Since there is no need to give further support of the practical application of the concept in making the world a safer place, I will go ahead and talk about the application on a deeper emotional level. I think the way we are judging is wrong. An eye for eye may seem barbaric, but a justice system based on presentability and propriety merely makes us appear more civilized rather than helping human beings with real feelings. Justice should then be based on inherent correctness. If we study the universe and physics, an eye for an eye is a perfectly sound and objective course of events. Every action creates an equal and opposite reaction and energy can neither be created or destroyed. If a person is raped, tortured and murdered and the same fate is not reflect back upon the victimizer, the victim's pain does not dissappear but very much lingers in an unbalanced equation, creating unaidable mental, spiritual and physical breakdown. Such pain cannot simply be swept underneath the carpet of political correctness and according to the laws of the universe, will manifest itself in later generations. The carpet will eventually become a mountain. Basically what I'm saying is, energy cannot be destroyed, a victim without justice is indeed creating stress in society that will eventually snap. The idea of revenge is a natural response and what goes around comes around follows a very real universal law. Any opponent of an eye for an eye resolution should try telling an atom not to explode back when hit by a zooming electron.
