Specifically, his speech to Harvey Dent about how he's an agent of chaos. SF Debris dismisses it as him just lying, but I dunno. While it is true he's lying about the organizational efforts he uses to pull things off, I seriously think he was being real - or as real as this Joker ever gets. Because this was one of his goals from the start - make people turn on each other, show them how nasty we can get, and upend the system. And to corrupt Harvey Dent, the White Knight of Gotham, into that would accomplish those goals as much as getting Batman to break his "one rule." Also, I wanna add, I don't really think the Joker had "plans" per se, so much as he had several going on, and was a master of improvisation, like the way Palpatine was, so in a sense, he was correct - he had no plans, but was just making things up as he went along. I mean, take the armored car chase. I really believe he wanted to capture Dent, not kill him, so that he could make Batman or the cops make the same choice. Whether or not Dent is Batman doesn't affect any of these, but it does lead to more or less the same end - corrupt people to his way of thinking. I call it a campaign of "organized chaos." It's a pure contradiction, but then, that's the Joker's nature.

I think Alfred summed it up himself. "Some men are not interested in anything logical like money. Some men just want to watch the world burn."
