If Michael had not been greedy, burrowing into Roth's empire ie: satisfied with his Nevada gambling business, Roth and Ola would have had no reason to cultivate Fredo to betray Michael and the Tahoe bedroom shooting would not have happened
It seems to me, on further review! Michael wasn't greedy as such because Michael thought “Roth acts like I'm his son, his successor†and Roth was 'gifting'! Michael Roth's business until the Tahoe shooting
