The henchman should be honored, because without the honor, there would be no reason for the henchman to kill - the personal risk is too great, and the personal reward too little. But the mob as a whole clearly benefits from killing rivals, so by introducing honor (which, for someone without it, is worth a lot), everyone can expect a positive payout (except for the rival). I think you'd probably object to my ignoring the totality of the situation - a murder has been committed. But what's the harm in murder as long as it's happening external to "our civilization"?
