Don Vito Corleone: [speaking to Tattaglia] You are talking about vengeance. Will vengeance bring your son back to you? Or my boy to me? I forgo the vengeance of my son. But I have selfish reasons! My youngest son was forced to leave this country... because of this Sollozzo business! Now I have to make arrangements to bring him home safely. But, if some unfortunate accident might befall him. Or if he gets shot in the head by a police officer... Or if he gets struck by a bolt of lightning, I'm going to blame some of the people in this room! And that I do not forgive. But, that aside, I assure that I will not be the one to break the peace we have made here today.
