Question: What was the purpose of the flashback at the end?

Answer: It was done as a way of showing Michael reflect on the past. To show the kind of person Michael was before the events of the two movies and how much he has changed since then. We also get to see the Corleone family at a much happier place before things started getting complicated. By this point in the story, Fredo has been killed and his wife has left him, and this flashback scene serves as a reminder of how much he has lost despite having everything.

Casual Person

Other mistake: When Paolo is shot dead, there's blood dripping down the rocks he's lying on, but there shouldn't be. The rocks are under his shoulder, and he was shot in the back, and a little blood dripped out sideways. And there's no blood on his shirt where his body is touching the rocks.
