I don't understand revenge
Why do people like revenge so much? As if getting back on someone is going to reverse the things he did to you? The only reason you should hurt someone back is to prevent it from happening. That's the whole point of punishment right? Punishing someone so he doesn't do it again. But just raging, being blinded by emotions and just hurting someone back because you're mad at him? That is just irrational.
Now don't get me wrong, I get mad too. A girl I know has an alcoholic father who gets out of control when drunk and I seriously doubt I can keep myself from breaking his bones, making him caugh up blood if he did anything in front of me. But that is a surge of emotions. You have very little control over that, but it is temporary and any rational person will get his sanity back within seconds/minutes/hours depending on the intensity.
What do you think? Is there any reason besides blind rage and selfishness behind revenge?
