what's that then?
at least if you're doing it because you want to inspire fear in a population you kinda have a reason or for information.
doing it just because they hurt you though serves no purpose whatsoever and won't change a thing
That's entirely subjective though - people deal with things in different ways. If inflicting pain on somebody gives them the 'closure' that they need after the person has hurt them or somebody they love, then that's what is right for them. There is no right or wrong way to deal with it?
