REVENGE.

Synonyms:

avenging,retaliation,retribution,vengeance.
requital,

Revenge is the act of making return for an injury done to oneself by doing injury to another person. Retaliation and revenge are personal and often bitter. Retaliation may be partial; revenge is meant to be complete, and may be excessive. Vengeance, which once meant an indignant vindication of justice, now signifies the most furious and unsparing revenge. Revenge emphasizes more the personal injury in return for which it is inflicted, vengeance the ill desert of those upon whom it is inflicted. A requital is strictly an even return, such as to quit one of obligation for what has been received, and even if poor or unworthy is given as complete and adequate. Avenging and retribution give a solemn sense of exact justice, avenging being more personal in its infliction, whether by God or man, and retribution the impersonal visitation[317] of the doom of righteous law. Compare [AVENGE]; [HATRED]; [REQUITE].
