1. Was Vito correct in his decision to not partner with Sollozzo?
2. Would Sonny have made a better Don than Michael? Why or why not?
3. What would Don Vito have thought of Michael?s choices?
4. What was Michael?s real motivation when he decided to take over the family?
Well, Vito had his principles, so it was good that he stuck with them, but in the real world, drugs were the future, and he probably should gone that route.
Sonny? No. I mean, they killed him right off the bat. Too hot-headed, never would've worked.
Vito of course would've been upset with Michael. Killing Fredo was a bad, bad thing. Even Michael realized that in time. Family was the most important thing to Vito. Realistically, Vito would've made sure that Fredo was doing something important, or at least felt valued. Fredo never would've had to betray the family if Michael had behaved properly and treated Fredo with respect. Vito had respect for all this sons. Michael really screwed up by messing with things in Vegas.
I think Michael was motivated by revenge/vengeance. My assumption is that Michael has a bit of PTSD from the war, and all he knows is killing/violence to solve problems, whereas Vito tries to negotiate. We know he left the family to go to college, then joined the Marines. So I think Michael ran things how he thought the mob was run, just through violence, since that's really all he knows, from what he read and what he experienced in WW2. I'm not sure how much he was exposed to before he left.
During his time in Sicily, he learned more about the violent nature of his family. Of course, his brother was murdered and his father narrowly survived assassination. In the very short time he spent back with his family, all he knew was violence, so that's what he did in kind.
I will say, I don't think we know enough about how Vito ran the family. The flashbacks in Part II show he's a fairly benevolent, reasonable person, but there's 30-40 years that we don't see. I assume he's a fairly benevolent ruler, and not prone to violence, but he may have had many people murdered. He may have been violent in front of Michael, but we just don't know enough.
