I'm an atheist, so I can't say "god loves you so don't do it", but I can still say "don't do it, because there's nothing in the afterlife and that would be really boring." Death is nothing more than an eternal curse of boredom. So, savor your life while you've got it, and go out and do some crazy shit.

Pick up a hooker or something. Go to college if you haven't already. Hell, start building Gundam models. That'll eat up so much of your time you won't even think about doing anything shitty.
