"I have trouble seeing how an omnipotent god could have created the universe that way, unless the omnipotent god favors injustice, which is how we arrive at the Gnostic conception of reality."

Which is close to what I believe, tentatively. There are two universes interpolated into each other, one of "hell" and one of "heaven"...

On the other hand, I'm not sure I believe in "justice" - it's kind of a shaky concept. I think the best we can aim at is a marginal fairness going forward. But there's no way to fix the past. All we can do is remix it in such a way that the dead serve the living instead of the other way around...
