I've thought about this scene quite abit, I'll have to admit I agree with Michael's decision about executing Fredo. Fredo "has a good heart"...but honestly through out the movies he hasn't shown any loyalty or appreciation to Michael as a brother at all. Yes I understand he was "stepped over" but he had no right going behind Michaels back and associating with Michaels enimies for his own benefits. To me, that is a big sign of a traitor. In family a traitor should never be forgiven. I feel no sympathy for Fredo at all.
