But if Sonny, as the older brother and "head" of the family, was taking care of Fredo, would he have resented it as much?? Or at all?? If his resentment of Michael stemmed from the fact that he, Fredo, was passed over, if Sonny had lived, would he have ever gotten jealous? And therefore would he ever have betrayed the family? Or was his resentment (look at the way that Sonny spoke to him on Pearl Harbor Day) inevitable?
