Don Corleone: "But I'm a superstitious man. And if some unlucky accident should befall him...if he should get shot in the head by a police officer, or if he should hang himself in his jail cell, or if he's struck by a bolt of lightning, then I'm going to blame some of the people in this room. And that I do not forgive. But that aside, let me say that I swear, on the souls of my grandchildren, that I will not be the one who will break the peace we have made here today."
