My take as well Evita “he [Vito] wouldn't retire from a weak and defeated position as
former Top Don”
Note: Lou's was an assumption
Extract: assuming that Don Corleone is wanting to retire,and hand over the reins of the Family
I believe, it would have been of utmost importance - Vito's [Corleones] need, pride to re-establish the Corleones glory, standing, reputation etc. and to make the Corleones top Mafia family again
Fredo in charge, even as a token "front Boss" under the watchful eye of Tom and Vito
It could work....Fredo knows to keep his mouth shut! unlike Sonny
there's not gonna be no trouble from Fredo as long as Vito is alive Then send Fredo fishing with Neri!
Extract: Fredo- Capo,but limited to rackets and soldiers given to him by Vito
Ironically I believe, Fredo would have had no problem as “Capo,but limited to rackets and soldiers" or taking care of some Mickey Mouse night club somewhere!
It was the stepped over for his
kid brother that got Fredo mad and all fired up....
