The punishment for doing crimes is being stripped of your freedoms, being unable to move around, having every moment of your day dictated to you rather than your own choice, being unable to live with your family, all of the simple joys of life, and the very basic component of being in control of yourself are taken away. There's no need to torture people on top of that.
What about the simple joys of life that were taken from their victims. Again, you are victimizing the criminal. If they want to keep their liberties, they should abide by the law.
