdi presented voluminous evidence at both
    sentencing and during his first state-court PCR proceeding regarding his background and
    trial counsel’s mitigation efforts. Though this newly discovered evidence “has perhaps
    strengthened [Mahdi’s] claim, . . . it has not ‘fundamentally altered’ it.” Gray v. Zook, 
    806 F.3d 783
    , 799 (4th Cir. 2015). “The heart of the claim remains the same: his trial attorneys
    should have done more to show how [Mahdi’s troubled childhood] lessened his
    culpability.” Id.; see Moore, 952 F.3d at 183 (“When new evidence only elaborates on the
    evidence presented in state court, the claim is not fundamentally altered into a new, and
    unexhausted, claim.”). As such, the district court was correct in rejecting Mahdi’s efforts
    to overcome the procedural bar through this avenue as well.
    The dissent disagrees, indicating instead that it would vacate the district court’s
    grant of summary judgment on both subclaims and remand for further proceedings. As for
    89
    Mahdi’s race-based-trauma subclaim, the dissent posits that “[h]ad the district court
    applied the correct legal standard” to Mahdi’s supplemental funding request, Diss. Op. 120,
    it would have “granted funding to retain Dr. Hill,” id., which, in turn, would have
    supplemented Dworkin’s affidavit and, when taken together, would have presented “a
    compelling argument that his race-based trauma subclaim was ‘new,’ and that Martinez
    excused the procedural default,” id. As previously noted, the dissent is simply incorrect at
    the first step of its speculative journey. We do agree, however, that “[w]e don’t know what
    we don’t know,” Diss. Op. 121, and thus decline to conjecture about what could have been
    presented, if anything, had Mahdi answered the district court’s repeated inquiries.
    Turning to the abuse subclaim, the dissent relies entirely on Nate’s allegedly
    “substantial insight into the family dynamics,” 38 as contained in a single sentence in
    Dworkin’s ten-page affidavit. J.A. 371; see also Diss. Op. 122. Specifically, the dissent
    focuses on Nate’s claim that he can “recall[] [Mahdi] and Saleem being beaten by their
    father as children, saying that he [Nate] ‘can hear them screaming still.’” J.A. 371
    (alteration in original). That is the sole reference in the approximately 8,800-page record
    suggesting that Shareef physically abused Mahdi. In toto. Full stop. The dissent concedes
    as much. Diss. Op. 123 (“In fact, all evidence was to the contrary [i.e. that Shareef had not
    abused Mahdi].” (emphasis added)). And despite the fact that Nate provided no details as
    to the time period, frequency, or severity of the alleged abuse, the dissent nevertheless
    38
    The record provides no context for this assertion. There is no way of knowing
    what relationship, if any, Mahdi had with his cousin Nate. At most, we know Nate’s father,
    Nathan, had been unhelpful during the initial mitigation investigation and was proud of
    having identified Mahdi for the authorities.
    90
    characterizes the alleged abuse as “severe,” Diss. Op. 123, and “extreme,” id. at 123, 130
    n.14, while also referring to it as “profound and chronic trauma,” id. at 130 n.14. This
    portrayal has no basis in the record.
    Even accepting Nate’s statement, we could just as easily speculate that Nate was
    referring to a single incident when Shareef spanked Mahdi and his brother. That statement
    would have as much support in the record as the dissent’s characterizations. Nothing in the
    record gives any context to Nate’s isolated claim. We simply do not see how Nate’s vague,
    unsupported, and unqualified allegation places Mahdi’s “case in a significantly different
    and stronger evidentiary posture than it was when the state courts considered it.” Wise v.
    Warden, Md. Penitentiary, 
    839 F.2d 1030
    , 1033 (4th Cir. 1988).
    Nor do we “view[] the strength of childhood-abuse evidence as mitigating evidence
    much differently than the Supreme Court, the South Carolina trial court, the State’s trial
    counsel, and the State’s PCR counsel, among others—[the dissent] included.” Diss. Op.
    124 (footnotes omitted). The fact of this case is that there is no evidence of childhood abuse
    for us to give credence to. We will not diminish the strength of factually supported claims
    of childhood abuse by sensationalizing the unsupported allegation here, which is contrary
    to a massive record disproving any such speculation.
    To that end, we also will not fault trial or PCR counsel for failing to elicit this claim.
    The record does not support the dissent’s suggestion that Trial Counsel undertook little or
    no effort “to find favorable mitigation evidence once they grew frustrated with those who
    knew Mahdi best.” Diss. Op. 129. Nor is there any record support for the dissent’s assertion
    that “trial counsel decided that Mahdi had not been abused as a child because both the
    91
    abuser and the abused denied it.” Diss. Op. 128. 39 In actuality, to the extent trial counsel
    reached the conclusion that Shareef had not abused Mahdi, they did so after multiple
    interviews of family members, teachers, community members, and the review of reams of
    Mahdi’s medical, school, and court records. None of these raised even a scintilla of
    physical abuse, much less that Nate was a witness to anything. And Dr. Cooper-Lewter,
    one of Mahdi’s expert witnesses during the PCR hearing, reached the same answer after
    conducting an extensive investigation. See J.A. 2953–54 (detailing each of the records he
    reviewed and the family members and teachers he interviewed); J.A. 2541–42 (testifying
    that there was “no evidence in this case” of “physical violence from his father”).
    b. Non-Family Lay Witnesses
    Turning to the only non-procedurally barred subclaim, Mahdi maintains that trial
    counsel’s performance was deficient because, “[e]ven though [his] family, friends and
    community members were available, trial counsel did not present a single witness who
    personally knew [him] or who could properly bring to light the trauma [he] endured
    throughout his childhood.” Opening Br. 62. And though Mahdi acknowledges that
    39
    In any event, we must consider PCR counsel’s actions in light of the fact that
    Mahdi never provided any information suggesting Shareef physically abused him. See
    Strickland, 
    466 U.S. at 691
     (“Counsel’s actions are usually based, quite properly, . . . on
    information supplied by the defendant . . . . And when a defendant has given counsel reason
    to believe that pursuing certain investigations would be fruitless or even harmful, counsel’s
    failure to pursue those investigations may not later be challenged as unreasonable.”);
    DeCastro v. Branker, 
    642 F.3d 442
    , 456 (4th Cir. 2011) (“[T]he state court did not act
    unreasonably in refusing Petitioner’s attempt ot upend his conviction and sentence based
    on the information that he failed to timely provide to counsel.”).
    92
    Hammock’s testimony presented some of the troubled details of his life, he asserts “it was
    woefully deficient.” Opening Br. 62–63.
    The State suggests Mahdi’s argument “cannot be squared with the record.” Resp.
    Br. 33. Reiterating the PCR court’s determination “that trial counsel made reasonable
    investigation into Mahdi’s background,” Resp. Br. 29, the State emphasizes Hammock’s
    credentials and testimony related to the effect Mahdi’s “educational, parental, and role
    model issues, and other recognized risk factors . . . had on his development.” Resp. Br. 33–
    34. Moreover, the State argues, the district court correctly found the PCR court’s decision
    that the evidence presented by non-family lay witnesses during the PCR evidentiary
    hearing was cumulative of that presented during the sentencing hearing was reasonable.
    We agree that trial counsel’s performance was not deficient. As a threshold matter,
    Mahdi has presented no grounds to conclude that the PCR court’s determination that trial
    counsel “conducted a reasonable and thorough mitigation investigation and presented what
    mitigation they could that was favorable to Mahdi at the time of the sentencing
    proceeding,” J.A. 7556, was “sufficiently against the weight of the evidence,” Williams,
    914 F.3d at 312.
    As Mahdi’s South Carolina defense team’s testimony—which the PCR court found
    to be credible, see Elmore, 
    661 F.3d at 849
     (reiterating that a state PCR court’s findings on
    witness credibility” will not be overturned unless its error is “stark and clear”)—made
    clear, the mitigation investigation was far from inadequate. To begin, trial counsel hired
    Haas, a highly credentialled mitigation investigator, who testified that she met with Mahdi
    and obtained records from each school Mahdi attended, hospitals (specifically seeking his
    93
    psychiatric records), and correction facilities (including DJJ, VDOC, and SCDC). She also
    visited his schools and spoke with several teachers who knew and remembered Mahdi but
    had not spent significant amounts of time with him. Haas also met with Mahdi’s North
    Carolina mitigation investigator, and relayed information “dealing with [any] of the
    potential witnesses in the case” to the South Carolina defense team. J.A. 2776. In addition,
    trial counsel hired Hammock, a highly qualified social worker with an extensive
    background in death-penalty litigation. Along with speaking to various members of
    Mahdi’s family, Hammock testified that she met with a member of the community who
    “didn’t know much about him” as part of her efforts to “tak[e] information from anyone
    who would give information about [Mahdi], his life and his development.” J.A. 1595.
    However, as the record makes clear, Haas’ and Hammock’s work bore little fruit in terms
    of soliciting non-family lay witnesses to testify on Mahdi’s behalf. Indeed, according to
    trial counsel, they “relied on [Mahdi’s] family to identify other potential witnesses,” but
    they were “not helpful.” Mahdi, 
    2018 WL 4566565
    , at *32.
    Not only were Mahdi’s family members unhelpful in this regard, the PCR court also
    made a credibility determination that they too were unwilling to serve as witnesses or assist
    trial counsel. See J.A. 7556 (“This Court finds the testimony of counsel and their defense
    team on [the Mitigation Evidence Claim] to be credible and the present testimony of
    Mahdi’s witnesses regarding their previous willingness to testify to be not credible.”);
    Elmore, 
    661 F.3d at 849
     (reiterating that state PCR court’s credibility findings are not
    overturned absent a “stark and clear” error in judgment). Mahdi has not challenged that
    assessment.
    94
    But even if Mahdi’s family members had testified during sentencing, the evidence
    adduced during the PCR merits hearing makes clear that they would have undermined his
    key mitigation arguments. For example, Carson and Lawanda testified about Mahdi’s
    manipulative behavior, including his frequent malingering about suicide and the incident
    when he made a false claim of abuse in an effort to retaliate against them. Indeed, Carson
    told Haas that he “still laughs about this today because he feels [Mahdi] was just being
    manipulative and really wasn’t struggling [with suicide].” J.A. 2774. He also referred to
    Mahdi as a “demon” based on his behavior. J.A. 2706. Rose described Mahdi’s anger and
    violent conduct as a child, including “hit[ting his mother] a couple of times.” J.A. 2288.
