A captain is supposed to love his crew equally but its clear Luffy only has love in his heart for the monster trio and Nami.
In FMI, Luffy only trusted Sanji and Zoro with sending Big Mom a message
In WCI, Luffy handled Sanji way diffrent than hes handled any other crew member leaving the crew, he never told Robin, "I cant become pirate king without you!"
He hardly ever talks to his crewmates, in fact i cant even remember the last time he spoke to Franky
Thats not a sign of a good captain
