Clemenza: [fish tank scene] “Don Corleone you once said that the day would come when Tessio and me could form our own Familyâ€
It seems to me the above was the carrot Vito has been dangling and both Clemenza and Tessio seemingly were receptive of the said arrangement / reward
Clemenza and Tessio already had their own territories They could have continued to run their respective Families [like a Corleone!] without Michael on their backs
Michael can still draw the water from their well for muscle and they can certainly present a bill for such services
After all Michael is not a Communist!
It does beg the question why set up the betrayal, knowing there could be one or more possible traitors? Why not take them, the long term trusted Corleone people into confidence?
