So if I understand you correctly, you feel there is no role for vengeance in the modern world, also justice equals vengeance, so is there a role for justice in the modern world?
Correct. Justice had always been synonymous with vengeance. There is a societal notion that vengeance equates to some form of atonement. People pleading for justice typically desire some equal form of retribution as if it restors some kind of moral equilibrium. As long as that is the accepted view of justice I will not support it. I support more productive and rational measures.
