In much of the Abrahamic scripture there is the idea of retribution in the famous (or infamous) form of "eye for an eye, nail for a nail, tooth for a tooth." So I wonder whether true vigilantism (By true I mean retribution in the form of civilian justice without emotional involvement in the matter) is ethical. A great example of vigilantism would be the part in Star Wars Episode 2 The Clone Wars in which Anakin Skywalker avenges his mother who was tortured, suffered, and eventually succumbed to death in the arms of Skywalker. Then afterwards, upon being enraged by the recent death of his mother, killed not only those culpable, but the women and children. Although Anakin's actions was thus fueled by the love of his mother, would his actions be ethical? If someone commits a massacre under the guise that their action are to prevent future suffering could we say that through this moral ambiguity their actions were somewhat good?
