I think you are well intended, dg, but you are not the man and you do not truly know what motivated him.  In my experience, it is females who are overly into power/control.  If we as a society were interested in rational resolution of problems we would perform surgical organ removal and see if indeed it is effective, more effective even that spending millions of dollars keeping a human in a cage for decades.  Perhaps you have mentally stripped the perp of humanity and are comfortable with even the most cruel and abusive treatment.  Decades in a cage is probably the most inhuman cruel thing that can be done to a person.  Better to try organ removal and on reoffense remove the hands or other parts that enabled it.