    Sophia testified about an incident where Mahdi slashed his mother’s tires because she
    would not let him use her car.
    During the PCR hearing, Haas and trial counsel also testified about their interactions
    with other members of Mahdi’s family. Shareef spent most of his time during his meeting
    with Haas “talking a lot about his . . . personal beliefs,” J.A. 2773, and otherwise “refused
    to participate,” J.A. 2837. Vera refused to meet with anyone from the South Carolina
    defense team. Saleem would not speak with them. Nathan was not “helpful at all,” J.A.
    2777, and indeed “was proud of the fact that he had identified his nephew for the North
    Carolina authorities,” J.A. 2814. And Nancy “wanted to brag about the accomplishments
    of the family. She did not want to address the issues with regard to her grandson and how
    he got there.” J.A. 2816. In short, Mahdi’s family put up road block after road block in
    preventing trial counsel’s efforts to gather potential witnesses—family or otherwise—to
    testify on Mahdi’s behalf.
    95
    To that end, trial counsel did all that could be expected of them given what they had
    and undoubtedly conducted a constitutionally sufficient investigation. See Byram v.
    Ozmint, 
    339 F.3d 203
    , 209 (4th Cir. 2003) (“[C]ounsel is only required to make a
    reasonable”—not      exhaustive—“investigation     for   possible   mitigating    evidence.”
    (emphasis added)); McWee v. Weldon, 
    283 F.3d 179
    , 188 (4th Cir. 2002) (“[T]he
    reasonableness of an investigation, or a decision by counsel that forecloses the need for an
    investigation, must be considered in light of the scarcity of counsel’s time and resources in
    preparing for a sentencing hearing and the reality that counsel must concentrate his efforts
    on the strongest arguments in favor of mitigation.”). To be sure, one could always say that
    defense counsel could have done more through the lens of hindsight. And that PCR counsel
    were able to locate non-family lay witnesses willing to testify years later does not mean,
    ipso facto, that trial counsel’s investigation was deficient. “[T]here comes a point at which
    evidence . . . can reasonably be expected to be only cumulative, and the search for it
    distractive from more important duties.” Bobby v. Van Hook, 
    558 U.S. 4
    , 11 (2009) (per
    curiam); Wilson v. Greene, 
    155 F.3d 396
    , 403 (4th Cir. 1998) (holding that counsel’s
    performance is not deficient in declining “to spend valuable time pursuing what appeared
    to be an unfruitful line of investigation” (quoting Bunch v. Thompson, 
    949 F.2d 1354
    , 1364
    (4th Cir. 1991))). That trial counsel made that determination when they did in light of their
    fruitless mitigation investigation efforts does not render their performance deficient. “This
    is not a case in which the defendant’s attorneys failed to act while potentially powerful
    mitigating evidence stared them in the face or would have been apparent from documents
    any reasonable attorney would have obtained.” Bobby, 558 U.S. at 11. To the contrary,
    96
    every avenue trial counsel explored was met with resistance and dead ends. And it was not
    unreasonable or against prevailing professional norms for counsel to rely on their qualified
    mitigation team to uncover any and all possible avenues for beneficial evidence, which
    they did. See Rompilla v. Beard, 
    545 U.S. 374
    , 389 (2005) (“Questioning a few more family
    members and searching for old records can promise less than looking for a needle in a
    haystack, when a lawyer truly has reason to doubt there is any needle there.”); Sigmon, 956
    F.3d at 200–01 (holding that trial counsel’s investigation was reasonable when they used a
    mitigation expert and team); Rhode v. Hall, 
    582 F.3d 1273
    , 1283 (11th Cir. 2009) (per
    curiam) (holding it is not unreasonable for counsel to rely on a qualified mitigation
    investigator or other experts).
    We also agree with the district court that the PCR court’s determination that “much,
    if not all, of the evidence Mahdi offered at PCR regarding his family and social history”
    through non-family lay witnesses “was cumulative to the evidence presented in Mahdi’s
    capital sentencing proceeding” through Hammock’s testimony and exhibits, J.A. 7560, was
    not “sufficiently against the weight of the evidence,” Williams, 914 F.3d at 312. During the
    PCR evidentiary hearing, Mahdi’s teachers testified or submitted affidavits about the
    significant gaps in his education, his behavioral outbursts, and Shareef’s failures as a father,
    though they all acknowledged they knew nothing about Mahdi’s home life. What’s more,
    they also presented negative testimony that hurt Mahdi’s mitigation efforts. Specifically,
    they testified about Mahdi’s anger and behavioral issues, including the fact that he used to
    “draw pictures of people hanging, the nooses and things like that.” J.A. 2345.
    97
    Smith and Douglas Pond provided testimony concerning Shareef’s troubled
    behavior in the community, specifically recounting the incident at the local Whites-only
    pool. Sheriff Woodley, who testified and was cross-examined by trial counsel during the
    sentencing hearing, submitted an affidavit about Shareef’s violent behavior towards his
    mother and Vera as well as his lack of respect for authority. And Sharon Pond testified
    about Shareef’s mental health issues, though she conceded she had never met Mahdi before
    and that medical professionals ultimately did not find any health or major mental illness in
    Shareef.
    Trial counsel recognized the importance of Mahdi’s family history and background,
    which explains why Hammock alluded to all of it in her testimony during the sentencing
    hearing. Specifically, she testified about Mahdi’s “rather chaotic” childhood, J.A. 1597,
    including the extensive gaps in his education. She also testified at length concerning
    Shareef’s violent and outlandish behavior towards Nancy and Vera; his reputation for being
    “at odds with people in the community, with his own family and with law enforcement,”
    J.A. 1610; and his “inability . . . to parent appropriately and correctly,” J.A. 1597. Trial
    counsel could hardly be said to have performed deficiently by presenting evidence that
    “would have added nothing of value,” Bobby, 558 U.S. at 12, and was cumulative of what
    had already been submitted to the trial court. See Morva v. Zook, 
    821 F.3d 517
    , 530 (4th
    Cir. 2016) (“That the mitigating evidence [the petitioner] insists should have been
    presented at trial is merely cumulative to the evidence actually heard . . . further undercuts
    [his] claim for deficient performance.”). And the PCR court’s determination to that effect
    was certainly not “an error that lies beyond any possibility for fairminded disagreement.”
    98
    Mays, 141 S. Ct. at 1146. Therefore, we affirm the district court’s holding that the PCR
    court reasonably applied the first prong of the Strickland analysis to the Mitigation
    Evidence Claim.
    But even if we were to reach the prejudice prong of the Strickland analysis, we
    would reach the same conclusion as the district court. Mahdi claims that “[w]ithout the
    mitigating evidence [presented during the PCR evidentiary hearing], the [trial court] had
    no context to understand [his] criminal history, presented by the State as aggravation, as a
    product of his long-term abuse and suffering.” Opening Br. 64. Thus, in his view, the trial
    court “heard almost nothing that would humanize [Mahdi]” during the sentencing phase.
    Id. at 64 (quoting Porter v. McCollum, 
    558 U.S. 30
    , 41 (per curiam) (2009)). Had it
    possessed the “full picture of Mahdi’s life,” Opening Br. 64, he argues, “there is a
    reasonable probability that [the judge] would have struck a different balance” and
    sentenced him to life without parole 
    Id.
     (quoting, Wiggins v. Smith, 
    539 U.S. 510
    , 537
    (2003)). The State counters that Mahdi cannot show prejudice because the evidence
    adduced during the PCR evidentiary hearing would not have outweighed the overwhelming
    aggravating evidence before the trial court during sentencing.
    We agree with the State. The PCR court’s determination that Mahdi suffered no
    prejudice because the additional testimony would have added nothing of value was not so
    fundamentally flawed as to warrant habeas relief. “The question of whether counsel’s
    deficiency prejudiced the defense centers on whether there is a reasonable probability that,
    absent counsel’s errors, the sentencer would have concluded that the balance of aggravating
    and mitigating circumstances did not warrant death.” Sigmon, 956 F.3d at 192 (cleaned
    99
    up). And here, “when considered against the sheer magnitude of the aggravating evidence
    against” Mahdi, as discussed at length earlier, “it is difficult to see the allegedly
    unreasonable omission of this mitigation evidence [from the non-family lay witnesses] as
    prejudicial.” Plath v. Moore, 
    130 F.3d 595
    , 602 (4th Cir. 1997). “[I]n weighing the omitted
    evidence against that actually used to convict and sentence [Mahdi], the mitigating
    evidence seems insufficient to shift the balance in [his] favor.” Id.; accord Wong v.
    Belmontes, 558 US. 15, 20 (2009) (per curiam) (observing that to establish prejudice, the
    petitioner must show “a reasonable probability” that had counsel presented the evidence
    the court “would have returned with a different sentence”.
    It is also worth noting that each witness who testified during the PCR hearing would
    have likely introduced evidence that would have undermined Mahdi’s mitigation strategy
    at sentencing. This is exemplified by the testimony from Mahdi’s mental health experts,
    who opined that he malingered, expressed suicidality for purposes of manipulation, and
    had antisocial personality disorder. See Satcher v. Pruett, 
    126 F.3d 561
    , 572 (4th Cir. 1997)
    (finding counsel were not ineffective for declining to put on “potentially damaging
    psychiatric evidence” that the defendant had antisocial personality disorder).
    Unsurprisingly, this testimony was also consistent with the opinions from Dr. Martin and
    Dr. McKee, who reached the same conclusion.
    Therefore, even if we were to reach this second prong of the Strickland analysis, we
    would still affirm the district court’s holding.
    4. The Judicial Sentencing Claim
    Mahdi’s third IAC claim contends the district court erred in rejecting his argument
    100
    that trial counsel were ineffective for failing to object to the trial court’s sentencing in light
    of the Supreme Court’s decisions in Apprendi, 40 Ring, and Blakely. 41 In response, the State
    argues that Mahdi has procedurally defaulted the Judicial Sentencing Claim. See Resp. Br.
