We can now see the origin of the idea that the true end of punishment is the reformation of the criminal. This idea merely emphasises the most humane element in resentment, the demand that the offender's will shall cease to be offensive. The principle of reformation has thus itself a retributive origin. This explains the fact, otherwise inexplicable, that the amendment which it has in view is to be effected by the infliction of pain. It also accounts for the inconsistent attitude of the reformationist towards incorrigible offenders, already commented upon. Resentment gives way to forgiveness only in the case of repentance, not in the case of incorrigibility. Hence, not even the reformationist regards incorrigibility as a legitimate ground for exempting a person from punishment, although this flatly contradicts his theory about the true aim of all punishment. Thus the theories both of determent and of reformation are ultimately offspring of the same emotion that first {89} induced men to inflict punishment on their fellow-creatures. It escaped the advocates of these theories that they themselves were under the influence of the very principle they fought against, because they failed to grasp its true import. Rightly understood, resentment is preventive in its nature, and, when sufficiently deliberate, regards the infliction of suffering as a means rather than as an end. It not only gives rise to punishment, but readily suggests, as a proper end of punishment, either determent or amendment or both. But, first of all, moral resentment wants to raise a protest against wrong. And the immediate aim of punishment has always been to give expression to the righteous indignation of the society which inflicts it.
