My two cents worth!
Vito and Michael sentiments aside....

Vito is seen through rose-coloured glasses
Finally the truth! No doubt he was a cold blooded murderer despite his outward nice guy appearances! committing horrendous acts, cold blooded gruesome murders, destroying families

Lana, by the way, great comparison of Vito and Michael were not dissimilar in their - before and after – becoming evil, ruthless, murderous crime boss Like father like son

Keep harping on! No doubt Carmela is the one who kept the family together
Michael's wife [“and Kay -- well -- Kay was -- well --”] became Michael's horror
