I agree. Michael was addicted to power. His whole life after he returned from Sicily was geared toward holding the power that comes with being a Don, and trying (desperately) to be "legitimate" at the same time.
Ntra la porta tua lu sangu � sparsu, E nun me mporta si ce muoru accisu... E s'iddu muoru e vaju mparadisu Si nun ce truovo a ttia, mancu ce trasu.
