God is cruel

"Cruel" here is being used in a moral sense (it's immoral to be cruel). But if we have no objective morality, then our moral judgments are subjective and hence meaningless as far as being proofs of anything.So if you say "The fact that atheists go to hell is an immoral act on the part of God," you have uttered a mere subjective statement which proves nothing one way or another about God.If there is no God, then our morality is subjective.You would need an objective morality, provided by God, to prove that God is cruel.

No, all I've done is eliminate what might be called "the moral argument against God."I haven't proven anything in regard to God's existence. All I've done is say that we cannot judge God morally if our morality is subjective.

But if it's not objective, it's useless as a proof of anything. It's just a personal preference we have. We can't prove God is cruel if we have no objective knowledge of what constitutes cruelty.

Actually, there's a hidden argument here. Note this from the OP. What he's really saying is that if God existed he would be cruel (so He doesn't exist). But if our morality is subjective, then we can't make objective moral judgments.So we can't prove God doesn't exist by calling him cruel.
