Hypothetically speaking, what do you think should be done to a criminal who doesn't remember his crimes? Lets say, to help you get a perception, that his crimes were of great magnitude, like death roll worthy, and that his memory was not erased by a feeble disease. He took some kind of special pill designed to erase his memories specifically about his crimes, and former life.(Remember, this is only hypothetical)

What would you say should be done to him? I personally think he should be left alive, with supervision.
