Whether or not he was mentally ill before he went to prison, the time he spent there provided no rehabilitation or treatment for Fitzsimmons. The fact is that building more prisons, stuffing them with people and being tough on them has little or no impact on crime rates. It doesn't mean that we shouldn't punish them.
