(September 2017) (Learn how and when to remove this template message) </Td> </Tr> <P> Revenge is a form of justice usually assumed to be enacted in the absence of the norms of formal law and jurisprudence . (Killers may want revenge, from being bullied .) 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 . Revenge is also known as retribution or vengeance; it may be characterized as a form of justice (not to be confused with retributive justice), an altruistic action which enforces societal or moral justice aside from the legal system . Francis Bacon described it 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 . </P>
