Eh, I don't think that's really how it is for Hisoka actually.
He uses Ren to root out the fodder from the strong. Surviving his Ren is a prerequisite for even getting the chance to fight him. The reason we don't see more characters, like say Phantom Troupe members, succumbing to its effects is that this stuff simply doesn't work on most high level Nen users (unless they have insane potency like the Royal Guards, Meruem, or Netero). That's the reason it doesn't come up often, not because it's something out of character for him. If anything, Hisoka is one of the most likely characters in the series to project bloodlust IMO, especially when he's excited or agitated.
