No doubt Roth was incredibly clever and resourceful in Godfather 2
I reckon, in terms of most irreparable permanent damage and most significant adverse turn of events were caused by
Godfather – Carlo and Fabrizio
Godfather 2 – Fredo and Rocco failing to secure Tahoe
Godfather 3 – Vincent including failing to secure the safety of the Corleones
Why did Michael have Rocco kill Roth if he was a high ranking member of the family? Was it revenge for not keeping the compound secure?
