I think that every sentient being except maybe psychopaths are subject to a higher morality. I think that if God exists, even he is probably subject to it. The aspects of the morality are the following:
>compassion
>the golden rule
>retribution if you violate the golden rule
>some kind of law against violations against basic sentient or human dignity

I think that if God has violated a key factor of this rule, he will be subject to punishments himself, probably from himself. This is inevitable considering he's an eternal being.

I don't like Satan, and thus will probably serve God in the apocalypse, if possible.
