Avenge vs. Revenge: What's the Difference?
Revenge
Revenge is a form of justice usually assumed to be enacted in the absence of the norms of formal law and jurisprudence. Often, revenge is defined as being a harmful action against a person or group in response to a grievance, be it real or perceived. It is used to punish a wrong by going outside the law. This is because the individual taking revenge feels as though the law will not do justice.
