We are all products of our upbringing. However much we think we are not like our parents, more often than not, we turn out alot like them. Michael is Scilian and raised by a man who said: Where I come from, if you go to kill a man, you better finish him off.

Even though Michael may have wanted to get away from the family business more than anything, he wasn't going to get away from his upbringing. If Michael had succeeded in going legit as he'd always wanted, that belief system would still be in place. The second anyone tried to pull anything on him or his family, I am pretty sure he's still react as the Scilian he is.
