I can't help but wonder what the heck happened in that mans childhood to make him want to brutally murder and dismember a child, or anyone for that matter. My God! What horrific things were done to him that he chose to do such a heinous act? Other than just being mentally sick, there must be other factors throughout his life that all came together in this monstrous act.
Still, considering what he did and how he disposed of the body, he deserves no less than to have to live his life in fear of other prisoners on a minute by minute basis. He is a monster. And monsters deserve whatever horrific fate befalls them.
