TWO:Two other fatal consequences flow from the cruelty of punishments, and are contrary to their very purpose, the prevention of crimes. The first is, that it is not so easy to preserve the essential proportion between crime and punishment, because, however much a studied cruelty may diversify its forms, none of them can go beyond the extreme limit of endurance which is a condition of the human organisation and sensibility. When once this extreme limit is attained, it would be impossible to invent such a corresponding increase of punishment for still more injurious and atrocious crimes as would be necessary to prevent them. The other consequence is, that impunity itself arises from the severity of punishments. Men are restrained within limits both in good and evil; and a sight too atrocious for humanity can only be a passing rage, not a constant system, such as the laws ought to be; if the latter are really cruel, either they are changed, or themselves give rise to a fatal impunity.
