Do the concepts of morals apply to an all powerful being? I would argue that they do.

Does a being who is almost omnipotent, but can't create coca-cola, have moral responsibility? What about one who is can do anything except change its own form from that of a human? Someone who can do anything that Jesus is reported to have done? Someone who is just like me, but can levitate? Me? Where does it end? The answer is simple: everyone has some degree of moral responsibility.

The more powerful and intelligent you are, the more responsibility you have.

I guess another argument from above is "Why do we get to judge God?" I ask: "Why not?"
That is, we don't hold the military beyond reproach, even though it is immensely powerful. Our parents' actions aren't inherently moral, even though they created us. Why should God be any different?
