Seeker, an allpowerful god could correct the adverse combinations of hormone levels and brain wiring that drive some human beings to prey on others. A person who is unable to control their own mind and actions due to flaws in their brain/upbringing/soul/character/God-given-whatever has less free will than one who was created without any biological compulsions to harm others.
An all-powerful god who withholds rain from starving nations and flood others, creates disease-causing organisms and parasites to torment innocent animals and babies, demands that people slaughter their neighbors and steal their land, and allows children to be abused by his own priests in his own house of worship is either insane or completely unethical, IMO.
If God does not want us to be slaves, why do you suppose that he told the Israelites that owning slaves was OK?
I don't blame God for the problems of the world. I blame the people who believe in him.
