[Batman] Does the Joker actually WANT to Win? What'd happen if he did?

 Hi guys;
 I've seen a  couple of things that have got me thinking, the times the Joker doesn't kill Batman, cause it wouldn't be fun, does he WANT to win? Does he have an 'end game plan'?

What'd actually HAPPEN if he did win?

His end game is to make Batman kill him.  Thus proving that everyone's moral code can be "broken".  In order to get Batman to kill him, he gets to do all sorts of messed up things to Gotham.  The Joker won't kill Batman, because that's the only way that Joker can really "lose".