    45–46 & n.21–22 (raising the procedural bar argument and maintaining that it “did not
    abandon the procedural bar below and do[es] not do so here”). Mahdi suggests that if this
    Court determines the Judicial Sentencing Claim to be procedurally barred, we should
    remand for the district court to conduct an evidentiary hearing to determine whether he can
    clear the necessary hurdles to merit review. However, he cites no controlling precedent to
    support this approach. And he failed to provide any argument in his reply brief addressing
    the State’s invocation of the procedural bar. 42 See Alvarez v. Lynch, 
    828 F.3d 288
    , 295 (4th
    Cir. 2016) (“[A]n outright failure to join in the adversarial process would ordinarily result
    in waiver.”); Bonte v. U.S. Bank, N.A., 
    624 F.3d 461
    , 466 (7th Cir. 2010) (“Failure to
    respond to an argument results in waiver.”).
    As previously noted, Mahdi did not appeal the PCR court’s rejection of this claim
    in his first state PCR proceeding. And the Supreme Court of South Carolina dismissed the
    Judicial Sentencing Claim on procedural grounds during the second proceeding. See S.C.
    40
    Apprendi v. New Jersey, 
    530 U.S. 466
     (2000).
    41
    Blakely v. Washington, 
    542 U.S. 296
     (2004).
    42
    The district court reached the merits of this claim without addressing whether it
    was procedurally barred. See Mahdi, 
    2018 WL 4566565
    , at *43 n.39. Because we are
    “entitled to affirm on any ground appearing in the record, including theories not relied upon
    or rejected by the district court,” Scott, 
    328 F.3d at 137
    , and Mahdi offered no response to
    this argument in his reply brief, see Alvarez, 828 F.3d at 295 (reiterating that failure to
    engage in the adversarial process by responding to an argument ordinarily results in
    waiver), we will reach this issue here.
    101
    Code Ann. §§ 17-27-45, -90; S.C. App. Ct. R. 203(d)(3), 243. As such, the claim is
    procedurally barred. See Longworth, 
    377 F.3d at 447
    . And because Mahdi failed to provide
    any argument in his reply brief “demonstrat[ing] cause for the default and actual
    prejudice,” Sigmon, 956 F.3d at 198 (quoting Coleman, 
    501 U.S. at 750
    ), we affirm the
    district court’s denial of Mahdi’s Judicial Sentencing Claim.
    But even if we were to reach the merits of Mahdi’s argument, we discern no error
    in the district court’s rejection of it. At bottom, Mahdi maintains that the trial court erred
    in following the mandates of South Carolina Code § 16-3-20 rather than expressly
    determining whether he knowingly and voluntarily waived his Apprendi rights as set out
    in Ring and Blakely. Mahdi suggests the trial court improperly “imposed a sentence greater
    than the maximum [it] could have imposed under state law,” Opening Br. 73 (quoting
    Blakely, 
    542 U.S. at 303
    ), 43 based on its consideration of “additional” evidence and facts
    in aggravation, J.A. 1661, beyond those contained in Mahdi’s admission during his guilty
    plea. We disagree.
    As for his claim under Ring, we find no error in the PCR court’s conclusion that, at
    the time of Mahdi’s sentencing, the Supreme Court of South Carolina had already decided
    three cases expressly finding the death penalty statute constitutional because Ring is not
    implicated when a capital defendant pleads guilty. See State v. Crisp, 
    608 S.E.2d 429
    , 432–
    33 (S.C. 2005); State v. Wood, 
    607 S.E.2d 57
    , 61 (S.C. 2004) Downs, 604 S.E.2d at 380.
    Indeed, we reached the same conclusion years after Mahdi’s conviction. See Lewis v.
    43
    The death penalty is never required under South Carolina law, even with a finding
    of an aggravating circumstance. 
    S.C. Code Ann. § 16-3-20
    (B), (C).
    102
    Wheeler, 
    609 F.3d 291
    , 309 (4th Cir. 2010) (“[N]either Apprendi nor Ring holds that a
    defendant who pleads guilty to capital murder and waives a jury trial under the state’s
    capital sentencing scheme retains a constitutional right to have a jury determine
    aggravating factors.”). Thus, the PCR court’s determination that trial counsel could not
    have been deficient for failing to raise a meritless claim was not “so lacking in justification
    that there was an error well understood and comprehended in existing law beyond any
    possibility for fairminded disagreement.” Harrington, 
    562 U.S. at 103
    .
    Similarly, there is no reason to conclude that Blakely would somehow render
    Mahdi’s sentence unconstitutional. 44 In that decision, the Supreme Court stated that, under
    Apprendi, a judge may impose any sentence authorized “on the basis of the facts . . .
    admitted by the defendant.” Blakely, 
    542 U.S. at 303
    . And pursuant to 
    S.C. Code Ann. § 16-3-20
    (B), the death penalty may only be imposed upon a murder conviction when an
    aggravating circumstance is found. Here, Mahdi admitted to the two charged aggravating
    circumstances in his guilty plea: killing Captain Myers while in the commission of
    burglary and while in the commission of larceny with use of a deadly weapon. J.A. 1217;
    
    S.C. Code Ann. § 16-3-20
    (C)(a)(1)(d), (f). So no Blakely violation occurred in sentencing
    Mahdi to death.
    And while the trial court did not need Mahdi’s consent to judicial factfinding to
    44
    Mahdi did not directly present this issue in the state courts. Rather, he consistently
    framed the Judicial Sentencing Claim as being unconstitutional solely under Ring. Thus,
    the PCR court did not consider the arguments under Blakely he now raises in his § 2254
    petition. Nevertheless, because any claim under Blakely would fail on the merits, we will
    not address whether this additional aspect of the Judicial Sentencing Claim is
    independently procedurally barred.
    103
    sentence him to death, Mahdi nevertheless gave it. Blakely made clear that “[w]hen a
    defendant pleads guilty, the State is free to seek judicial sentence enhancements so long as
    the defendant . . . consents to judicial factfinding.” 
    542 U.S. at 310
    . As the record makes
    abundantly clear, Mahdi did just that.
    Before pleading guilty, trial counsel informed Mahdi that during sentencing “the
    State [would] have to put up [its] case and information and, of course, he[] [would] be
    allowed to put up information. The question [was] whether he [would] do that in front of a
    jury or whether he [would] do that in front of a judge.” J.A. 1179. In response, the trial
    court made clear that if Mahdi “plead[ed] guilty, the sentencing proceeding [would] be
    conducted before the judge.” J.A. 1183.
    During the plea hearing, the trial court went to great lengths to ensure Mahdi
    understood that if it were to accept his guilty plea, “the jury [would] have no role in [his]
    sentencing and the decision as to what sentence [he would] receive [would] be left solely
    up to [the trial court].” J.A. 1198. Acknowledging that he understood all of this
    information, Mahdi affirmatively gave up his right to a jury trial, see J.A. 1198 (“I’ve given
    up all of my rights to a 12 party jury.” (emphasis added)), and agreed to judicial sentencing.
    Mahdi’s consent to judicial factfinding during the plea hearing is also consistent
    with his trial attorneys’ testimony during the PCR hearing. As the PCR court observed,
    trial counsel testified that “Mahdi decided to plead guilty because [he] believed he had a
    better chance of receiving a life sentence from [the trial court] than from the jury he had
    selected.” J.A. 7636. The PCR court found this testimony credible, and Mahdi has
    presented no evidence suggesting this determination constitutes error, much less one that
    104
    is “stark and clear.” Elmore, 
    661 F.3d at 849
    . What’s more, “Mahdi offered no testimony
    to contradict trial counsel’s testimony on these issues.” J.A. 7636. Thus, the PCR court
    reasonably determined that “Mahdi wanted to be sentenced by [the trial court], not the jury
    he had initially selected and [e]mpaneled.” J.A. 7636. And Mahdi has failed to present
    “clear and convincing evidence,” Bennett, 842 F.3d at 322, that this determination was
    “sufficiently against the weight of the evidence,” Williams, 914 F.3d at 312.
    In short, the record leaves no doubt that Mahdi admitted to two aggravating
    circumstances in his guilty plea and knowingly and voluntarily waived any challenge to
    judicial factfinding by the trial court and that challenge would have been futile. Thus, the
    PCR court’s determination was neither “diametrically different, opposite in character or
    nature, or mutually opposed” to Ring or to Blakely, Vick, 
    233 F.3d at 216
    , nor “so lacking
    in justification that there was an error well understood and comprehended in existing law
    beyond any possibility for fairminded disagreement,” Harrington, 
    562 U.S. at 103
    . For
    these reasons, we affirm the district court’s denial of the Judicial Sentencing Claim.
    5. The Guilty Plea Claim
    Turning to Mahdi’s final IAC claim, he maintains that trial counsel were ineffective
    by “actively advising [him] that his guilty plea would be considered [a] mitigating [factor]
    at his judge sentencing.” Opening Br. 78. In response, the State asserts that Mahdi
    procedurally defaulted this claim. 45 We agree with the State.
    45
    As with the Jury Sentencing Claim, the district court expressly declined to address
    whether the Guilty Plea Claim was procedurally defaulted. See Mahdi, 
    2018 WL 4566565
    ,
    at *44 n.42. Like the Judicial Sentencing Claim, however, the State raised the procedural
    (Continued)
    105
    Mahdi did not raise the Guilty Plea Claim during his first state PCR proceeding.
    And the South Carolina Supreme Court rejected his efforts to do so during the second state-
    court PCR proceeding on procedural grounds. Thus, Mahdi has procedurally defaulted this
    claim. See Breard, 
    134 F.3d at 619
     (reiterating these grounds constitute a procedural bar).
    And because he made no effort to “demonstrate cause for the default and actual prejudice,”
    Sigmon, 956 F.3d at 198 (quoting Coleman, 
    501 U.S. at 750
    ), in his reply brief, we affirm
    the district court’s denial of Mahdi’s Guilty Plea Claim. 46 See Alvarez, 828 F.3d at 295
    (recognizing that failure to respond to an argument in briefing ordinarily results in waiver).
    III.
