I just happened across this while surfing the web. I had to put it up because, quite frankly, it was my favorite part of the movie.
*Spoiler warning* (sort of)
Batman: You either die a hero, or you live long enough to see yourself become the villain. I get to lose things. Because I'm not a hero. Not like Dent. I killed those people. That's what I can be.
Gordon: No, no, you can't! You're not --
Batman: I'm whatever Gotham needs me to be. Call it in.
Gordon: They'll hunt you.
Batman: You'll hunt me. You'll condemn me. Send the dogs on me. Because that's what needs to happen. Because sometimes, the truth isn't good enough. Sometimes people deserve more. Sometimes people deserve to have their faith rewarded.
*Batman runs away*
Gordon's Kid: Batman! Batman! Why is he running, dad?
Gordon: Because we have to chase him.
Gordon's Kid: He didn't do anything wrong.
Gordon: Because he's the hero Gotham deserves, but not the one it needs right now. So we'll hunt him. Because he can take it. Because he's not a hero. He's a silent guardian.
A watchful protector.
A dark knight.
Thank you, that is all.
