Vengeance. A rather ominous sounding word on its own, when put to use, it can be very powerful, harmful, or even embarrassing depending on who you are and where you come from. This concept has been in use for thousands of years. probably since before man could create fire and hunt with spears.
But, vengeance can be a driving force in a story. The slighted victim who wants to make their bully feel the same kind of shame and hurt they felt. Or, as in ancient Japan, vengeance is used to regain honor in the eyes of your family and more specifically your ancestors.
It can be better thought of as the ‘eye for an eye, tooth for a tooth’ way of thinking. It can be a plot point which helps to push the protagonist forward and make them do things they wouldn’t normally consider. Or, it could be the entire plot of the story where the main character goes through all kinds of hoops in order to exact their revenge on the person who insulted, stole/murdered family member/friend.
But, the one thing to keep in mind when it comes to vengeance. It is a dish best served cold.
