As long as the justice existed, there are always been misjudging with criminal being undercharged, or uncharged, while honnest people were taken to prison unfairly. Justice though has always tried to be as accurate as possible and unbiased when pronuncing a sentence. Related to this, it is claimed that misconduct should be judged only based on the laws broken, although some say that each criminal should have a personnal jugment. In my opinion, this debate cannot properly be settled, as it will lead to both advantages and inconvenients. In this essay, I will go through both views.
