Yes. Ironically, had Michael simply been a gangster he might've had a much happier life. When you think about it, it was his quest for legitimacy that caused most of his problems. He was brought into dealings with Roth due to a desire to eventually be legitimate. He didn't whack Roth after Lake Tahoe because of his intense desire for Roth's casinos, to be legitimate--Causing him immense personal and professional grief.

He would've been a great Mafia boss, after consolidating the Corleone Family's power with the Massacre of '55. Or, had he never entered the Mafia, he probably could've been an excellent politician or a great corporate executive. Michael wanted to use one to be the other, or to be both at once--To live in both worlds. And you can't.

If we take III into the equation, ALL of the problems that happen to him in that film stem from his refusal to let his fellow Mafia bosses share in Immobiliare, in order to be legitimate. Had he cut them in and worked as a gangster, no assassination attempt, no war, no dead daughter.

Vito said often (in the novel), "A man has but one destiny." Perhaps Michael's tragedies came as a result of trying to ALTER his own pre-set destiny. Perhaps his destiny was to be a man like his father: A Mafia chieftin. In trying to change his destiny, he caused himself and his family only grief.

Sort of like trying to defy the Metaphorical Fates.
