Notorious imprisoned NYC sex fiend Peter Braunstein is making a case against state parole reform, warning of a bloodbath if someone like him is ever set free.

“All I’d do is kill people,” Braunstein told The Post in an unhinged, scribbled letter where he promises to murder Democrats and “monsters” if he is ever released.

Braunstein — a one-time fashion writer who made international headlines in 2005 when he impersonated a firefighter, sexually tortured a former colleague he was obsessed with in her Chelsea apartment, and then evaded a police manhunt across several states for two months — warned woke Albany reforms will only let more dangerous lunatics like himself out on the streets.

“If I was let out tomorrow I’d be reincarcerated in short order because all I’d do is kill people,” he wrote in the June 12 letter to a Post reporter.

“Prison is where I deserve to be,” wrote Braunstein, who is serving 18 years to life in Wende Correctional Facility in upstate Alden.

The ex-Women’s Wear Daily fashion critic offered a laundry list of targets: “Democrats (traitors), trannies (monsters), that Piker guy, ” he wrote, referring to Hasan Piker, a far-left influencer and streamer.

“The list is endless.

“The U.S. right now is lost, baby, lost,” he wrote. “I’m so glad I’m not out there.”

The Post wrote to Braunstein, 62, asking what he’d do if he was granted his release under two new parole-reform bills under consideration in Albany.

The Elder Parole bill would let violent criminals dodge their minimum sentences, regardless of how heinous their crimes, and be granted early parole hearings after they’ve turned 55 and served 15 years of their sentences. 

A second measure, the Fair and Timely Parole bill, would require the state Parole Board to release convicts regardless of the severity of their crimes unless they are a “current” danger to the public.

Braunstein had a parole hearing last year and was denied because he didn’t show up for it, but is set to reappear before the board next year.

Critics fear lunatics like him might be sprung if the bills become law.

“I think you’re going to see a lot of murderers released. . . . murderers and sex offenders, and assuredly some criminals who have committed the most heinous crimes in New York. . . . I’m talking about guys like [John Lennon’s murderer] Mark David Chapman and the Son of Sam [serial killer David Berkowitz],” said former Parole Board Commissioner and state Sen. Marc Coppola, who resigned from the board in September.  

“And the difference between the two bills is some of them will actually be released earlier than their minimum, and that alone, I think, is very very wrong,” he said. “It’s disrespectful to the victim and the victims’ families.”

Had Braunstein shown up for that missed hearing in 2025 — and attended a second hearing — he’d likely walk free as the bills are written, Coppola said.

But Braunstein insists he doesn’t want to get out.

“The only way I’m leaving prison is in a body bag,” Braunstein wrote in the three-page missive written in blue ink on yellow legal-pad paper.

And both he and the public are better off, he said.

“This may seem hard to believe and is certainly not the typical inmate position, but when I committed my crimes in 05 I was done with the world and I have consistently maintained that position ever since,” said Braunstein.

“Prison isn’t just where I deserve to be, it’s where I want to be because it separates me from a world I loathe.”

The failed playwright has been busy behind bars, revealing he has written a sick book about incest. 

“I wrote a mini-novel called Infinite Wishes about a teenage girl who has an ambiguous sexual relationship with her father and goes on to acquire special powers,” he wrote.

“Sure, I’d love to see it published but that’s unlikely, but it’s still gratifying as a personal accomplishment.”

On Halloween night 2005, Braunstein set a fire outside the 36-year-old victim’s apartment and pretended to be a firefighter in a ruse to get her to open the door. 

Once inside, he chloroformed the woman, stripped her to her underwear, and bound and sexually assaulted her for more than 13 hours, videotaping the savage abuse.

“I was terrified,” the victim, a former writer for W magazine, testified at his 2007 trial.

“He told me I was lucky I was alive,” she testified, remembering waking up bound by her wrists and ankle to her bed — wearing only her pink underwear and a pair of bronze stilettos he had found in her closet.

Even then, Braunstein fancied himself a killer.

“He told me he’d already killed a few people,” she said. “He said he had a list of people who were going to die.”

Before leaving, he scrawled a mocking note on her mirror: “Bye — Hope things turn around for U soon.”

Braunstein was convicted of kidnapping, sexual abuse, robbery and burglary. 

Once he completes his sentence, Braunstein has to serve another 23 years in Ohio for kidnapping a male psychiatrist while he was on the lam for two months.

He was finally captured in Tennessee, stabbing himself in the neck in a failed suicide attempt as cops closed in.

In his letter to The Post, Braunstein said he still thinks about the victim, whose name was never made public, “from time to time.”

Still, he continued to show no remorse for his crime and outrageously claimed “I kind of bonded with her while I held her captive, kind of like Stockholm Syndrome in reverse.”

In another appalling claim, he wrote that the cruel crime was “an act of self definition.”
