How does Prison Effect Peaple that are in it.

In one of the readings we have had recently, there has been study of the effects of prision on people. I foulnd this very interesting, because in the experiment there was a prison that was created called the Stanford Prision, in which volunteers were at the flip of a coin supposed to either be a prison guard or a prisoner. After very little time, alot of corruption had happened to the students that were prisoners and even the guards themselves. Many of the prisoners became very unhumane and depressed, some even stopped eating. Meanwhile the guards themselves had fallen out of reality and became so into their role of being the guards. I cannot say that this is unfair to all the murderers, rapist, and child molesters out there because i believe that their lives should be as miserable as possible while in jail, after all it was their decisions that got them in there in the first place. It is just interesting to see how environment can effect the way a person behaves in such a dramatic way. On the other hand if people have been wrongfully charged and put in prision, I think that the way that this person may be changed is not right at all. Our prisons are bacomming more and more packed every day and the U.S. has more people in prison than anywhere in the world. This makes me think, is there a better way to discipline our criminals that could lead to better outscomes than we have today?
