Being a softy for Fredo,the scene that really gets to me is the scene of him sitting on the dock talking to Anthony,knowing how he has dishonored his family(and maybe knowing that his days were numbered)And Tom Hagen on his way to the boathouse to meet Michael stops and gives a warm smile at the two of them.As much evil that Tom has done, at that moment I felt he still had a humanity and an ability of forgiveness in him to appreciate an Uncle teaching his Nephew about fishing.
