Lana, I admire your faith in Michael's brotherly concern for Fredo. But I don't share it. I don't think Michael loved anyone or anything except power. He just wanted to get everything from Fredo that he knew about Roth; once he got that in the boathouse meeting, Fredo was "nothing to me now." I think he did love Kay before Vito's shooting put him into the Family business. But when he returned to the US, I think she was basically a WASP ticket-punch for Michael--another ornament in his quest for "respectability." That scene in New Hampshire with him "wooing" Kay (Michael wearing that ridiculous Homburg hat, looking like a pint-sized banker) had all the passion of a real estate negotiation--with Kay as his property.
