Can Justice go to far?

In Wednesday's class, we were presented with the short film, "White Bear." It was about a woman, who name we learned was Victoria, woke up in an unknown area from what seems to be attempted suicide. While trying to find out who she is and what happened to the world, she was quickly chased by a man who was armed. That first encounter is what started Victoria's terror in this weird city. During her whole terrifying journey and encounters, what made it even stranger was the people who were mesmerized by a signal on their phone. They were called "onlookers" and was addicts to filming and watching anything they saw, including victoria's chase. However, I would like to talk about the twisted ending that we and Victoria's was met with. Upon her capture, she was given the truth. The truth was that her entire day was a lie and that it was her punishment for videotaping her boyfriend inhumanly torturing and murdering an innocent child. After further torture, she was sent back to the home where it all started so her memory can be erased and start the day again. Now my question is, is this really Justice? In my opinion, I do not believe it is. However, do not misunderstand me when I say that. I completely believe that she deserves a well-deserved punishment for what she did. Honestly, I feel like she deserves exactly what she got in the short film. From having everyone video her with anyone intervening, putting her in constant fear, and eventually putting her in the same pain as the little girl, is a punishment I think is well needed. But, to do it excessively, is going too far. At the end of the movie, we saw how many times they made her repeat this day and it was no less than two and a half weeks. I do not understand why they were doing that unless they were making some type of noticeable profit from it or was enjoying it. What they doing is, to me, nearly inhuman or is. A better way to use the method they showed is to do exactly what they did to her for the first day, and the second and third day maybe put her under the pain of the girl. Then put her in prison. To me, that sounds like direct justice without pushing the borderline of being inhumane. At least this way, she gets exactly what she deserves and have to live with it for the rest of her life.
