That whole scene is the epitome of Michael's manipulation of all those around him.
Yes. He practically reduced Tom to tears, telling him, "You're my brother, Tom."
He was even more manipulative when he met with Pentangeli--scaring the s..t out of him by yelling, 'In my house...in my bedroom..." then telling him to put his head in the lion's mouth by "settling these problems with the Rosato brothers." Michael couldn't miss: If they settled, one more worry off of his mind. If they killed Pentangeli, more proof of Roth's duplicity. Michael never more reprehensible than in those two scenes.
