Eliminating the Puritans, Mao, and Lenin would be unnecessary because I got rid of the people that inspired them. For that reason it may not be necessary to get rid of Crowley if I just got rid of all the occultists that came centuries before. It would be easier to just prevent the brain injury that turned him into what he was rather than killing him or preventing his parents from ever meeting. I’m sure the Marquis de Sade would still be torture-murder-raping women and children though.Agreed, although I'd add Emperor Constantine I, Mao Zedong, the Puritans, and Lenin to that list and maybe spare the Marquis De Sade and Aleister Crowley and bring them back to the present alongside Bill Hicks, GG Allin, and Tim Wilson and sign them up for Kiwi Farms.
King Henry VIII should most likely go on my list. Diocletian, Nero, Ghengis Khan, and William Sherman definitely should.
