A lot of cultures believe the afterlife to be a pretty ominous place. You're floating around in endless darkness while still being able to feel hunger and thirst. What you do in life has no effect on where you go or what happens when you get there because it's the same for everybody. The only real difference is how people in your life feel about you. If they care then they will regularly leave behind offerings to you so that your spirit won't continue to feel hunger pains or thirst. Otherwise you'll be stuck in darkness while experiencing endless pain.
