I think you all are wrong about Mike and Tom's relationship. Mike knew no matter what he did or what he told Tom to do that he would always be loyal to te family and nothing else. He lovd Tom for all he had done for his family. Why do you think he got mad before the talks about Roth? Because he thought Tom was slowly working his way out the family wnd was hurt. Mike would never kill Tom and leaned on him during his whole life.
