I'm bored as fuck and collect manifestos so here's every single one made by a murderer that I'm aware of/that has been released (Elliot's and Palmeter's are already in this thread OFC so look above)
in order
Christopher Dorner (LAPD anti-police shooter, rare uncensored edition)
Chris Harper-Mercer ("My Manifesto" self hating mutt spergs over how much black men suck, also gay satanism)
Seung-Hui Cho (Doesn't have a title. Raw schizophrenia)
Pekka-Eric Auvinen (Finnish columbiner)
Ethan Miller ("The Downward Spiral of Ethan Miller", retarded Columbiner, this one was posted on fucking Wattpad btw)
Elliot Rodger ("My Twisted World", see above)
Matthew Harris ("DEATH sentences", see above)
The Racist Ones
Anders Breivik ("2083", warning it is 1500+ fucking pages)
Dylann Roof ("rtf88")
Brenton Tarrant ("The Great Replacement")
John Earnest ("An open letter")
Patrick Crusius ("The Inconvenient Truth")
Payton Gendron ("Yeah", this one is just Tarrant's basically)
Stephan Balliet ("DoKumentation", note: he actually had two manifestos one of which is much closer to an 'actual' manifesto instead of catgirl BS, but was never released. anyway have you ever wanted to see the worst homemade gun instructions ever? don't try at home, you'll blow yourself up. there are also documents blaming Mark Mann for the shooting and a catgirl poster but I didn't include those)
Juraj Krajcik ("A call to arms", author was groomed/possibly ghostwritten by terrorgram feds)
Ryan Palmeter ("A White Boy Summer To Remember", see above)
Non-English Ones
Random brazilian kid who attempted a mass stabbing whose name I can't remember ("O Pós Modernismo E Suas Consequências Na Nossa Nação")
Karl Foyer (schizo statement by man who shot up mosque claiming the French feds threw him in the back of a vehicle, shoved a flag up his ass, and made him do the shooting), if you want translation just ask I have one
Dmitry Vinogradov (Russian Misanthrope rants about why he hates society, this was originally an rtf file but i had to convert it reeeeee)
Most of these are very, very retarded.
Edit: im retarded I forgot about Marc Lepine
