Hmm, I'm pretty sure there wasn't a hell in the early christian bible, either, Arden. Added later to add incentive for people to not sin, I believe. Can't prove that, of course, but it's inline with other stuff that has been added/removed/changed in the Bible over the years.
Personally, I believe that the afterlife (heaven, if you want) is what you make of it. If you believe you'll go up to into the clouds, stand in front of some gate with St. Peter there, that's what'll happen. Or if you believe that death is it, there's no more...that's what will happen. Purely subjective.
As to hell, I don't really believe in a hell. I do believe in a sort of...hmm...limbo, I suppose would be the best way to describe it. The movie
What Dreams May Come describes it pretty well -
"[Hell] is your life gone wrong". It was put for suicides, but I believe it's for anyone that's done something they've felt is totally wrong. I don't believe, however, that one would be stuck there for eternity. I believe once one admits or accepts what they've done wrong, they'll move on, so to speak. There's a short story by Clive Barker that illustrates what I believe pretty well, too, though I can't remember the name of it. Basically, it's about a dream a guy keeps having, of a place. In this place there's a lot of
places all mixed together. The guy doesn't see anyone there at first, but after a while, he figures out that all of these places are murder scenes, and stuck in them are the people that have committed the murder(s) there. At first glance he never noticed the people there, because they're pretty still most of the time. At one point, he
does notice somebody moving. He sees a man leave one of the places there, and go racing out into the desert (err, there's a desert surrounding all of the jumbled-up places). The man drops some weapon (a knife, I think) as he's going, and suddenly he disappears in a flash of light...and the guy dreaming hears a baby's crying as he does. So, pretty much, the place is a kind of purgatory, where the murderers are trapped until they come to terms with what they've done, after where they're reborn to try again.
BTW, Arden, reincarnation is a religious belief where you keep being born over and over again until you don't sin at all (pretty much). I'm thinking you mean more of just being reborn over and over again, which isn't exactly what reincarnation is about.
