1. Vincent, first of all, is ambitious and courageous. He is still a bit of the demeanor of the previous two godfathers.
2. Insufficient ability, impatient personality, not foresight, like his dad. After the shooting incident on the roof, he wanted to kill the direct leader, and Mike knew that there was a bigger leader behind him, so he stopped Vincent. But Vincent took advantage of Mike's stroke to kill.
3. He neither has the sense of family responsibility like Mike, nor does he have any affection for Mike, and he has no loyalty. He was just very ambitious and wanted to be the successor of the family, so he tried his best to perform in front of Mike. And he is indeed the only candidate: Mike's own son Wuxin has a family business and went to work as a singer; his daughter is innocent and innocent, but also a female. Mike's own children can't do it, so he can only find his brother's children. Because the family cannot fall into the hands of outsiders. Vincent knew this too, so he was confident.
In the end the killer shot successfully and almost killed Mike. I think it has something to do with Vincent.
1. Everyone knows how awesome the killers are. It is obviously not enough to send two people to defend key locations. 2. After learning that the twins had died, Vincent didn't take effective measures to ensure safety, and his expression was strange, as if he was confident. 3. The killer has been subdued and has to shoot out. 4. Mike is dead, Vincent is the eldest of the Corleone family, and he can still be with his cousin. The murder motive was established. Moreover, he killed Mike through the enemy's hands, so he wouldn't be backed up. In the final scene, one person and one dog died, suspecting that Mike had a bleak night scene and was abandoned by Vincent. Or Vincent did not manage well and the family collapsed.
