Which of these is the protagonist of the novel 'The Godfather'?

Vito Corleone wanted his sons to become successful by legitimate means. He didn't want his family to have to depend on crime in order to survive. He wished for Michael to be a senator or something similar, unfortunately crime was embedded in their DNA.

QueenHamish, Vito is a survivor. Michael is corrupted into a monster.

I truly hope no one chose Tom Sawyer

"Leave the gun, take the cannoli."

I've always seen Michael as the protagonist

Let him sleep with the fish!
