Well, imagining my perception of the universe has been completely wrong and God, heaven and hell actually do exist... it kinda depends on what you would need to be allowed in heaven. If being a nice person who has never commited a crime is enough to go there, I'm in. But if the whole not believing in the existence of heavens boss thing would be important I'd probably have to spent quite some time in burglatory.
It would actually be pretty well possible that if the afterlife would exist it would actually be a corrupt place where the rich buy their place in heaven and the poor, no matter how good they lived, would go to the overpopulated hell. Or South Park could have been right, meaning that only Mormons go to heaven (but hell's isn't actually such a bad place).
