In general, you guys are more like avengers, watch fewer Hollywood movies! :) Only there do they seek revenge for the death of loved ones, taking revenge for a long time and cruelly, planning their revenge for years, etc. In the real world, this does not exist and cannot exist – and the exceptions in the form of paranoid maniacs with a fixed idea of revenge only confirm the rule.
In reality, everything is much smaller and simpler – let's say you're playing online :) (after all, the forum is dedicated to computer games). The situation is this: there's you and, for example, three other players, each playing for themselves. Red periodically comes and captures your mines while you're leveling up your hero; finally, your main hero returns, gathers an army, and goes... where? There are two paths: you can attack Red, or you can attack Green, who hasn't shown any activity yet; the road to both is the same length, you don't know anything about the size of their armies, and they have the same race. So, who will you attack?
Revenge is something like the opposite of gratitude. In principle, it's a bad feeling; I think it's better to try to overcome it.
And finally: the judicial function of the state, in fact, consists precisely in taking revenge on criminals...
