Heres a link that will explain every single one of your questions, and more if you continue to research. :)
I think this is my hint to join in.
Let me answer your question with a question. Why do you think God is so bad because of hell, when he went through the worst emotional and physical pain possible to make sure that we would not have to go there?
There have been things in there that have been proven wrong, like the creation story so wouldn't that put everything else up for grabs?
Depends upon your interpretation.
Cute. I'll tell Anne Frank that when I meet her in hell. That'll cheer her up.
Look, cleaning up after your own damn mess is something kids learn by the age of eight. It's not anything special.
Erm, how was it GOD'S mess?
We're the ones who sinned, it was OUR doing. We did not have to.
Oh. Sure. Because creating a race of self propogating, sentient, extremely curious monkeys, a fiery inferno for them to go to if one of them makes so much as one mistake, and a way for them to make said mistake in the first place (all while knowing the goddamn future, no less) is a really good idea.
Not according to Verty. :/
