What I refer to as Southern Justice is handing out justice to those who have harmed you in such a manner that no one ever tries it again.
When the great (at what he did) Reinhard Heydrich was murdered by the British-directed plan in Czechoslovakia in 1942, Hitler's response was so brutal that Britain backed off on similar attempts.

Sippenhaft is a German term for the idea that a family or clan shares the responsibility for a crime or act committed by one of its members, justifying collective punishment.
In Unforgiven, we see this response by Will Munny:
It is time we hit back at the rioters in a similar (Sippenhaft) fashion.
