10 of the Most Memorable Betrayals in Movies

5. Fredo Corleone - The Godfather: Part II

As the second son of Vito Corleone and elder brother of Don Michael Corleone, Fredo feels understandably sidelined within the family business and is treated as the most weak and unintelligent of the Corleone brothers. It's these feelings of inadequacy that drive Fredo to go against the family by trying to arrange a deal with an agent of rival mobster, Hyman Roth, the details of which are scarcely mentioned in the film.