    For the foregoing reasons, we affirm the district court’s judgment in its entirety.
    AFFIRMED
    bar in its brief before this Court and Mahdi offered no response to this argument in his
    reply brief. As we are entitled to do, Scott, 
    328 F.3d at 137
    , we elect to reach this issue
    here.
    46
    Even if we were to reach the merits, we would still affirm for the reasons stated
    by the district court. See Mahdi, 
    2018 WL 4566565
    , at *45–47. To that end, we emphasize
    that, contrary to Mahdi’s efforts to contort the record, the trial court expressly considered
    his guilty plea as a “nonstatutory mitigating circumstance.” J.A. 1670. It merely gave the
    argument no “significant weight.” J.A. 1670; see also Lockett, 
    438 U.S. at 605
     (1978)
    (noting the importance of “an individualized decision” in capital cases). And, of course,
    there is a clear distinction between “no significant weight” and “no weight.” Thus, trial
    counsel’s advice was correct, meaning their performance was not deficient.
    106
    GREGORY, Chief Judge, dissenting:
    Mikal Mahdi does not claim that he is innocent. Rather, Mahdi asserts his humanity: his
    capacity for redemption. This appeal then raises questions, not of Mahdi’s guilt, but of whether
    it is too late to remedy trial counsel’s failure to show the many ways in which Mahdi was a
    product of a traumatic and tragic upbringing.
    In some ways, it is. Here, as in countless other cases, AEDPA’s often-unforgiving
    exhaustion requirement, 
    28 U.S.C. § 2254
    (b)(1), works with its merits review, 
    28 U.S.C. § 2254
    (d), to pose an insurmountable barrier for most of Mahdi’s claims. In my view, much
    like the majority’s, the district court did not err in granting summary judgment on Mahdi’s claims
    that his trial counsel were ineffective for (1) failing to challenge the constitutionality of 
    S.C. Code Ann. § 16-3-20
    ; (2) failing to advise Mahdi of the advantages of jury sentencing; or (3)
    incorrectly advising Mahdi that the district court considered his guilty plea as mitigation.1 Nor
    1
    Although I agree with these conclusions, I do not join in all of the majority’s
    rationale. For example, I disagree with the majority’s suggestion that an attorney is
    necessarily effective when she declines to raise a federal constitutional claim that is thought
    meritless by a state supreme court. See Maj. Op. at 52. The United States Supreme Court
    enjoys the final say when it comes to interpreting the United States Constitution. See
    Arkansas v. Sullivan, 
    532 U.S. 769
    , 772 (2001) (holding that a state supreme court may not
    interpret the United States Constitution to provide different protection than the Supreme
    Court’s federal constitutional precedents provide). I am not at all convinced that an
    attorney’s failure to preserve an issue that, while foreclosed by a state court, remains an
    open question of federal constitutional law will in all cases reflect a reasoned, strategic
    decision. But the focus of this opinion is highlighting how the district court erred in
    denying Mahdi a full opportunity to seek federal habeas relief.
    107
    did the district court err in holding that Mahdi procedurally defaulted many of his failure-to-
    investigate “subclaims.”2
    But, unlike the majority, I believe the district court unquestionably applied the
    wrong legal standard to Mahdi’s request for additional funding to hire an expert in race-
    based trauma. Without a valid ruling on Mahdi’s request for supplemental funding, it is
    premature to determine whether Dr. Hill’s testimony would allow Mahdi to present a
    “fundamentally altered” ineffective assistance of counsel claim based on trial counsel’s
    failure to present evidence of Mahdi’s race-based trauma. I would therefore vacate the
    district court’s grant of summary judgment on this subclaim. Finally, I would vacate the
    district court’s grant of summary judgment on Mahdi’s abuse subclaim and remand for an
    evidentiary hearing. New evidence of the physical abuse Mahdi suffered as a child
    fundamentally alters his failure-to-investigate claim, and genuine disputes of material fact
    preclude summary judgment on whether Martinez excuses the procedural default that
    resulted from Mahdi’s failure to raise this subclaim earlier.
    Because I differ from the majority in these respects, I respectfully dissent.
    I.
    The district court first erred when it denied Mahdi additional funding based on the
    wrong legal standard. The CJA creates various entitlements for capital defendants who are
    financially unable to mount their own defense. 
    18 U.S.C. § 3599
    (a)(1). Relevant here,
    2
    Mahdi raises four theories of ineffective assistance of counsel. He then divides
    one of those theories, trial counsel’s failure to investigate and present mitigating evidence,
    into sub-categories, labeling each a “subclaim.”
    108
    district courts may authorize defense counsel to obtain “investigative, expert, or other
    services [that] are reasonably necessary for the representation of the defendant.” 
    18 U.S.C. § 3599
    (f). In my view, the district court understood “reasonably necessary” to require
    more than precedent allows. See Ayestas v. Davis, 
    138 S. Ct. 1080
    , 1092–94 (2018).
    We typically defer to district courts’ funding decisions, only finding error when
    faced with an abuse of discretion. 
    Id. at 1094
    . But when a court applies the wrong legal
    standard, we’re called to withhold that deference, Koon v. United States, 
    518 U.S. 81
    , 100
    (1996)—a call that only rings clearer when the error impedes a defendant’s ability to
    challenge the most permanent sentence a state may impose. Heeding that charge, I would
    vacate the district court’s denial of Mahdi’s funding request and remand for the district
    court to apply the correct legal standard.
    A.
    Shortly after Mahdi petitioned the district court for federal habeas relief, the court
    appointed counsel and granted him $34,500 to retain a mitigation investigator and a social
    historian. 3 Mahdi filed an ex parte motion for additional funding to present “recently
    3
    Mahdi later realized he did not require the assistance of a social historian; he did
    not use any portion of the $12,500 allocated for that expert. There’s no question that
    imposing the death penalty with any measure of due process carries a high price tag.
    Federal courts must award capital defendants funding for all reasonably necessary services
    covered by 
    18 U.S.C. § 3599
    (a)(2). As the Supreme Court has admonished death is
    different. See Furman v. Georgia, 
    408 U.S. 238
    , 306 (1972) (Stewart, J., concurring)
    (“[t]he penalty of death differs from all other forms of criminal punishment, not in degree
    but in kind. It is unique in its total irrevocability. It is unique in its rejection of
    rehabilitation of the convict as a basic purpose of criminal justice.”); see also Gregg v.
    Georgia, 
    428 U.S. 153
    , 187 (1976) (recognizing that “there is no question that death as a
    punishment is unique in its severity and irrevocability.”).
    109
    discovered” evidence that would explain the severe impact of his past race-based trauma.
    J.A. 886; J.A. 29–33 (describing the recently discovered evidence that Dr. Hill would
    examine in-depth, distinguishing the recently discovered evidence from existing evidence,
    and explaining its impact on “address[ing] the multiple aspects of trauma that Mr. Mahdi
    experienced throughout his life.”); see J.A. 31 (“Dr. Hill will be able to examine the impact
    of these traumatic events and stress factors on Mr. Mahdi in the context of his unique
    ancestry and extrinsic and intrinsic racial identity.”). He argued that an expert’s assessment
    of his unique and severe race-based trauma would produce new evidence that was
    “compelling and warrant[ed] presentation as a Martinez claim.” J.A. 11. He then requested
    $25,000 to retain Dr. Hope Hill, 4 a professor and clinical psychologist, to develop and
    present this recently discovered evidence. 
    Id.
    At the court’s request, Mahdi then provided (1) a brief outline of the “recently
    discovered evidence” related to Mahdi’s race-based trauma; (2) a brief summary of how
    this information impacted the claims Mahdi sought to raise in the Amended Petition; and
    (3) a detailed description of the work to be performed by Dr. Hill to substantiate the
    estimated 90 hours of requested funding. J.A. 29–36. Mahdi argued that “the impact of
    the extrinsic trauma that [he had] experienced throughout his childhood [could] only be
    understood by looking at the intrinsic trauma that [he] suffered in relation to his racial

    Dr. Hill specializes in child development and social policy. J.A. 13. She has
    conducted extensive research on the development of at-risk youth and the effects of
    childhood exposure to violence, with a particular focus on Black youth. J.A. 21–24. Based
    on this expertise, Dr. Hill has qualified as an expert witness in courts across New York,
    Washington, D.C., Maryland, Pennsylvania, and North Carolina. J.A. 14–16.
    110
    identity.” J.A. 32. Dr. Hill could clinically detail the effects of that trauma, “systemically
    evaluat[ing] how Mr. Mahdi’s background, racial identity, and the trauma that he
    experienced emboldened his ‘survivalist’ mentality.” 5 
    Id.
    The district court nonetheless denied Mahdi’s request. At the time, the court was
    bound by our decision in Wright v. Angelone, 
    151 F.3d 151
    , 163 (4th Cir. 1998). In Wright,
    we held that § 3599(f)’s “reasonably necessary” standard only allowed courts to provide
    funds for “investigative, expert, or other services” when “a substantial question exists over
    an issue requiring expert testimony for its resolution and the defendant’s position cannot
    be fully developed without professional assistance.” 
    151 F.3d at 163
     (quoting Williams v.
    Martin, 
    618 F.2d 1021
    , 1026 (4th Cir. 1980)) (emphasis added). Understanding Wright—
    and, by extension, § 3599(f)—to impose a strict necessity requirement, the district court
    held that Mahdi failed to demonstrate that his Martinez claim “could not be fully
    developed” through the mitigation investigator and the social historian for which he’d
    5
    It is not clear what the majority means when it maintains that Mahdi failed to either
    “identify any themes that he intended to pursue through this supplemental funding request”
    or “forecast what Dr. Hill’s psychological report would contribute beyond the information
    his previously approved $34,500 in funding for a mitigation investigator and social
    historian had already yielded.” Maj. Op. 67, 66–68. Assuming, as I must, that these
    statements take on something other than their literal meaning, I read the majority as
    requiring greater specificity than what Mahdi’s supplemental funding request provided.
    But the problems with imposing such a demanding specificity requirement seem clear.
    First, the requirement finds no footing in the text of § 3599. Second, it runs counter to
    § 3599’s objectives. Section 3599 provides funding for services that are reasonably
    needed, but not yet available, to a petitioner. If Mahdi had access to the full scope of Dr.
