God is limited in the way that He can never go against Divine Nature.<quoted text>
What is your objective criteria that murder etc is wrong? If God owns the world how could it ever be wrong for Him to do what He deems fit?
If you want to show that the acts of God in the Bible are wrong then you are going to have to show an objective standard-law that is binding on God.
Secondly, since God created the world He can do anything He pleases. No different than when you own something. You can do anything you want with it.
I don't think you really believe in God.
