it's not really surprising that the religions that have prospered the most (financially, population, etc.) are the ones that have created the most terrible punishments and amazing rewards for their followers. like, heaven and hell are really modern christian beliefs. they didn't really exist in the OT outside of some terrible translations. like, really look at the references to hell and heaven in the bible and what books they originate from. dante painted what people picture as the christian hell more than the bible. dante and the christian leaders preaching fire and brimstone.
