“Jason Todd: Bruce, I forgive you for not saving me. But why? Why on God's Earth is HE still alive? Ignoring what he's done in the past. Blindly, stupidly, disregarding the entire graveyards he's filled, the thousands who have suffered, the friends he's crippled. You know, I thought... I thought I'd be the last person you'd ever let him hurt. If it had been you he beat to a bloody pulp, if he had taken you from this world, I would've done nothing but search the planet for this pathetic pile of evil death-worshiping garbage and sent him off to Hell.
Bruce: You don't understand. I don't think you've ever understood.
Jason: What? What, your moral code just won't allow for that? It's too hard to cross that line?
Bruce: No! God almighty, no. It'd be too damned easy. All I've ever wanted to do is kill him. But if I do that... if I allow myself to go down into that place... I'll never come back.
Jason: Why? I'm not talking about killing Penguin, or Scarecrow, or Dent. I'm talking about him. Just him. And doing it because... because he took me away from you.”