    Hill’s clinical findings and assessments, he would not need additional funding to secure
    her expertise.
    111
    already secured funding. J.A. 40. In other words, the district court denied Mahdi’s request
    because he had not shown it was impossible to develop his claim without Dr. Hill.
    Eight months later, the Supreme Court unanimously rejected a similarly narrow
    construction of “reasonably necessary.” Ayestas, 
    138 S. Ct. at
    1093–95.
    B.
    Ayestas involved a challenge to the Fifth Circuit’s two-step approach to evaluating
    federal habeas petitioners’ funding requests. In the Fifth Circuit’s view, an applicant for
    § 3599(f) funding could not show that investigative services were “reasonably necessary”
    unless the applicant could (1) show that he had a “substantial need” for the services; and
    (2) supplement his funding request with a “viable constitutional claim that [was] not
    procedurally barred.” 6 Ayestas, 
    138 S. Ct. at
    1088 (citing Ayestas v. Stephens, 
    817 F.3d 888
    , 895–96 (2016)). But § 3599(f), the Court held, does not impose these burdens.
    Ayestas’s analysis begins and ends with the text of the statute: specifically, the
    phrase “reasonably necessary.” “Necessary,” Ayestas acknowledges, has two possible
    meanings: one strict and one ordinary. Id. at 1093. “In the strictest sense of the term,
    something is ‘necessary,’ only if it is ‘essential.’” Id. (citing Webster’s Third New Int’l
    Dictionary 1510 (1993) (something is necessary if it “must be by reason of the nature of
    things,” if it “cannot be otherwise by reason of inherent qualities”); 10 Oxford English
    6
    The majority makes much of the fact that the standard once used by the Fifth
    Circuit differs from the one that Wright imposed. See Maj. Op. 69–70. The question of
    course is not whether Wright’s standard is identical to the one Ayestas, 
    138 S. Ct. at
    1093–
    95 rejected, but whether it is consistent with the standard Ayestas, 
    138 S. Ct. at
    1093–94
    set forth. In my view, it is not.
    112
    Dictionary 275–276 (2d ed. 1989) (OED) (defining the adjective “necessary” to mean
    “essential”). The strict understanding of “necessary” fared poorly in the context of
    § 3599(f). Id. As Ayestas explains, it makes “little sense to refer to something as
    reasonably essential.” Id.
    Instead, Ayestas defines “necessary” in its ordinary sense—a term “used more
    loosely to refer to something that is merely important or strongly desired.” Id. Understood
    this way, § 3599(f) does not require a petitioner to “prove that he will be able to win relief
    if given the services he seeks.” Id. at 1094. Rather, the “statutory phrase calls for . . . a
    determination by the district court in the exercise of its discretion, as to whether a
    reasonable attorney would regard the [requested] services as sufficiently important.” Id. at
    1093 (emphasis added). The Fifth Circuit erred by requiring more. And because the
    district court understood Wright to impose a similar burden, it did too.
    By its own explanation, the district court denied Mr. Mahdi’s funding request
    because he failed to prove that he could not develop his Martinez/Trevino claim without
    the assistance of Dr. Hill. J.A. 40. Requiring that Mahdi prove that it was impossible to
    develop his claim without expert assistance was tantamount to imposing an absolute need
    requirement—a burden akin to, if not greater than, the “substantial need” requirement that
    Ayestas rejected. 
    138 S. Ct. at
    1093–94.
    The State contends that the fatal flaw in the Fifth Circuit’s two-part test was not the
    “substantial need” requirement, but the requirement that a petitioner present a viable
    constitutional claim that was not procedurally barred. Response Br. at 26. This argument
    doesn’t even appear to find favor with the majority. See Maj. Op. at 64–70. To be sure,
    113
    Ayestas rejected the Fifth Circuit’s “viable constitutional claim” requirement. Ayestas, 
    138 S. Ct. at
    1093–94. This requirement permitted district courts to deny a petitioner’s request
    for funding if her underlying claim was procedurally defaulted. But, as Ayestas explains,
    the rule did not account for Martinez v. Ryan, 
    566 U.S. 1
    , 17 (2012) or Trevino v. Thaler,
    
    569 U.S. 413
    , 416–17 (2013)—decisions that permit some federal habeas petitioners to
    present a substantial but procedurally defaulted ineffective-assistance-of-counsel claim by
    showing that state postconviction counsel was ineffective for failing to raise it. Sometimes,
    funding may be reasonably necessary to overcome that default. Ayestas, 
    138 S. Ct. at 1087
    ,
    1093–94. In those cases, where “funding stands a credible chance” of allowing petitioners
    to make that showing, “it may be error for a district court to refuse [it].” 
    Id. at 1094
    .
    But the egregiousness of the error at step two does not erase the error at step one.
    Ayestas explains in no uncertain terms that the difference between “reasonably necessary”
    and “substantial need” is a “problem”—a problem that was exacerbated by the “viable
    constitutional claim” requirement, but a problem no less. 
    138 S. Ct. at 1093
    . Nothing in
    Ayestas suggests that a “substantial need” requirement, standing alone, is consistent with
    § 3599(f). Even the Fifth Circuit understands Ayestas to prohibit both parts of its former
    two-part test. See, e.g., Nelson v. Davis, 
    952 F.3d 651
    , 666 (5th Cir. 2020) (“In Ayestas,
    the Supreme Court determined that this circuit’s requirement that petitioners demonstrate
    a ‘substantial need’ . . . was impermissibly more demanding than the ‘reasonably
    necessary’ standard established in [§ 3599(f)].”); Crutsinger v. Davis, 
    929 F.3d 259
    , 263
    (5th Cir. 2019) (“[Ayestas] held that the Fifth Circuit’s requirement that a movant show a
    ‘substantial need’ to demonstrate that funds were ‘reasonably necessary’ was not supported
    114
    by the text of § 3599”); Jones v. Davis, 
    927 F.3d 365
    , 373 (5th Cir. 2019) (“[Ayestas] held
    that the ‘substantial need’ requirement was more demanding than [§ 3599’s] requirement
    that the services sought be ‘reasonably necessary’ to a defendant’s post-conviction
    challenge.”). I, too, take Ayestas to mean what it says.
    C.
    The district court did not cure its pre-Ayestas error when resolving Mahdi’s post-
    Ayestas Rule 59 motion. Properly applied, § 3599(f) tasked the court with asking “whether
    a reasonable attorney would regard the [requested] services as sufficiently important.”
    Ayestas, 
    138 S. Ct. at 1084
    . Three principal considerations drive this inquiry: (1) “the
    potential merit of the claims that the applicant wants to pursue”; (2) “the likelihood that
    the services will generate useful and admissible evidence,” and (3) “the prospect that the
    applicant will be able to clear any procedural hurdles along the way.” 
    Id. at 1094
    .
    The district court’s Rule 59 order acknowledges Ayestas in form only, reciting the
    relevant standard but not applying it. See J.A. 909–11. The order lays bare the district
    court’s belief that Ayestas merely echoed the standard set forth in the district court’s
    original order:
    In denying Mahdi’s request, the court recited the applicable standard under
    § 3599 and focused on whether the requested services were reasonably
    necessary to adequately represent Mahdi and develop his anticipated
    ineffective assistance of counsel claim.[] Ultimately, the court found that
    counsel had not shown that the requested psychologist’s services were
    reasonably necessary in addition to the services of the mitigation investigator
    and social historian the court had already funded.
    J.A. 911 (internal citations omitted).
    115
    But, as discussed, it did not. The district court’s original order denying funding
    overstated § 3599’s “reasonably necessary” requirement and failed to discuss the three
    considerations that, as Ayestas explains, drive the § 3599 analysis. The Rule 59 order is
    similarly silent on how the Ayestas factors apply to Mahdi’s request. See J.A. 909–12.
    At most, the district court’s Rule 59 order impliedly considered the likelihood that
    the services Mahdi requested would generate useful and admissible evidence. See J.A.
    912. But even here, the analysis fell short because it misunderstood the services Mahdi
    sought. Noting that Mahdi’s mitigation investigator “had already gathered all of the
    pertinent factual information” and that Mahdi’s counsel “had already formed reasoned
    arguments as to why that information was critical to Mahdi’s mitigation presentation,” the
    district court found itself unable to see what “additional value” Dr. Hill could provide. J.A.
    912. The majority shares this view, insisting that the evidence that Dr. Hill would have
    provided was “already developed and presented to the PCR court.” Maj. Op. at 65–66.
    This reasoning either ignores or misapprehends the expertise that mental health clinicians
    bring to the table. They do not, like mitigation investigators, detail the facts of a person’s
    life in a historic sense. Compare J.A. 32 (explaining that Dr. Hill could discuss how the
    impact of Mahdi’s traumatic childhood was exacerbated by his complex racial identity and
    his father’s militant racial extremism), with J.A. 377 (detailing Dworkin’s skills and
    responsibilities as a mitigation investigator). And their opinions are far from the common-
    sense intuitions that may guide an attorney’s arguments absent a mental health expert’s
    guidance. See J.A. 13–21 (detailing Dr. Hill’s clinical training and experience); see also
    ABA Guidelines for the Appointment and Performance of Defense Counsel in Death
    116
    Penalty Cases 4.1, Commentary (rev. ed. 2003) (“ABA Guidelines”), reprinted in 
    31 Hofstra L. Rev. 913
    , 956–57 (2003) (“Counsel’s own observations of the client’s mental
    status, while necessary,[] can hardly be expected to be sufficient to detect the array of
    conditions [parenthetical omitted] that could be of critical importance.”).
    For the sake of illustration, consider the relationship of a physician to a claim that
    someone’s physical injury entitles her to economic damages. Lay fact witnesses can detail
    physical symptoms, describe limitations, and set forth relevant timelines. Attorneys can
    then take that information and argue that it warrants relief for their client. And still, many
    factfinders would find the presentation lacking, left only to wonder whether a medical
    doctor would agree with the attorney’s view of the injuries; whether there was a
    physiological explanation for the claimant’s symptoms; whether the pain she described
    aligned with a physician’s understanding of the disability. No one questions the need for
    medical experts when assessing the scope of physical injuries. That we find mental health
    experts unnecessary when defining the impact of past trauma says little about the need for
    that expertise, and much about us.
