It's all rather complicated when you start speculating about motivations. However, I am surprised that someone who had Michael's intelligence and intuition did not pick up on Fredo's feelings.
That's a very good point, Oli. Had Michael been less selfish and self-centered, he might have either tried to keep Fredo satisfied, or at least perceived that he was creating an enemy.
