The "perfect" justice system

Recently, we watch a video in which "Justice" was being done to a young female child who had been raped and burned alive by a man, while his girlfriend recorded it. To recap. the man committed suicide while in custody and the woman was left to pay for the crime. As the video commences, and all that was previously mentioned is not yet revealed, the spectators in class, that being us, is puzzled at the scene of a woman being hunted while the rest of the neighborhood just watches and records her. We as the outer spectators are left asking why they won't help her, infuriated even. We can't come upon a valuable reason as to why nobody is helping her, we feel sympathy and sorrow for her. Somehow though, after all is revealed and her boyfriend's crime is conveyed, we seem to lose that sympathy and feel like justice was actually made on behalf of the innocent little girl. Was it really though? was "justice" made? or did the attempt to bring justice morph us into monsters? Who decided what constitutes as justice and what does not? The reality is that trying to bring justice to the child by mentally breaking down the person who was not the one that raped and burned the child is morally wrong. It seems as though the punishment is for more than simply the child's justice, in the punishment, deep down in the very root of it lies a deeper reason. The fact that "justice" couldn't be done by making the guy pay, brings about the idea that the woman is not only paying for her part, she is being punished for both her and her boyfriend. When we, the spectators, decide to participate in this event, does that not make us just like her? Why then aren't we punished for it? If you analyze it quickly, we willingly volunteer to take part in her punishment, to take on the role that she had as to in some way teach her a lesson. But what is really happening is that we begin to enjoy it, and while we tell ourselves that it's simply for justice, the ultimate truth is that we do it for no other reason than the simple pleasure of it. We degrade ourself to a lesser value than hers, because now we try to use her method on her and to our convenience change the moral values in order to lack guilt. We become hypocrites and in the process deny that the true monster is not the woman, it is us. The real monster is the society as a whole, because since her part in the incident was of an individual person, it is viewed as unrighteous and demonic; but it seems as though Society seeks that moment in order to let out the monster inside, in order to act in such a way and then justify it through the justice system. Basically one person tortures another, it's a severe and undesirable crime, but when society does it as a whole, it is the morally right thing to do in order to keep the justice system "balanced."
