Two-Face
You thought we could be decent men in an indecent time. But you were wrong. The world is cruel, and the only morality in a cruel world is chance. Unbiased. Unprejudiced. Fair.

Do you want to know why I use a knife? Guns are too quick. You can't savor all the... little emotions. In... you see, in their last moments, people show you who they really are. So in a way, I know your friends better than you ever did. Would you like to know which of them were cowards?
Joker
So I had a wife. She was beautiful, like you. Who tells me I worry too much. Who tells me I ought to smile more. Who gambles and gets in deep with the sharks. One day, they carve her face. And we have no money for surgeries. She can't take it. I just want to see her smile again. I just want her to know that I don't care about the scars.
Joker
Oh, you. You just couldn't let me go, could you? This is what happens when an unstoppable force meets an immovable object. You truly are incorruptible, aren't you? You won't kill me out of some misplaced sense of self-righteousness. And I won't kill you because you're just too much fun. I think you and I are destined to do this forever.

Some men aren't looking for anything logical, like money. They can't be bought, bullied, reasoned, or negotiated with. Some men just want to watch the world burn.

A long time ago, I was in Burma. My friends and I were working for the local government. They were trying to buy the loyalty of tribal leaders by bribing them with precious stones. But their caravans were being raided in a forest north of Rangoon by a bandit. So, we went looking for the stones. But in six months, we never met anybody who traded with him. One day, I saw a child playing with a ruby the size of a tangerine. The bandit had been throwing them away.
