Well, not God pulled Dean out of Hell but Castiel. So he's got the power too, whether God commanded him to or not.

I'm not saying there are no angels, so Good vs. Evil would just as well work with angels and demons. I fear that Kripke will go there when he smartest move would be not to. They've been SO vague on whether there is God and Lucifer, and I liked that. To now have "God's Will" in there...it's awkward. And it throws off the balance.
