Punishment should not be about rehabilitation. It should be about justice. If the criminal can be rehabilitated, then fine. But it should never be the goal. Furthermore, long term prison sentences are definitely cruel and unusual. I would much prefer fines and corporal punishment for minor crimes and the death penalty for serious crimes. A prison sentence is much more likely to destroy a man’s life than a good whipping. Also depriving someone from his freedom for life is less merciful than putting him out of his misery in seconds.
