Or what if Anthony becomes a legitimate politician and has a completely legitimate life. Vincent is a horrible don, dealing with drugs and getting the Corleone family in major trouble with other families because of his temper. Michael doesn't like what is happening, but since Vincent is don, he doesn't do anything. A rival family has a big problem with the Corleone family, and instead of going after Vincent, they go after Anthony and his family to get to not only Vincent, but Michael. Anthony knows what is going on, and goes to Michael for an explanation. The family kidnaps all of Anthony's family and the Corleone's try to figure out who exactly is doing all of this. Vincent finds out from sources who it is, and before he says anything to Michael or Anthony, he goes after the people and dies doing so. All of these events completely change Anthony, like how Michael changed, and eventually becomes don to try to completely legitimize the family so that there is no more violence.
