THREE: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.Persons guilty of lesser crimes are usually either punished in the obscurity of a prison, or transported, as an example to nations who have given no offence, to a distant and therefore almost useless servitude. Since the gravest crimes are not those which men are tempted to commit on the spur of the moment, the public punishment of a great misdeed will be regarded by most men as strange and of impossible occurrence; but the public punishment of lighter crimes, to which mens thoughts more readily incline, will make an impression, which, at the same time that it diverts the mind from them, will restrain it still more from crimes of greater gravity. Punishments should not only be proportioned to one another and to crimes in point of force, but also in the mode of their infliction.
