Therapeutic cloning? "Doc, I just don't feel right. I get so...angry all the time." "Here, let's clone you. Perhaps when you see yourself beside yourself in anger, you'll realize how destructive your anger is."

"Doc, I just don't feel right. I want to kill myself." "Here, let's clone you--you can kill the clone, see how it feels, work through the issues."

Er, not offering these as worst-case scenarios; just trying to imagine what "therapeutic cloning" could entail.