    * * *
    The standard that the district court applied—both in its original denial of
    supplemental funding and its Rule 59 order—is outdated and asks too much of petitioners
    seeking funds under § 3599(f). I would vacate the district court’s denial of Mahdi’s
    funding request and remand for the district court to correctly apply Ayestas.
    117
    II.
    I would also vacate the district court’s grant of summary judgment on two of
    Mahdi’s failure-to-investigate subclaims: (1) that trial counsel were ineffective for failing
    to investigate and present mitigating evidence of Mahdi’s race-based trauma, and (2) that
    trial counsel were ineffective for failing to investigate and present evidence of the
    childhood abuse he suffered at the hands of his father. The district court’s error in
    adjudicating Mahdi’s funding request precludes full review of his race-based trauma
    subclaim. Moreover, the district court erred in holding that Mahdi’s childhood-abuse
    subclaim did not present a “substantial” claim of attorney ineffectiveness.
    A.
    Because the district court applied the wrong legal standard to Mahdi’s request for
    funding, it is premature to review his race-based-trauma subclaim. The very reason Mahdi
    requested additional funding was to “develop and effectively present” the arguments for
    this subclaim. Opening Br. at 50. Mahdi explained that “[c]ounsel [] recently discovered
    evidence related to race-based trauma that [Mahdi] experienced during his childhood,” J.A.
    11, and that “Dr. Hill [would] be able to examine the impact of these traumatic events and
    stress factors on Mr. Mahdi in the context of his unique ancestry and extrinsic and intrinsic
    racial identity,” J.A. 31. Mahdi argued that Dr. Hill’s “in-depth examination of [his]
    lineage” would stand in stark contrast to the “very generally pieced together family
    biographies” that PCR counsel presented in the initial postconviction proceeding. J.A. 29.
    Stated differently, Dr. Hill’s testimony might have fundamentally altered Mahdi’s failure-
    to-investigate claim.
    118
    The majority maintains that Dr. Hill’s investigation, as proposed by Mahdi’s “vague
    representations”, see Maj. Op. at 70, would add nothing new that the other seven mental
    health experts had already evaluated. Specifically, the majority argues that Dr. Cooper-
    Lewter “had already conducted an extensive evaluation of Mahdi’s race-based trauma and
    family history.” Maj. Op. at 70 (referencing J.A. 2955–65). While it is true that Dr.
    Cooper-Lewter examined some of Mahdi’s family socio-history, Dr. Cooper-Lewter did
    not conduct an in-depth examination of Madhi’s family lineage of the kind proposed by
    Dr. Hill to understand how Mahdi’s inter-generational family trauma impacted him and his
    crimes. Compare J.A. 2955–64 (discussing Madhi’s grandparents and parents’ history)
    with J.A. 31–33 (proposing that Dr. Hill will investigate Mahdi’s “unique ancestry and
    extrinsic and intrinsic racial identity” and how these experiences “emboldened his
    ‘survivalist mentality.’”). Further, while I agree with the majority that Dr. Cooper-Lewter
    examined some of Mahdi’s race-based trauma history, Mahdi identified some key gaps in
    Dr. Cooper-Lewter’s investigation that are reasonably necessary to painting a complete
    picture of his psychological well-being leading up to this crime. For example, while Dr.
    Cooper-Lewter noted that Mahdi’s father was “anti-government,” constantly “raved about
    the ‘New World Order’ and ‘white folks coming to kill them[,]’ [and . . .] taught [Mahdi
    and his brother] how to shoot guns, fight with knives, and how to fist-fight and box.” J.A.
    2978. Mahdi noted Dr. Hill would fill in a gap of detailing how “he struggled with the
    inherent contradiction of his father’s black separatist beliefs and his father’s complete and
    119
    utter inability to provide for Mr. Mahdi’s most basic needs.” J.A. 32. 7 Dr. Hill’s recently
    discovered evidence is reasonably necessary in this case because it would have explained
    the impact of his race-based trauma and lineage on Mahdi’s psychological well-being, in
    context of his traumatic upbringing with his father, who indoctrinated Mahdi to have
    separatist, anti-government, and antagonistic views against whites. This is the evidence
    that jurors should have been appraised of to get a holistic view of all the stressors that
    Mahdi had leading up to his crimes. I disagree that “Mahdi did not present any meaningful
    argument . . .” and I disagree with the district court’s incorrect application of the legal
    standard. Maj. Op. at 71 (emphasis added).
    Had the district court applied the correct legal standard—with the correct
    understanding of the requested services—and granted funding to retain Dr. Hill, Mahdi’s
    claim would stand on much different footing. Without Dr. Hill’s testimony, Mahdi’s only
    additional evidence of race-based trauma is Dworkin’s affidavit. To be sure, this affidavit
    details some of the facts underlying Mahdi’s race-based trauma in a way that PCR counsel
    7
    Dr. Cooper-Lewter’s general descriptions of Mahdi’s family history are distinct
    from Dr. Hill’s. At best, Dr. Cooper-Lewter stated that: “Shareef would constantly tell
    Mikal what he did wrong, but would provide him with no solutions. While he lectured on
    work ethic, he had no job and made no attempt to work. The family lived on public
    assistance, what his grandmother provided, and ultimately what Mikal could steal. While
    Shareef would spend hours lecturing Mikal about stealing being wrong, he would then
    “thank him” and keep the stolen property or funds.” J.A. 2980. Dr. Cooper-Lewter also
    described Mahdi’s upbringing before committing his first offense, at age 14, as “Mikal
    described it though, he was basically on his own, stealing to survive and continuing to get
    the preaching/lectures from Shareef, followed by Shareef keeping the property and
    thanking him.” J.A. 2981. Thus, while Dr. Cooper-Lewter provided a descriptive history,
    Dr. Hill, according to Mahdi, would connect his family’s intergenerational history of race-
    based trauma to his criminal history.
    120
    did not. See J.A. 367–69, 517 (“While PCR counsel may not have traced Mahdi’s lineage
    all the way back to 1648, as Mr. Dworkin did, they did present evidence regarding Mahdi’s
    family’s history, racial views, and significant experiences with racism, and the very
    segregated nature of their environment.”). But at its core, Dworkin’s affidavit, like the
    PCR testimony, reflects only the existence of segregation, racial animus, and self-loathing
    in Mahdi’s lineage—not their effects. J.A. 367–69. It strengthens but does not change
    “[t]he heart of the claim.” Gray v. Zook, 
    806 F.3d 783
    , 799 (4th Cir. 2015); see also
    Vandross v. Stirling, 
    986 F.3d 442
    , 451 (4th Cir. 2021) (explaining that to assert a new
    claim, a petitioner must do more than “merely strengthen[] the evidence presented in the
    state PCR hearing”).
    In my view, Dr. Hill’s testimony was likely to do what Dworkin’s affidavit cannot.
    We don’t know what we don’t know. But Dworkin’s affidavit gives me good reason to
    believe that, aided by Dr. Hill’s expertise, Mahdi would have had a compelling argument
    that his race-based trauma subclaim was “new,” Wise v. Warden, 
    839 F.2d 1030
    , 1033 (4th
    Cir. 1988), and that Martinez excused the procedural default that resulted from Mahdi’s
    failure to timely exhaust this claim, see Maj. Op. at 66 (citing Vandross, 986 F.3d at 450
    (4th Cir. 2021) (noting that one of the requirements for invoking Martinez is that “it is
    likely that no state court will hear the prisoner’s claim”)). Because the district court’s
    Ayestas error precludes meaningful review, I would vacate the district court’s grant of
    summary judgment on the race-based-trauma subclaim and remand for further
    proceedings.
    121
    B.
    The district court also erred in holding that Mahdi could not overcome the procedural
    default on his subclaim that trial counsel were ineffective for failing to uncover and present
    evidence of his childhood abuse. This subclaim is new and presents a substantial claim of
    ineffective assistance.   The only remaining issue is whether PCR counsel performed
    deficiently by failing to raise this claim in the state postconviction proceedings—an issue
    that, on this record, should not have been resolved with summary judgment.
    1.
    To begin, this subclaim is a new one. A federal habeas petitioner presents a new and
    unexhausted claim when he submits evidence which (1) “was not presented to the state
    court,” and (2) “places his case ‘in a significantly different and stronger evidentiary posture
    than it was when the state courts considered it.’” Wise, 
    839 F.2d at 1033
    . New evidence,
    even when favorable, will not always change a claim at its core. Gray, 806 F.3d at 799. But
    when a federal habeas petitioner “presented no evidence to the state courts to establish the
    existence of fact X, the claim will be fundamentally altered by the new evidence presented
    to the district court.” Winston v. Kelly, 
    592 F.3d 535
    , 550 (4th Cir. 2010).
    The question of whether Mahdi has presented a new claim “is necessarily case and fact
    specific.” 
    Id. at 549
     (quoting Morris v. Dretke, 
    413 F.3d 484
    , 491 (5th Cir. 2005)). Here,
    Mahdi’s first cousin, Nate Burwell, IV, recently revealed “substantial insights into the family
    dynamics,” recalling “Mikal and [his brother] being beaten by their father as children.” J.A. 317.
    Years later, Nate can “hear them screaming still.” 
    Id.
    122
    PCR counsel did not interview Nate or present any evidence that Mahdi suffered
    severe physical abuse as a child at the hands of his father, Shareef. In fact, all evidence was
    to the contrary. See, e.g., J.A. 2240 (“[Shareef] was always doting on his sons and always
    very, very affectionate with them.”), 2243 (“[Shareef] couldn’t institute discipline. There
    was no discipline and he was real soft with his discipline . . . he was not heavy-handed at
    all.”), 2541–42 (Q: Isn’t it true that there was no evidence in this case that Mr. Mahdi was
    physically abused by his father? A: . . . In the medical reports there was [an] incident where
    he fell off his bike and hurt his leg and another time his arm, but as far as physical violence
    from his father, no.”). The only evidence of Shareef’s physical abusiveness related to Vera
    and Nancy. J.A. 2285–86 (“[Vera] told me Shareef raped her on her wedding night.”), 2298
    (“[Vera] was covered in bruises from head to toe and she said Shareef beat her up. She was
    trying to see the children and he beat her up.”), 2403 (“[Mahdi] then saw his father kidnap
    and beat his mother and he saw his father also beat his own mother.”).
