When I take revenge, I often don’t do it purely to see the other person miserable. It may be interesting to see how I hurt someone, but often I have an ulterior motive.
An example, this girl spent two years constantly attempting to walk over me and would talk about me behind my back and was generally a disturbance to my work life by trying to get other people to dislike me and ‘gang up’ on me. So, I found out who her boyfriend was and I managed to break them up. I did this without anyone ever knowing I had anything to do with it. This meant that her attention was then focused on crying over her loss, everyone else’s attention was on her, and I had a clear path to get on with what I wanted. Seeing her misery was also rather enjoyable.
All revenge must be suitable for the situation. The best way to carry out revenge is to do so subtly without being caught but still being the reason for their misery. Never be tempted to take the spotlight for your genius revenge plot, because it will only end badly for you and it isn’t worth the five minutes of fame.
Revenge doesn’t have to be in your face. No one needs to know it’s you. I find the best tactic is to skulk in the dark and slowly implement changes to destroy them in any way I need. For example, in Dexter season 7, his babysitter’s boyfriend Lewis was causing him problems. So after warning him, he found a way to get Lewis fired from his job and dumped his his girlfriend so then the guy was out of his life. No one ever knew it was Dexter.
All revenge needs to be is payment for their actions. If you follow this, don’t leave a trace. Threats must be face to face and then there is no proof of this ever having happened.
But really this depends on whether you want someone to know that they are getting what they deserve for hurting you, kind of a warning to leave you alone, or if you just want to get them out of the way and see them suffer from behind a mask.
