Let the Joker Win

In Batman: The Killing Joke we find the Joker trying to make one simple little point: The only difference between normalcy and insanity is just one bad day.  He goes to great lengths to prove his point by kidnapping the Commissioner and shooting his daughter.  And through the course of events I started to realize that maybe The Joker is right?  After all, Batman is clearly insane.  Why else would he dress up as a flying rodent and hide in the dark?

And before I could put the pieces together myself I see the Joker deduce something clearly obvious to him: Batman once had a bad day too.  Needless to say I was disheartened when that infernal Batman foiled Mr. J’s plans.  And people can say what they want about the ending, I for one like to believe it was simply too adversaries with mutual respect for one another sharing a good laugh.
