I noticed this about myself... I dont always follow through, but when someone hurts me I have an insatiable desire to hurt them back equally or say something back to crush them equally.
I wonder how many types do this, I would assume this is a mostly NF thing. The NTs I have dealt with can be nasty too but they don't ever seem to get hurt and want to hurt back the same way I have seen NF's.
I wonder where this stems from aside form immaturity I mean, some people need to bite back.
