My actual point tbh was that it was not the Kill Teams mission, perogative or responsiblity to Punish/Kill/Question the Governor. They are to locate the inquisitor, and follow instructions from there.
Kill Teams who blow away the governor (yes he probably deserves it) should be cautioned (certainly if they actually escape the planet) for over stepping the Mark and mission parameters.
If of course they believe the Governor has been infected, then it's fair game as he is now considered Xenos.
