Nothing wrong with self defence, but there's a difference between fighting against/potentially killing an intruder who was going to hurt you/did hurt you and hunting them down once they'd stolen the goods and blasting their head in with a shotgun. Hacking back feels less like the former and more like the latter (ala vigilante lynch mob going after someone who'd done wrong in the past).
