Dinah Madani: You decide someone deserves to be gone, and, bang, they're gone. No second thoughts, no qualms, no conscience. And then on you go, happy and safe on your... I guess at least borderline psychopathic, merry way.

Frank Castle: Listen, Madani, you're right. I can do it. I could kill him and just walk away. But that doesn't mean it's easy. I can live with it, yeah. I can live with anything. There's no peace up here. (points to his head) There's no happy medium that I'm looking for.
