From someone with experienceavenging . . .only do things that help you or somebody else. Life is too short for anything else.Make a list of what you can gain and what you can lose by focusing your energy on revenge. Most chances are you have more to lose, like time spent on your next buck, than you have to gain.

Be selfish - the reason the bible warns us against revenge is the harm it does to the revenger (you), not the revengee.

If you really believe you can stop them, get away with it,and you or somebody else benefits . . . go for it. But then it's not revenge, its a solution.

Edit - I see you're a vietvet so you're probably older than me. I didn't mean to lecture, just offering advice that you asked for.