    Trial counsel also failed to interview Nate or present any evidence of the extreme
    physical abuse Mahdi suffered as a child. Looking only to the picture of Shareef that trial
    counsel painted, a factfinder would believe that Shareef was specifically not physically
    abusive toward his children. Given that Mahdi “presented no evidence” on this issue in both
    the PCR and trial courts, I see no way to view this subclaim as anything but new. See
    Winston, 
    592 F.3d at 550
    .
    The majority does not dispute that defense counsel, at both the trial and PCR stage,
    painted Shareef as a loving and doting father—affectionate—who particularly favored
    Mahdi. Maj. Op. at 29. Rather, it simply considers allegations of severe childhood abuse to
    123
    be “new bits of evidence” rather than “critical evidence that makes [Mahdi’s] claim both
    stronger and significantly different.” Maj. Op. at 89 (quoting Moore v. Stirling, 
    952 F.3d 174
    , 183 (4th Cir. 2020)). By doing so, it views the strength of childhood-abuse evidence as
    mitigating evidence much differently than the Supreme Court, 8 the South Carolina trial
    court, 9 the State’s trial counsel, 10 and the State’s PCR counsel, 11 among others—myself
    included.
    2.
    Notably, a new claim often poses as much of an obstacle for petitioners as it does an
    opportunity. In failing to raise and exhaust his abuse-based theory of ineffectiveness, Mahdi
    procedurally defaulted it, saddling himself with the task of identifying a basis to excuse that
    default. Owens v. Stirling, 
    967 F.3d 396
    , 409, 421–22 (4th Cir. 2020). As onerous as that
    burden may be, Martinez v. Ryan paved a way for him to carry it. 
    566 U.S. 1
    , 14 (2012).

    See, e.g., Williams v. Taylor, 
    529 U.S. 362
    , 398 (2000) (indicating that the “graphic
    description” of a “childhood[] filled with abuse and privation . . . . might well [] influence[ a]
    jury’s appraisal of [a defendant’s] moral culpability”); Penry v. Johnson, 
    532 U.S. 782
    , 796–
    803 (2001) (rejecting jury instructions because they failed to provide an adequate vehicle for
    jurors to consider childhood abuse as mitigation evidence); Eddings v. Oklahoma, 
    455 U.S. 104
    , 114–16 (1982) (noting that the “beatings by a harsh father” were “particularly relevant”
    as mitigating evidence for young defendants).

    J.A. 1283–84 (emphasizing that Mahdi did not suffer physical abuse), 1631

    He was never physically abused”), 1695–96 (“In reviewing Ms. Hambrick’s [sic] testimony,
    what is absent is any reference to physical abuse”), 1696 (“There is absolutely no evidence
    of [] abuse”).

    J.A. 2491 (emphasizing that Mahdi did not suffer physical abuse); 2541–42 (same).

    As the majority notes, Martinez requires petitioners to show that: (1) their underlying
    ineffective-assistance-of-trial-counsel claim is “substantial”—that is, it must have “some
    merit” under the governing ineffective-assistance-of-counsel standards; (2) they were not
    represented or had ineffective counsel during the state PCR proceeding; (3) the state PCR
    proceeding was the initial review proceeding; and (4) state law required the prisoner to bring
    the claim in the initial-review collateral proceeding. Trevino, 569 U.S. at 423; see also Maj.
    Op. at 74. It’s undisputed that Mahdi’s claim satisfies Martinez’s third and fourth elements.
    To satisfy the first two elements, Mahdi need only show that there was “some merit” to his
    claim that he was prejudiced by constitutionally deficient trial counsel, and that PCR counsel
    “performed deficiently, under the first prong of Strickland, by failing to exhaust the
    underlying ineffective-assistance-of-trial-counsel claim.” Owens, 967 F.3d at 423.
    Our assessment of counsel’s performance under Strickland is “highly deferential.”
    Id. at 412. But that deference is not without limits. Stokes v. Stirling, 
    10 F.4th 236
    , 246 (4th
    Cir. 2021); Williams v. Stirling, 
    914 F.3d 302
    , 313–16 (4th Cir. 2012). The American Bar
    Association Guidelines for the Appointment and Performance of Defense Counsel in Death
    Penalty Cases indicate “[a] ‘well-defined norm’ . . . ‘that investigations into mitigating
    evidence should comprise efforts to discover all reasonably available mitigating evidence.’”
    United States v. Runyon, 
    989 F.3d 716
    , 731 (4th Cir. 2020) (quoting Williams, 914 F.3d at
    313).
    Capital defense counsel are therefore deficient when they “fail[] to investigate and to
    present substantial mitigating evidence to the sentencing jury.” Williams, 
    529 U.S. at 390
    (2000). To be sure, “strategic choices made after thorough investigation of law and facts
    125
    relevant to plausible options are virtually unchallengeable.” Wiggins v. Smith, 
    539 U.S. 510
    ,
    521 (2003) (quoting Strickland, 
    466 U.S. at
    690–91). “[A]nd strategic choices made after
    less than complete investigation are reasonable precisely to the extent that reasonable
    professional judgments support the limitations on investigation.”        
    Id.
       But a cursory
    investigation does not “automatically justif[y] a tactical decision with respect to sentencing
    strategy.” Id. at 527. Courts must look further, “consider[ing] not only the quantum of
    evidence already known to counsel, but also whether the known evidence would lead a
    reasonable attorney to investigate further.” Id.; see also id. at 534 (counsel performed
    deficiently by abandoning investigation after discovering that the defendant had alcoholic
    parent, spent childhood in foster care, lacked consistent schooling, and suffered from child
    hunger); Williams, 
    529 U.S. at 396
     (counsel performed deficiently by failing to uncover and
    present mitigating evidence at sentencing) (citing 1 ABA Standards for Criminal Justice -
    4-4.1, Commentary, pp.4–55 (2d ed. 1980)).
    a.
    The district court appears to have rejected Mahdi’s Martinez claim based on its
    conclusion that the underlying IAC claim did not have even some merit. See J.A. 518. The
    district court recognized the significance of childhood abuse as mitigation evidence, 
    id.
    (citing Porter v. McCollum, 
    558 U.S. 30
    , 43 (2009)), but nonetheless felt that it could not
    fault trial counsel’s failure to uncover it. J.A. 518. Why? Because the “two people who
    would have known about the abuse—Shareef and Mahdi—[failed to] disclose[] this
    information.” 
    Id.
    126
    I cannot join in reasoning that requires so little of capital defense counsel. Common
    sense should have led trial counsel to suspect that Mahdi and Shareef might deny or
    understate past abuse. “One of the things that we know is that abused children–even abused
    adults–tend to cling to their abuser.” J.A. 2424; see also ABA Guidelines 10.7, Commentary
    (“Obtaining [sensitive] information typically requires overcoming considerable barriers such
    as shame, denial, and repression, as well as other mental emotional impairments from which
    the client may suffer.”). And those who have perpetrated abuse are likely to deny it for
    different, but equally obvious, reasons. Let us not forget that someone once accused Shareef
    of physical abuse—he then tied her to a tree and whipped her legs with the buckle end of a
    belt. J.A. 2925.
    Even if common sense didn’t lead trial counsel to uncover Mahdi’s abuse, the
    evidence should have. Williams, 914 F.3d at 314–16. Trial counsel knew that Shareef was
    incredibly violent to vulnerable people in his life. At the sentencing phase, they elicited
    testimony from Hammock that Shareef had abused his wife so severely that she left her two
    children to escape it. J.A. 1600. Hammock also testified that Shareef had “issues that
    prohibited him from being a good father.” J.A. 1608. She explained that Shareef was
    “extremely troubled,” J.A. 1598, prone to “outburst,” J.A. 1610, and “not really able to
    function well,” J.A. 1600. The postconviction proceedings reveal that trial counsel also
    knew that violent outbursts were a hallmark of Shareef’s parenting. J.A. 2819, 2823, 2898.
    In contrast, there is no evidence that trial counsels’ decision not to investigate or present
    mitigating evidence of childhood abuse was a strategic one. Nor is there any evidence that
    127
    they believed evidence of childhood abuse would in some way harm Mahdi’s defense or
    undermine their theory of the case.
    Trial counsel ignored both common sense and unrefuted evidence of Shareef’s
    impulsiveness, violence, irrationality, and poor parenting. They ignored the signs that some
    of the other adults in Mahdi’s life likely towed the line between discipline and uncontrolled
    physical force. See J.A. 2774, 2811. And they ignored the very likely possibility that the
    violence Mahdi exhibited as a child reflected the violence he saw and experienced firsthand.
    Instead of following these “red flags” to their logical conclusion, Williams, 914 F.3d at 315,
    trial counsel decided that Mahdi had not been abused as a child because both the abuser and
    the abused denied it. Surely, we do not set the bar so low. See Porter, 
    558 U.S. at
    40 (citing
    Rompilla v. Beard, 
    545 U.S. 374
    , 381–82 (2005)).               A defendant’s “fatalistic or
    uncooperative” behavior “does not obviate the need for defense counsel to conduct some sort
    of mitigation investigation.” 12 
    Id.
     (citing Rompilla, 
    545 U.S. at
    381–82); see also J.A. 2424.
    12
    The district court cited our decision in DeCastro v. Branker, 
    642 F.3d 442
    , 456
    (4th Cir. 2011) in support of its contrary view. Mahdi v. Stirling, No. 8:16-3911-TMC,
    
    2018 WL 4566565
    , at *36 (D.S.C. Sept. 24, 2018). In DeCastro, we reviewed a state PCR
    court’s decision that trial counsel were not ineffective for failing to investigate and present
    mitigating evidence that the defendant had withheld pre-trial but disclosed following
    sentencing. 
