The description of the Aluring Skull hints at why the hollow are attracted to some people. It says, "''A skull with meekly lingering souls. Throw to shatter and spread souls to attract certain types of enemies." And, "Souls are a concentration of life, and the life-starved Hollows are lured by its power." ''This would explain why hollows don't attack each other. The player (or Chosen Undead) is never fully hollow, close to it, but he never fully loses his humanity/life. As for NPCs attacking the player, I believe that they are indeed hollow because Rhea of Thorolund explicitly states that Vince and Nico have become hollow, right before they attack you.
