Just to let you in on something before I give you what you deserve: "an eye for an eye" has long been the standing policy for many humans, going all the way back to Hammurabi. Perhaps it's related to reciprocal altruism
— just as people are prone to repay kindness with kindness, they are also prone to Pay Evil unto Evil. In any case, the concept of revenge works even better in fiction, but in other works, an Aesop on the futility of revenge is frequently featured (naive optimists).
For many avengers like me, revenge is an obsession. Compare Crime and Punishment Tropes, Hatred Tropes, & Morality Tropes. Contrast A Forgiving Index (like hell I'll forgive you!).
These tropes are gonna pay for what they've done!:
