Vito went back years later and killed, a senile, one leg in the grave, Don Ciccio who was living out his last days thousands of miles away absolutely no threat to the Corleones as revenge for killing his family because same as Michael the enemies have to be wiped out
I think it's important that Vito do this. Part of Michael's tragedy is that when learns his lessons, he becomes trapped by them. If he learns to pursue enemies to the grave, then he'll do so without discretion.
Nice take, though!
