When Tom tells Vito that Luka wants to see him, Vito asks if it's necessary, kind of giving the impression that he doesn't really like him.
Ignoring Vito calling Brasi his oldest and dearest friend, which could be just for show, after Vito is shot, there's mention that even if they could stop Sonny from trying to get revenge, there'd be no stopping Brasi, implying that Brasi has high loyalty to Vito and truly cares about him. But Vito also sent Brasi to spy on Tattaglia telling him to give the impression that he was unhappy with the Corleone family, which no one would believe if everyone thought he was so loyal, although Tattaglia clearly didn't believe it.
So, did Vito actually like Luka?
