It would be nice if this were the case. It is still just a dream. There is not justice for all. If you watch closely justice can be purchased. Justice can be distributed differently to different people. I still think that having that as the ultimate goal is good thing. I do not believe it will happen in my lifetime and I can hope for the next generation.
On the other hand I am not sure the same punishment should be given to everyone. It seems like a true punishment would be personal. Some people are pleased with the punishment they receive. I also know of times when people were even aware they had been punished.
