of course... it'll drain the production/etc.. hence the caveat of those alive go home afterwards to boost the pop back.
only question is whether that mob will do any harm to the infidels to make it worth it
regardless of what happens inside that region.. nearby enemy (i.e. looter's realm) regions with significant following should get hit by unrest. only trouble is the 2+ realm vs 1 thing where you'll get some far away realm who pops in to loot so the nearby one doesn't get hurt. (seen that for TO/sympathy stuff i think) need to figure out how to stop that arising, maybe looter's ally get hit with unrest.
