Fredo told Michael, "He [Johnny Ola] said there'd be something in it for me." He betrayed his brother for personal gain. "I swear to God I didn't know it was gonna be a hit." In other words, Ola didn't tell him it was gonna be a hit, and Fredo didn't ask why Ola wanted him to open the drapes to Michael and Kay's bedrooom. What did Fredo think was going to happen?

Michael's ordering of Fredo's murder was a horrific act. Michael was a reprehensibllle man, heading a reprehensible criminal empire. But, from his viewpoint, Fredo had to die. Fredo's outburst in the boathouse revealed the depth of his resentment toward his brother. Sooner or later, someone elserwould approach Fredo with yet anpther death-dealing offer. And, as Don, Michael had to prove to enemies and even friends that no one--not even his brother--gets a pass from Michael Corleone, no one finds a c***k l in his armor. As Hyman Roth said, "This is the business we've chosen."
