I don't know if this will be helpful to you, but I'm throwing it out there. In a consequentialist, utilitarian moral system, revenge cannot be a moral good on its own. If a universe where one person gets hurt is worse than a universe where no one gets hurt, a world where two people get hurt must be worse still. So if you're utilitarian, you believe in justice as a means to prevent crime. Punishing people can act as a deterrent, imprisoning people can separate them from would-be victims, and rehabilitation can prevent future crimes. Some people aren't consequentialists, but retributivists. They believe that deserved punishment is innately good. A universe that is fair is one in which those that cheat are issued handicaps to balance that out- think the reckless driver who gets pulled over frequently enough that it doesn't buy them any time in the long run. A fair universe is morally preferable to an unfair one. This also makes sense, though it's somewhat at odds with the utilitarian perspective.
