Revenge (also known as vengeance) is a harmful action against a person or group in response to a grievance, be it real or perceived. Although many aspects of revenge resemble justice, revenge is usually depicted as more injurious and punitive as opposed to being harmonious and restorative. Whereas justice implies actions undertaken and supported by a legitimate judicial system grounded upon a foundation of ethics and morals of the majority, revenge implies actions undertaken by an individual or narrowly defined group outside the boundaries of judicial or ethical conduct whose goal is to force a wrongdoer to suffer the same or greater pain than that which was originally inflicted to a party.
