Here's an interesting thought: Assuming that the force being in balance means equal numbers of Jedi and Sith, and that Palpatine helped bring about that balance with the clone wars, Palpatine was actually doing the will of the Force. Of course, that's if my take on the balance of the force is correct. I've heard several takes on it, but I like that one the best. Other people don't because it leaves to much room for Palpatine to be a sympathetic character. It's like the Judas betrayal. Some one was going to do it; it was just a question of who.
