for sake of argument, if God 'did' choose to set up hoops for Himself - would that be wrong?

since God is by definition the sole and final arbiter on all things moral and ethical, then the world He sets in motion for His Will and Glory would by all accounts be totally justifiable; since the only One who might Justify it is Himself, no?

Putting aside the finer details of your argument; even if everything you said about Him was true, would there be anything you could do about it other than submit?
