If Michael didn't continue his strength, someone else would be gunning for his empire,someone like Roth.

If I was in Michael's situation, I don't know if I would handle it any different than he had. Michael built his empire into the billions, making Vito's fortune look small during his time. Michael created a skill to balance both his worlds of legitimate & illegitimate enterprises under one umbrella while still managing to fly underneath the radar and triumphing over the senate and authorities.

I don't believe Michael was ever a villain, he believed in family and loyalty, never mistreated Kay or cheated her & gave everything to his family. A hero for-sure.
