Michael Corleone: Just when I thought I was out... they pull me back in.
Michael Corleone: I, uh, betrayed my wife. I betrayed myself. I've killed men, and I ordered men to be killed. No, it's useless. I killed... I ordered the death of my brother; he injured me. I killed my mother's son. I killed my father's son.
Michael Corleone: [after learning of Zasa's assassination] Don't ever give an order like that again. Not while I'm alive.
Vincent Mancini: Uncle Mike, it had to be done. You were too sick to make a decision. I got the go ahead from Neri and Connie.
Michael Corleone: Connie.
Vincent Mancini: It was the right
thing to do.
Michael Corleone: It was not the right thing to do. I command this family, right or wrong. It was not what I wanted! Understand?
Vincent Mancini: Yes.
[Michael looks at Neri]
Al Neri: Yes.
[Michael looks at Connie for a long time]
Connie: Yes!
Michael
Corleone: Vincent, help me to my bed. I want to talk to you alone.
Michael Corleone: [Vincent helps Michael into his bed] My brother, your father, he and I. Opposites. But I never doubted his love. He would do anything for me. But his temper. Clouded his judgement. I don't want to see the same thing happen to you.
Vincent Mancini: [in the helicopter] I'd like to take Joey Zasa up in one of these and drop him.
Michael Corleone: Joey Zasa is nothing. He's a small-time enforcer. He bluffs, threats, but nothing. You can see him coming a mile away.
Vincent Mancini: We should kill him before he kills...
Michael Corleone: No!
Never hate your enemies. It affects your judgment.
Vincent Mancini: You had a gun. They only had a knife. You could have talked them into surrendering. Turned them over to the police.
Vincent Mancini: Hey, Uncle Mike, Zasa sent these guys I was just sending him a message that's all.
Michael Corleone: Now he has to send you a message back.
Vincent Mancini: Joey
Zasa's gonna send me a message? Joey Zasa's gonna send me a message?
Connie: Michael, he did the right thing. He got Zasa's name.
Michael Corleone: What's Joey Zasa got to do this this? Joey Zasa's a patso. Joey Zasa. Alright, you are what you are. It's in your nature. From now on you stick close to me. You don't go anywhere, you don't do anything,
you don't talk to anyone without checking with me first, understand?
Vincent Mancini: Yeah.
Michael Corleone: I've got problems with the commission, young man!
Vincent Mancini: Yeah, I know.
Michael Corleone: You don't make them any easier.
Vincent Mancini: I know.
Michael Corleone: Alright, go on. Get out of here.
Connie: Michael.
Michael Corleone: Yes.
Connie: Now they'll fear you.
Michael Corleone: Maybe they should fear you.
