Stephen Law's "Evil God" Argument

In a recent debate with William Lane Craig, Stephen Law proposed an interesting argument in defense of atheism. He provided many examples of "good" in the world and from those concluded that an evil God does not exist. He then challenged Craig to show how one can believe that a good God can exist when one believes that an evil God does not exist. In a very simple form, the argument looks like this:


1. An evil God does not exist.
2. An evil God and a good God are the same
3. Therefore, a good God does not exist
4. Craig's God is a good God
5. Therefore, Craig's God does not exist

At this time, I'm not going to focus on the first premise (although it will play a part). I think that Craig handled it adequately in the debate (Randy Everest at Possible Worlds addresses the concerns with the premise and Craig's responses in his analysis of the argument). However, premise 2 is the one that did not receive much attention from Craig and where I think that he could have also shown the argument's weakness. I want to quickly go over a few observations about the second premise.
