The madman who opened fire on a packed Brooklyn train — hitting 10 people and igniting terror underground — blamed racism for his planned-out attack before a Brooklyn federal judge sent him to prison for the rest of his days.

Frank James, 64, sat emotionless in a tan jumpsuit as Judge William F. Kuntz hit him with a life sentence on 10 counts — saying the bloody April 12, 2022 rampage had been fueled by nothing but “pure evil.”

“I could feel bodies pile up on top of each other,” one of the victims recalled about the horrifying attack — which seriously injured commuters and petrified the city.

James — who before the shooting had a history of spewing racist hate in videos posted online under the moniker “Prophet of Doom” — delivered a bizarre nearly half-hour-long speech to the court, in which he said racism in US health services and “ghetto mental health facilities” had failed him and “poor people.”

He compared his plot to attack innocent commuters to the death of Jordan Neely, the homeless man with a long history of mental illness who was allegedly placed in a fatal chokehold by ex-Marine Daniel Penny on a Manhattan train in May.

“I, like that young man, was a mental health consumer,” James said. “I didn’t scream out for help — I made the mistake of reaching out and asking for help.”

James also quoted from books he said he’d read over the last 17 months at the Metropolitan Detention Center, such as Harriet Beecher Stowe’s “Uncle Tom’s Cabin” and other racially-focused works to detail the struggle of blackness in America while saying his actions were “shining a light on certain services of the city that I received.”

“I alone am responsible for that attack — it had nothing to do with race, creed, color or sexual orientation,” James insisted. “They in no way deserved to have what happened to them.”

James, who said he “wouldn’t bust a grape in a food fight,” sat impassively through impact statements from five of his victims — who recounted the terrifying experience of riding the subway that day.

One victim — identified only as “CT” — in a written statement said she survived the September 11 terror attacks after missing an alarm, but wasn’t as lucky last April.

Assistant US Attorney Sara Winik read the mother’s account about how she was excited to be back for her first day in the office after working remotely during the pandemic — and how she had a friendly conversation with James before hearing “pop-pop-pops” of gunfire.

“I could feel bodies pile on top of one another,” CT said in the statement.

Another survivor, “BK,” who said anxiety overtakes his life after the attack, recalled seeing a man being shot in front of him on the N train in Sunset Park.

“I saw a dark hole in his back,” said the victim. “I could see so much blood leak down from his back.”

“I realized I was going to die,” he later said.

Another victim, “LC,” said he’s spent $12,000 on e-scooters since the attack to avoid taking the subway.

Fitim Gjloshi, who previously spoke to The Post about the day he came face-to-face with James, was so overcome by emotion during his speech that he broke down in tears before exiting the courtroom.

“I don’t blame him — he just needs help. I could forgive him,” Gjloshi said before walking away.

Prosecutors had asked for James to get 10 concurrent sentences of life imprisonment for the “careful and prolonged planning” that went into the attack, adding that he’d only stopped shooting his semi-automatic Glock pistol because it jammed, according to court papers.

James’ defense attorneys argued that he should be sentenced to 18 years in prison because he’s been “tormented by lifelong paranoid schizophrenia” leading up to the attack. They argued that James is “not evil” but “very, very ill” — and deserved mercy for the “horrifying” crime.

James pleaded guilty to 10 counts of committing a terrorist attack or other violence against a mass transportation system — one for each gunshot victim — in January this year.

“My intention was to cause serious bodily injury to the people on the train,” James admitted at the time of the hearing, while insisting he hadn’t meant to kill anyone.

The judge also sentenced him to an additional 10 years for an 11th count for discharging a firearm during an act of violence.

Federal prosecutors said James set off smoke bombs on a crowded Manhattan-bound N train in Sunset Park before he squeezed off 32 shots.

James had traveled to Brooklyn from an Airbnb in Philadelphia and boarded the subway car with a smoke bomb, a gas mask and a Glock 17 handgun that he legally purchased in Ohio, prosecutors have said.

When the train moved between the 59th Street and 36th Street stations, James’ smoke bomb went off, cops said.

He disguised himself as an MTA worker — wearing a yellow hard hat and orange reflective vest — while hiding behind a mask when he started firing, strategically positioning victims at the opposite end of the train car to create a “kill funnel” so no one could stop him, according to prosecutors.

The shooting victims ranged in age from 16 to 60. Others also suffered from smoke inhalation or other injuries that occurred on the 36th Street station platform.

Images from the attack showed a platform covered in bodies and blood.

The cold-blooded creep had begun planning the attack as early as 2017, when he started collecting weapons, prosecutors have said.

James had left a digital paper trail detailing his plans for the attack. His online searches included “MTA,” “New York,” “transit” and “stops on the N train” — and foreshadowed the eventual chaos in videos posted to social media, according to the feds.

The madman bizarrely called Crime Stoppers on himself after a day-long manhunt following the shooting.

In court Thursday, Winik, the prosecutor, said James was “deliberately shooting fish in a barrel” during the attack, “but the barrel was a New York City subway car and the fish were human beings.”
