God is imaginary. The modern Christian version of this fictional creation is the only version that I know of that has this inconsistency. Not even every Christian believes god to be all-good, so it's really not a very good argument against the existence of god. Were I a Theist all I would have to say is 'My God is not omnibenevolent' and the entire thing falls apart. I think the only purpose to this way overused argument is to cheese off certain Christians.
