Don Corleone: Why did you go to the police? Why didn’t you come to me first?
Bonasera: What do you want of me? Tell me anything, but do what I beg you to do.
Don Corleone: What is that? [Bonasera whispers his request in the Don’s ear] That I cannot do.
Bonasera: I will give you anything you ask.
Don Corleone: We’ve known each other many years, but this is the first time you ever came to me for counsel or for help. I can’t remember the last time that you invited me to your house for a cup of coffee, even though my wife is godmother to your only child. But let’s be frank here. You never wanted my friendship. And, uh, you were afraid to be in my debt.
Bonasera: I didn’t want to get into trouble.
Don Corleone: I understand. You found paradise in America, you had a good trade, you made a good living. The police protected you and there were courts of law. And you didn’t need a friend like me. But, uh, now you come to me, and you say: “Don Corleone, give me justice.” But you don’t ask with respect. You don’t offer friendship. You don’t even think to call me Godfather. Instead, you come into my house on the day my daughter is to be married, and you ask me to do murder for money.
Bonasera: I ask for justice.
Don Corleone: That is not justice. Your daughter is still alive.
Bonasera: Let them suffer then, as she suffers. How much shall I pay you?
Don Corleone: Bonasera, Bonasera. What have I ever done to make you treat me so disrespectfully? If you’d come to me in friendship, then this scum that wounded your daughter would be suffering this very day. And if by chance an honest man like yourself should make enemies, then they would become my enemies. And then they would fear you.
Bonasera: Be my friend – Godfather. [The Don shrugs. Bonasera bows toward the Don and kisses the Don’s hand]
Don Corleone: Good. Someday, and that day may never come, I’ll call upon you to do a service for me. But until that day – accept this justice as a gift on my daughter’s wedding day.
Bonasera: Grazie, Godfather.
Don Corleone: Prego. Give this to, uh, Clemenza. I want reliable people, people who aren’t going to be carried away. After all, we’re not murderers, in spite of what this undertaker thinks.
