I got this one cofty. Because an all-powerful AND an all-loving creator wouldn't put innocent people in harm's way.
If he's all powerful that means he can save innocents, if he's all-loving that means he's motivated to save innocents. When motive is combined with ability in that regard, then no innocent people would be getting killed.
But they are getting killed. Which means either God can't save all the innocent people, or he's refusing to do it. Making him either ineffectual, or kind of a jerk.
Though, as I have stated, I believe the most probable situation is simply that no deity exists at all.
