While this may sound like justice in theory, in practice it often turns in to a vicious cycle that doesn't end after the initial retaliation. It's especially impractical when most revenge does not exactly equal the first offense. In personal relationships, "an eye for an eye" just gives both individuals more to be upset about. I don't completely agree with the "turn the other cheek" philosophy either, as accountability is important, but I think surely we are evolved enough by now to handle our conflicts in more sophisticated and effective ways than primal revenge. As Ghandi says, "an eye for an eye leaves the whole word blind".

People often mix up justice for revenge. Revenge is burning someone's house down because they burnt yours down. Justice is instead making their responsibility to get you a new house.

You should not perpetuate an endless cycle of hatred.

Eye for an eye would in theory create a system of preventative justice where one would not commit a crime in the first place. Obviously this is theory not reality but if we all abided by it we would be good.

When this happens everyone ends up blind.
