“Vito was “straightlaced about sex†and “would consider such cavorting by his son Freddie, two girls at a time, as degeneracy." Vito also knew Sonny had goumars
Vito was “displeased†but did nothing, yet Vito is the family man! Go Figure!!
I think it is fleshed out in the book that he was dismissive of Fredo something like why? Mama can do the cooking when Tom asked should they bring the only son home after Sonny's death and Michael in hiding
