There's actually a loophole. If you have faith in Jesus, who didn't even have faith in God, even though he is God, you get away with doing whatever you want and all is A-OK when you croak.

That's hardly surprising though when you consider that ignorance and poverty breed crime and religiosity in equal amounts.
