How we cite our quotes: All quotations are from The Dark Knight.
Quote #7
BATMAN: I know now what I have to become to defeat men like him.
Batman's defining the terms of defeat here. Is the cost he would pay to stop the Joker so awful that it would nullify the victory itself? That's a grim question which Bruce is going to have to answer before the end of this.
Quote #8
THE JOKER: I took Gotham's white knight and I brought him down to our level. It wasn't hard. You see, madness, as you know, is like gravity. All it takes is a little push!
Here's the tough thing for Batman: he has to beat the Joker every single time. The Joker only has to win once. So sure, Bats shows him up with the whole ferry-passengers-not-embracing-the-void thing. But as he said, he's got an ace in the hole, and none of Batman's victories will matter if he can't stop it.
Quote #9
TWO-FACE: The Joker chose me!
BATMAN: Because you were the best of us. He wanted to prove that even someone as good as you could fall.
TWO-FACE: And he was right.
BATMAN: You're the one pointing the gun, Harvey. So point it at the people responsible.
TWO-FACE: Fair enough. You first.
When you get Gotham's two most stalwart defenders shooting each other in the gut, it's a pretty darn good day for Team Evil.
