Luigi Mangione, accused of attempting to assassinate the UnitedHealth CEO, detailed his motives and admiration for the Unabomber in a disturbed journal, as disclosed in court documents.

The disturbed writings were uncovered in a small red spiral notebook that he had in his backpack when he was arrested last year.

The 27-year-old heir to a real estate fortune was aware that attacking Brian Thompson, 50, during an investors conference in New York City on December 4 would create significant headlines, he noted in his writings.

“The news headline speaks volumes: Insurance CEO killed at annual investors conference,” Mangione remarked, according to documents provided by Manhattan District Attorney Alvin Bragg.

“It conveys a greedy bastard that had it coming.”

The Ivy League graduate fumed over the healthcare industry in the deranged ramblings as he said it, “extracts human life force for money.”

Mangione appeared to muse over planning a mass casualty attack and mentioned the Unabomber Ted Kaczynski, who killed three and hurt 23 others by mailing bombs.

“So say you want to rebel against the deadly, greed-fueled health insurance cartel,” the notebook reads.

“Do you bomb the HQ? No. Bombs=terrorism.”

He went on to agree with some of Kaczynski’s worldviews, but said that bombing wasn’t a good method to connect with “normies.”

“For example, Ted K makes some good points on the future of humanity, but to make his point he indiscriminately mailbombs innocents,” Mangione wrote.

“Normies categorize him as an insane serial killer, focus on the act/atrocities themselves, and dismiss his ideas.”

Mangione ended the narcissistic notes with an eye-rolling apology, but insisted that he had no choice but to allegedly gun down the dad of two.

“I do apologize for any strife or trauma, but it had to be done,” he wrote.

“Frankly, these parasites simply had it coming.”

DISTURBING ‘INTENT’

In the filing, Bragg claimed that the unhinged writings were key to pinning the crime on Mangione, as he said, “The shooting itself speaks volumes of the defendant’s intent.”

“If ever there were an open and shut case pointing to a defendant’s guilt, this case is that case.

“Simply put, one would be hard pressed to find a case with such overwhelming evidence of guilt as to the identity of the murderer and the premeditated nature of the assassination.”

Mangione is facing six state charges and four federal charges over Thompson’s shooting death, and Attorney General Pam Bondi wants prosecutors to seek the death penalty.

She made the decision to “carry out President Trump’s agenda to stop violent crime and Make America Safe Again,” she wrote in a statement in April.

“The murder was an act of political violence.” she wrote.

Investigators honed in on the suspect after a pulse-pounding five-day manhunt, which allegedly saw Mangione escape Manhattan and flee to Pennsylvania.

He was eventually caught at a McDonald’s after a worker recognized him from surveillance images as he chowed down on hash browns.

Mangione is set to next appear in court on June 26 for the New York state case.
