I finally figured out where hell came from.
You know when you're dealing with a problem, usually disagreement among persons and you know you can't resolve that problem but it is a problem that could theoretically be solved, and a disastrous end is in sight? It's that nervousness you get in that moment, that focused incapacitating moment.
Even before God created humans, his foresight, combined with the free will he gave to man, produced that moment in him. Hell was the (unforeseen?) byproduct.
So that's where it came from, I'm not sure why God decided to stick with it. Hell, maybe he didn't stick with it, I guess his decision on that is up to the theologians.