    642 F.3d at 456
    . Because this claim was “adjudicated on the merits,” we
    reviewed the state court’s decision through 
    28 U.S.C. § 2254
    (d)(1)’s rigorous standard and
    concluded that it was not unreasonable. 
    Id. at 449, 456
    . Even setting aside the factual
    differences between these two cases, the differing legal standards precludes DeCastro from
    being a helpful analog. I cannot overstate the difference between our review of an
    ineffective assistance of counsel claim through the lens of § 2254(d)(1) and our review of
    the ineffectiveness that undergirds a Martinez claim. When petitioners invoke Martinez to
    excuse a procedural default, they necessarily present claims of ineffectiveness that have
    not been presented to state courts nor adjudicated on the merits. Martinez, 
    566 U.S. at 11
    .
    District courts evaluate those claims de novo, unconstrained by § 2254(d)(1). Gray, 806
    (Continued)
    128
    Nor does the peculiar demeanor of a defendant’s family members free capital counsel
    from uncovering all reasonably available mitigation evidence. And yet, the record does not
    reveal what, if any, efforts trial counsel undertook to find favorable mitigation evidence once
    they grew frustrated with those who knew Mahdi best. Indeed, it is difficult to imagine
    counsel showing more disrespect for a former client’s family (and most likely source of
    mitigation evidence) than trial counsel demonstrated at Mahdi’s state postconviction
    hearing. 13 At one point, lead trial counsel testified:
    So, we had grandmother who wanted to save the family name. We had [an
    uncle] who is the dean of men frying fish and he just didn’t care. He was proud
    of the fact he identified [Mahdi to the police]. We had [an aunt] who still
    harbored resentment about the fact that [Mahdi’s brother] attempted to burn
    down her house and you had [another uncle] who thought it was funny that
    [Mahdi] was threatening to kill himself.
    J.A. 2820–21. Later, upon labeling Mahdi’s family “dysfunctional,” lead trial counsel
    lamented, “There are many [B]lack families like that.” J.A. 2829.
    F.3d at 789. Thus, a holding that a state court did not act unreasonably in rejecting a
    petitioner’s ineffective-assistance-of-counsel claim should not be understood to mean that
    counsel was not, in fact, ineffective.
    13
    See, e.g., J.A. 2814 (“When we arrived in the yard [Nathan] drove up. He was
    slightly overweight and he was inside a Mazda Miata two-seater . . . . So he drove up in
    this Miata and he was slightly overweight. He walked in the house and we introduced
    ourselves to him, but he had an attitude . . . . He is in this car that’s too small. He is the
    Dean of Men. He walks inside of the house. He has an attitude toward us. This is a guy
    who’s probably in his late to early 50’s and he’s living with his mama . . . .”), J.A. 2819
    (“[Shareef] is preaching black power every day, empowerment of the black man, but he
    can’t hold a job. He can’t pay his bill.”), J.A. 2822 (“[Nancy] was older and she was
    confused . . . . Each time you talked to her she would sit down [with] . . . some little
    pamphlets and booklets about different people in the family and what they had
    accomplished. It was almost as if she wanted to be absolved of all responsibility and she
    wanted the world to know that [they were] still good people.”).
    129
    Counsels’ belief that the adults in Mahdi’s life were “dysfunctional” should have
    caused them to seek information from another generation of family members—Mahdi’s
    cousins—not to abandon his search altogether. See ABA Guidelines 10.7, Commentary
    (“Barring exceptional circumstances, counsel should seek out and interview potential
    witnesses, including, but not limited to . . . . members of the client’s immediate and extended
    family.”); id. (detailing the importance of “[a] multi-generational investigation” that
    “extend[s] as far as possible both vertically and horizontally”). Had they done so, trial
    counsel would have easily uncovered the same key witness federal habeas counsel found:
    Nathan’s son, Nate Burwell, IV.
    Instead of investigating further, trial counsel tapped a social worker and prison
    adaptability expert as Mahdi’s only mitigation witnesses. Counsel gave Hammock sole
    responsibility for conveying the trauma of Mahdi’s childhood experience—she presented a
    sanitized version of Mahdi’s life, concluding that Mahdi had “a rather chaotic and different
    kind of childhood.” 14 J.A. 1597. But, as this Court has recently explained, the need to
    14
    A rather chaotic and different kind of childhood. To be clear: Mahdi was raised
    by a single parent after his mother—upon suffering severe and sustained physical and
    sexual abuse—left. Vera left without her two young boys because Shareef threatened to
    kill them if she tried to take them. As Mahdi was growing up, Shareef withheld access to
    formal schooling. In the summer after Mahdi’s second-grade year, Shareef used him as
    bait to see Vera. When Vera arrived, Shareef abused her, threatened to kill her in front of
    Mahdi, then took her to the woods to assault her. When Shareef’s mother learned of this
    and confronted him, he bound her to a tree and whipped her legs with a belt. Eventually,
    Shareef took Mahdi out of public school to “homeschool” him. Shareef’s curriculum
    involved teaching Mahdi how to shoot guns so that he would be ready when the “white
    folks” came to get them; teaching Mahdi how to stab people; and indoctrinating Mahdi
    with an ideology of racial and religious supremacy. This is not a “rather chaotic and
    different kind of childhood,” see J.A. 1597; it is “profound and chronic trauma that [is]
    (Continued)
    130
    present the “profound and chronic trauma” of someone’s childhood is at its highest when the
    alternative is to put forth “almost no mitigation presentation at all.” Stokes, 
    10 F.4th 236
    ,
    253 (4th Cir. 2021). In my view, there is at least some merit to Mahdi’s claim that trial
    counsel were deficient for cutting their investigation short.
    Moreover, this deficiency was likely prejudicial. Trial counsel did not present any
    lay witnesses during the sentencing phase of Mahdi’s capital proceedings. And Hammock’s
    brief rendition of Mahdi’s family history did very little to humanize him when considered
    alongside his serious crimes. See J.A. 1597–1612. As the majority’s thorough recitation of
    the facts illustrate, Hammock’s testimony was vague, only hinting at the chaos and transience
    of Mahdi’s living circumstances; Shareef’s “inability . . . to parent appropriately and
    correctly,” J.A. 1597; and the “confrontational” relationship between Shareef and other
    members of the family that led to Mahdi’s isolation and radicalization, J.A. 1601. These
    abstractions did very little to deepen the trial court’s understanding of “the individual behind
    the aggravating evidence.” Stokes, 10 F.4th at 252 (4th Cir. 2021) (citing Allen v. Woodford,
    
    395 F.3d 979
    , 1000 (9th Cir. 2005)).
    As much is reflected in the trial court’s sentencing decision.             The court’s
    consideration of Mahdi’s “turbulent and transient childhood and upbringing” as a mitigating
    circumstance spans four sentences. J.A. 1669. It first notes that there was “no reference to
    physical . . . abuse suffered by the defendant” and that “defendant’s father . . . continually
    about as extreme as any child can experience.” Stokes, 10 F.4th at 253 (holding that capital
    counsel performed deficiently when they conveyed profound and chronic trauma as merely
    a “difficult upbringing” and “struggles growing up”).
    131
    expressed great care and concern for [Mahdi’s well-being].” J.A. 1669–70. Then, viewing
    Hammock’s testimony as a whole, the court concludes that Mahdi’s upbringing was simply
    “less than ideal” but bore no relation to his criminal conduct. J.A. 1670. In the end, the trial
    court gave Mahdi’s upbringing “no weight” as a mitigating circumstance. Id.
    Evidence of childhood abuse is always “especially mitigating, and its omission is thus
    particularly prejudicial.” Andrews v. Davis, 
    944 F.3d 1092
    , 1117 (9th Cir. 2019). Against
    this backdrop—where trial counsel’s mitigation presentation had no bearing on the
    factfinder—evidence of childhood abuse would have been particularly powerful. In my view
    there is at least some merit to Mahdi’s argument that he was prejudiced by trial counsel’s
    deficient mitigation presentation.
    b.
    For many of the same reasons, there is a good reason to believe that PCR counsel’s
    failure to investigate Mahdi’s childhood abuse and challenge trial counsels’ effectiveness
    was deficient. That said, I would not reach that question because genuine issues of material
    fact preclude judgment on the issue.
    As discussed above, the question of whether an attorney’s performance was deficient
    turns in large part on whether their decisions were strategic. Wiggins, 
    539 U.S. at 521
    (quoting Strickland, 
    466 U.S. at
    690–91). Even though the district court proceeding was
    parties’ first opportunity to create a record for why PCR counsel made the decisions it did,
    the district court denied Mahdi’s request for an evidentiary hearing. J.A. 529–30. A perhaps
    unintended result of this is that the State did not produce evidence or argue that PCR
    counsel’s failure to investigate and present evidence of Mahdi’s childhood abuse was a
    132
    strategic choice. Instead, it sought judgment on this claim on other grounds—namely, that
    the abuse subclaim was not new and that, even if it were, trial counsel were not ineffective
    for failing to raise it. See J.A. 117–18. But, as discussed above, both of these premises are
    incorrect.
    In contrast, Mahdi presented evidence that state counsel’s failure to uncover Mahdi’s
    childhood abuse was not at all strategic. In his opposition brief, Mahdi argued that “PCR
    counsel . . . . had no strategic reason . . . for failing to interview witnesses uncovered by
    Federal habeas counsel who witnesse[d] abuse at the hand of Mr. Mahdi’s father.” J.A. 339–
    40 (citing Dworkin Aff., Ex. 1). Dworkin’s affidavit then gave substance to this argument,
    identifying the witness that PCR counsel overlooked and previewing the relevant testimony.
    J.A. 370–71. Viewed against Stirling’s silence on the issue, this evidence—while limited—
    should have been fatal to Stirling’s motion. See Fed. R. Civ. Proc. 56(a), (c)(1)(A).
    I would vacate the district court’s judgment on this subclaim and remand for the
    district court to hold the evidentiary hearing that Mahdi requested.
    III.
    The district court’s standard for denying Mahdi’s funding request was inconsistent
    with the directives set forth in 
    18 U.S.C. § 3599
    . And its grant of summary judgment
    unduly discounted the gravity of Mahdi’s abuse subclaim. Because the majority overlooks
    these errors for the sake of finality, I respectfully dissent.
