The proverb “revenge is a dish best served cold” suggests that revenge is most satisfying when it is carefully planned and executed over a long period of time. The implication is that taking revenge immediately may provide temporary satisfaction, but it is ultimately more satisfying to wait until the perfect moment to strike.
There are several reasons why revenge may be seen as more satisfying when served cold. First, it allows the person seeking revenge to carefully consider their actions and ensure that they will have the desired effect. Second, it can be more difficult for the target of revenge to anticipate and defend against an attack that has been planned over a long period of time. Third, serving revenge cold can allow the person seeking revenge to savor the moment and enjoy the feeling of superiority that comes from getting the last word.
