My idea of Heaven isn't a great cloudy land where every dead dude goes, but your own personal paradise. Everyone would perceive heaven differently. Example, my Heaven would have no spiders to speak of because there is nothing in this world that rattles my bones worse (that I've yet experienced). But what about a scientist who'd dedicated his life to the study of spiders, who never once hurt one? Our paradises couldn't coincide...
By the same logic, Hell for me would probably include regular torture involving spiders. The claustrophobic pits of magma and flame among thousands of the condemned sounds pretty bad, too, but I'm sure mental punishment would also be used. I don't especially want either eternal burning or eternal Fear Factor.
One thing I wonder is what happens to
masochistic people in Hell?
