There's no morality about it. This is EXACTLY why modular security is important. Not only should a city have city walls but people themselves should have walls for their own claims so that a tracked scent indicates exactly who was responsible and when a raiding party shows up to exact vengeance for a crime then the leader can negotiate a village to village truce and either an arrangement for recompense by the accountable or hand over the culprit.
Trying to hash out morality is ridiculous. No one but crybabies and emo empathizers gives a fucking shit.
