Was there any sense of fairness in seeking revenge?
Imagine this situation: if somebody stabbed you, then you would stab him back. It seemed pretty fair on the surface, but when you looked deeper into it, oftentimes, that was not the case. You did not hurt anybody and were innocent, so why would you have to experience the same pain as the proprietor? The only fair treatment should be the wound on your body disappearing while the proprietor got stabbed in the same spot.
Let's try to imagine another situation: if you were killed, fairness would ensue if you were resurrected and the murderer died in your place. Only through this way could your benefits be preserved while the murderer received the punishment he deserved at the same time. However, since this kind of situation defied natural law, it was often unacceptable in the majority of places save for one—the pocket dimension.
