The Joker
The more I think about the guy, the more I think that he actually doesn't think about his actions because he doesn't have to. If you've ever played Freecell, and played it well, and for a long time, there eventually comes this wonderful clarity where you don't have to think about your moves eighteen steps in advance and what will happen to this row if you do this. Stuff just comes together. The same can be said about my life. I don't think about it, but it comes together and it works. Sure there are parts that I struggle with, but by and large, they work. I think the Joker is smart enough to figure out what he wants and how to get it subconsciously, so he only need to react to what happens, not act and think about his actions.
