...Agh. Are you deliberately dodging?
Again: Tarquin is Malack's friend, peer, equal and party leader. Xykon is Redcloak's slavemaster and sadistic torturer. There is no comparison here. Malack describing Tarquin as a "fool" does imply that Tarquin does nothing Malack finds sufficiently vile to be more important than the way his silly behavior annoys Malack; why on earth is that showing up in a defense of Malack's moral sense, rather than in an argument that Malack is comparably evil to Tarquin himself?
