True, but in the midst of that politiking, the Exec can't necessarily use his rank as an shield/excuse to insult and harass his crew members, particularly crew members capable of squashing his skull like a grape if they get ticked off enough. In particular, reminding a Soul Drinker Marine (repeatedly?) that the Imperium he fights for considers him a traitor isn't conducive to low insurance premiums. If it did come down to a fight, Darvius definitely wouldn't escape unscathed, and could likely die if the Eldar get in on the action, but that wouldn't be a whole lot of consolation to Klaus. :-X
