Apple, I agree that Michael killed his brother because he betrayed the family, IMO Fredo deserved to be killed. I did not say Michael did those things because he was frigid, I said Mike may have been a little frigid to begin with. You can see this in the flashback scene at the end of part II, that was before his relationship with Kay.
I was just stating that Michael grew more cold-hearted the longer he was Don. I didn't say he did anything because he was frigid. He had reasons, but they were COLD calculated ones. I mean, come on, you have to have grown a little cold-hearted to kill your own brother, betrayed or not.
