I believe that what doesn't kill you, simply makes you... stranger.
You wanna know how I got these scars? My father was a drinker and a fiend. And one night, he goes off crazier than usual. Mommy gets the kitchen knife to defend herself. He doesn't like that. Not...one...bit. So, me watching, he takes the knife to her, laughing while he does it. He turns to me and he says, "Why so serious? He comes at me with the knife. "Why so serious? Sticks the blade in my mouth...Let's put a smile on that face!
you'll see, I'll show you, that when the chips are down, these uh... civilized people, they'll eat each other. You see, I'm not a monster. I'm just ahead of the curve.
Do I really look like a guy with a plan? You know what I am? I'm a dog chasing cars. I wouldn't know what to do with one if I caught it. You know, I just do things. The mob has plans, the cops have plans, Gordon's got plans. You know, they're schemers. Schemers trying to control their worlds. I'm not a schemer. I try to show the schemers how pathetic their attempts to control things really are. So, when I say that you and your girlfriend was nothing personal, you know that I'm telling the truth.
It's the schemers that put you where you are. You were a schemer, you had plans, and uh, look where that got you. I just did what I do best. I took your little plan and I turned it on itself. Look what I did to this city with a few drums of gas and a couple of bullets. You know what I noticed? Nobody panics when things go according to plan. Even if the plan is horrifying. If tomorrow I tell the press that like a gang banger will get shot, or a truckload of soldiers will be blown up, nobody panics, because it's all, part of the plan. But when I say that one little old mayor will die, well then everyone loses their minds!
[Joker hands Two-Face a gun and points it at himself] Introduce a little anarchy. Upset the established order, and everything becomes chaos. I'm an agent of chaos. Oh, and you know the thing about chaos? It's fair.
