I think it's just human nature to not hire people you feel you won't get along with. If you're deeply involved in all your hires, then I feel you'll end up with an organization full of people that you get along with and who you like (and probably like you back). I wouldn't go so far as to say it'd make a personality cult - though with their lofty mission statements and ambitions to make the world better.. who knows. Not going to psychoanalyze a bunch of people I don't know

"I've hired people I "don't like" on a personal level."

I'm honestly impressed... I feel that's rather exceptional. I feel a lot of hiring goes on "gut feeling"
