If I remember correctly Fredo was not killed in the book, and Puzo didn't want Michael to kill Fredo in the movie because he thought the audience would hate Michael to much afterwards but FFC wanted it to happen and kept on about it so Puzo told him to wait until Mama dies so at least their mother would be dead and wouldn't have to live with another dead son, and Puzo thought the audience wouldn't hate Michael if he waited until his mother passed, and I think it worked
Like think about it.....Michael Killed his OWN Brother and I still have respect for the guy
