revenge

Revenge is a form of justice enacted in the absence or defiance 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. Francis Bacon described revenge as a kind of "wild justice" that "does... offend the law [and] putteth the law out of office." Primitive justice or retributive justice is often differentiated from more formal and refined forms of justice such as distributive justice and divine judgment.
