He broke that one, too, I'd say. Killing a brother does not honor thy Mother and Father.
I'd semi-agree with you, Capo. The main theme for me is Michael's (and Don C.'s) attempt to protect their world and family, their mis-guided use of force, revenge and vengeance as a tool to protect their family, and by using these tools, the ultimate loss of their family.
