Yes Im referring to the events in the Illumination module and Purge the Unclean in which the acolytes risk receiving corrpution points for harming innocents while doing their duty to the inquisition. As i see it Corruption stems from the warp and maybe lust for personal power/wealth, not dedication to the god emperor (otherwise Exterminatus would be the ultimate corrption, everyone ivolved going max corrupted right away).
But is there another way to handle disregard for human life? Insanity points? Fear test level +10? Not every acolyte is a stone cold killer and there should be something to make it less appealing to just blaze away into a crowd, at least for those not already jaded.
