I don’t think that man has that responsibility.
So yes, you'd oppose such a device being used on prisoners guilty of heinous crimes?
Well, punishment is a good start...
When you are punished by your parents, you learn that what you did was bad and hopefully you don’t do it again, right?
My parents punishments consisted of confinement and restrictions. If I did something bad, I was confined to my room, and my access to sources of entertainment and comfort were restricted for a given period of time. Indeed, I did learn my lesson in this way, and modified my behavior.They certainly didn't subject me to pain and torment, and had they, I'd probably have learned a very different lesson indeed.
How does one begin to rehabilitate people who don’t take responsibility for the wrongs they commit?
That's an interesting question, given not all criminals fail to take responsibility for their crimes. Some are quite willing to own up to their deeds, but doing so affords them no special treatment or consideration. Some people who commit the most heinous crimes literally aren't responsible for their actions, such as Vincent Weiguang Lee, an undiagnosed schizophrenic who in a psychotic episode beheaded and cannibalized a fellow passenger on the grey-hound bus he was taking. By many standards of justice this man would deserve the severest possible punishment, but because he had no idea where he was, who he was, what he was doing or why he was doing it, he was deemed not criminally responsible and sent for psychiatric treatment instead. The psychiatric treatment took, he satisfied his doctors that he'd regained his sense of reality and was no longer a public danger, and so he was released from his maximum security psychiatric facility and is now essentially a free man. A grave injustice in the eyes of some, the morally responsible thing to do in the eyes of others.
