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.
