Bruce Wayne: My parents deserved justice.
Rachel Dawes: You're not talking about justice. You're talking about revenge.
Bruce Wayne: Sometimes they're the same.
Rachel Dawes: No, they're never the same, Bruce. Justice is about harmony. Revenge is about you making yourself feel better. Which is why we have an impartial system.
Bruce Wayne: Your system is broken.
Rachel Dawes: [Rachel makes a sharp turn] You care about justice? Look beyond your own pain, Bruce. This city is rotting. People talk about the depression as if its history, and it's not. Things are worse than ever down here. Falcone floods our streets with crime and drugs, preying on the desperate, creating new Joe Chills every day. Falcone not have killed your parents Bruce, but he's destroying everything they stood for.
[She parks in front of a building]
Rachel Dawes: You wanna thank him for that, here you go. We all know where to find him, but as long as he keeps the bad people rich and the good people scared no one will touch him. Good people like your parents who will stand against injustice, they're gone. What chance does Gotham have when the good people do nothing?
Bruce Wayne: I'm not one of your good people, Rachel.
Rachel Dawes: What do you mean?
Bruce Wayne: All these years I wanted to kill him.
[reveals his gun]
Bruce Wayne: Now I can't.
Rachel Dawes: [Rachel slaps him twice] Your father would be ashamed of you.
