The shooter who was killed after he gunned down a Montreal police officer in a shooting in a Jewish neighborhood that left a local rabbi dead and another policewoman wounded left behind a twisted, 104-page manifesto.

The gunman, identified by Quebec’s coroner as 25-year-old Seth Hatfield, raged in the rambling document against Zionists, capitalism, law enforcement, feminism and the pornography industry, among other grievances, according to the Montreal Gazette, which reviewed the manifesto.

“Be unflinching, go forth, and KILL THEM ALL!” he said at the conclusion of the sick missive. 

In the manifesto, Hatfield blames feminism, liberalism and capitalism for the “situation of terrible loneliness, isolation, and social degradation” he believes men face, the Guardian reported.

He also sought through terror to create a “new order” that would limit freedoms for women, according to the Gazette.

The shooter also reportedly named “the headquarters of international pornography companies” and those who “actively promote pornography to the public” as targets.

Following the shooting, the Gazette reported that broken windows were visible in the building that houses Pornhub’s parent company, Aylo, which is in the Côte-des-Neiges neighborhood.

“We are aware of recent media reports about yesterday’s shooting, including reports discussing a possible connection to Aylo and Pornhub,” Aylo told the outlet in a statement. “The investigation remains ongoing, and we will not speculate on motive or share unconfirmed information.”

In a statement to The Post, Aylo said: “We want to express our deepest condolences to the families and loved ones of Const. Mohamed Lamine Benredouane and Michael Moshe Mizrahi, as well as to the Montreal Police Service (SPVM) and everyone affected by this horrific tragedy.

“The safety of our community is our highest priority, whether that be our dedicated employees, our online community, or the city of Montreal, which a large part of our team proudly calls home. Though our city was struck by tragedy, we want to express gratitude to the first responders who bravely protected us and ensured that none of our employees were physically harmed by yesterday’s events.”

Hatfield described influential Zionists and the headquarters of all corporations with ties to Zionism among his dozens of “valid potential Class A targets,” according to the Gazette.

Other prime targets Hatfield named include international real-estate companies, private equity firms, elite bankers, politicians, healthcare and oil CEOs, plastic surgeons, and cryptocurrency moguls.

Residents in the city’s Côte-des-Neiges neighborhood — a heavily Jewish section of the city with several kosher restaurants, a Chabad, Jewish schools, and Jewish community centers surrounding the area — were told to take shelter around 12:30 p.m. Monday after a gunman was spotted prowling the area, the outlet reported.

Harrowing footage of the shooting shows a pair of officers engaging the gunman in camouflage clothing, who rushes at them with a rifle.

Constable Mohamed Lamine Benredouane, 34, was killed during the shootout. A female officer, who has yet to be identified, was wounded in the attack. 

Rabbi Michael Moshe Mizrahi, a member of the local Jewish community and the Chabad MADA center, was identified by Quebec MNA Monsef Derraji as the bystander who had been killed.

“He loves to celebrate together with everyone,” MADA community member David Kakon told Chabad News. “Someone who is always smiling, always has a kind word for someone else. Loves his family, loves Israel, and loves being a Jew. We are praying.”

It’s unclear whether Mizrahi, 68, was fatally wounded by crossfire during the shootout between police and the gunman.

Officials declined to identify Mizrahi or comment on the manner of his death late Monday, stating the investigation remains in its early stages.

“It’s a tragedy. It’s a nightmare,” Montreal Police Chief Fady Dagher told reporters in the aftermath. 

Hatfield is believed to have acted alone.

The Post has reached out to SVMP and the Bureau des Enquêtes Indépendantes (BEI), which is now leading the investigation, for additional information.
