What does hagen mean by "Families keep their honor" when informing Pentangeli of his task ahead (At the FBI Barracks) ? Does he mean that Pentangelis brother will not get whacked (or injured) by the corleones if Pentangeli kills himself? Or does he mean that Pentangelis brother will be taken care of (in the traditional sense - e.g. financially) if Pentangeli kills himself? Whatever is meant, Pentangeli seems very relieved with this solution.
