I live because I want it to be worthwhile. Not because I think God is going to send my to 'Hell' or whatever if I do not. Why would I want to become a criminal? That's just stupid. The afterlife means nothing to me, and most likely never, ever will.

It wouldn't change anything. Regardless what comes after you die you still have to live with yourself and the consequences of your actions. Karma is a bitch you know.
