I've been thinking for a while how i would kill myself. (Not that i want to btw)

But i believe that if i had like a year left to live because i had cancer or something like that, i would go on a spree to take as many lifes as i could with me to the grave. Like the guys that went through Columbine or Jokela was really not that bad. They were crazy as hell but they will be remembered a long time, and if i would die anyway i should want to "Go out with a big bang" =I

Then ofcourse, it would be really meen to the people i killed and there families... Maybe ill have to reconcider.
What do you think would make someone remembered?
