i will not touch the questions but ur post does remind me of a South Park episode that was wise at the end:

Jesus was going to be crucified by South Park unless God appeared yadi yadi yada. He was all sad and thought God didn't love him cause he would not help him, when he realized this: if every problem is solved for u then u lack free will. If God stopped every killer they would lack free will.

A perfect world for u could be hell for another.

Well I am an atheist myself, but I liked that South Parks whole morale, I had never thought of it that way. Although not believing in a god because the world isn't nice is completely absurd. I cna only say that I do not believe in a God and all that stuff because there is no evidence for him and that I don't really believe in magic.
