I am not saying Michael was FORCED into the family business. I agree 100% that it was his CHOICE. What I am saying is after he made that choice, his heart became colder and colder...
The point I am trying to make is although Mike was a pretty frigid person to begin with, and he DID CHOOSE to be in the family business, it took time for his heart to grow cold enough that he would order the death of his own brother.
