Everyone thinks an omniscient, omnipotent being must share our morals. They use evil as proof against such a being. However, it is just as likely that God is evil or simply doesn't care about us. Do you care about an ant you walk by. You would not kill it or help it. Its so insignificant who cares. Perhaps God feels the same about us.
Sometimes I think we were created to teach God morality. An omniscient and all powerful being will not have ethics because it cannot understand finite things such as altruism, ( God can never self sacrifice because he always wins).
Perhaps the incarnation can be seen as God tapping into finite power. God became man so he could experience courage etc.
Actually I am an agnostic. But I think speculations facilitate understanding.
You are expressing some deistic beliefs, and I think deists are not meant to answer this question, because simply it's irrelevant to them...
My question is directed to traditional theists -if that describes them correctly-, the ones that believe in a god who cares, like christians, muslims, so on...
