Adventures With Chester has a ton of background on the now famous LtGen Jim Mattis who shocked the delicate sensibilities of the fragile flowers in the MSM by stating that he enjoys killing people who beat up women for not wearing a veil (and presumably people who behead innocent captives and people who trick Down's Syndrome youngsters into conducting suicide missions to blow apart other children, etc).
We wouldn't put it quite the way LtGen Mattis did, and in fact we are prudish enough to think that killing should not be "fun" under any conditions. It should be undertaken only with deep regret that it's necessary. Having said that, however, we do not deny that there is something deeply satisfying about justice, and though it should not be regarded as fun, there is, no doubt, a large measure of satisfaction to be taken from knowing that one has removed from the planet someone who preys on innocent women and children and who kills wantonly. Taking the lives of such individuals is an act of justice, it is the right thing to do, and there is nothing reprehensible in LtGen Mattis finding satisfaction in the doing of it.
