Was Barzini's beef personal? I think Barzini's moves against Vito were "personal" in the sense that he thought of himself as No.1 waiting in the wings, impatient to be the top dog in NYC, younger than the other Dons, whom he regarded as "Moustache Petes" (per the novel). But, I don't think he had a personal grudge against Vito
And ultimately that's why Barzini wasn't as great as Vito. Vito took EVERYTHING personally despite his outward statements that he didn't (take everything personal).
