By saying that an omnipotent, creator of the universe and all it contains can only do evil incidentally and can't create it intentionally.
Might as well be a Rachni drone awaiting orders from the queen!
I never said that he can’t create evil intentionally, he just doesn’t do that because he’s omnibenevolent.
The guy who drowned entire civilizations in a fit of pique? If ya say so!
The bible acknowledges his alleged behavior by acknowledging that he's capable of evil, you reduce him to an unthinking automaton with no choice other than to be benevolent.
In any case it isn't keeping with the way the fictional character of God is described. Petty, inconsistent, tyrannical, cruel and vain.
That's entirely consistent with a character who can create evil and completely out of character for an omnibenevolent being. You're a fiction author who pens fantasies about wizards and magic too, you should know this stuff!
