I'm fucking sick of all of these needy, emotional, sexual being all around me. Every last human being should die, including all of you. Maybe if I was the last person alive I would finally feel some peace.
It's technically impossible for you to kill off 7 billion people. Seeing you're a misanthrope and comes here I doubt you have the charisma to become the new fuhrer, and even if you did you'd still never be able to kill off that many, since this will never happen you'd probably reach Breivik levels at best before you either got arrested or shot. So all in all the only real choice is to kill yourself. Have a good tune.
