By all this I certainly do not mean to deny that punishment, though in the main an expression of public indignation, is also applied as a means of deterring from crime. Criminal law is preventive, its object is to forbid and {199} to warn, and it uses punishment as a threat. But the acts which the law forbids are, as a rule, such as public opinion condemns as wrong, and it is their wrongness that in all ages has been regarded as the justification of the penalties to which they are subject. It is true that there are instances in which the law punishes acts which in themselves are not apt to evoke public resentment, and others in which the severity of the punishment does not exactly correspond with the resentment they evoke. The State may have a right to sacrifice the welfare of individuals in order to attain some desirable end. It may have a right to do so in cases where no crime has been committed, it would therefore seem to be all the more justified in doing so when the evil has been preceded by a warning. And yet, in the case of punishment, it is only within narrow limits that such a right is granted to the State. To punish a person could not simply mean that he has to suffer for the benefit of the society; there is always opprobrium connected with punishment. Hence the scope which justice leaves for determent pure and simple is not wide. Sir James Stephen observes:--"You cannot punish anything which public opinion, as expressed in the common practice of society, does not strenuously and unequivocally condemn. To try to do so is a sure way to produce gross hypocrisy and furious reaction."[210] Experience shows that the fate of all disproportionately severe laws which make too liberal use of punishment as a deterrent is that they come to be little followed in practice and are finally annulled. As Gibbon says, "whenever an offence inspires less horror than the punishment awarded to it, the rigour of penal law is obliged to give way to the common feelings of mankind."
