The worse thing about the concept of gods is that some people believe in them. Then, they start getting their marching orders from a mythical being. What happens is their subconscious starts whispering to them, and they fantasize this to be the "voice of God." If they are in power, as Bush was or any number of Islamic fundamentalists are, or if they are the pope, they start issuing orders based on their imaginings, thinking it is actually God talking to them.
"What's that, God? You want me to launch the missiles? Oh, well--you're call!"
