THREE:Some persons have maintained that a crime, that is, an action contrary to the laws, is punishable wherever committed, as if the character of subject[193] were indelible, or, in other words, synonymous with, nay, worse than, the character of slave; as if a man could be the subject of one kingdom and the resident of another, or as if his actions could without contradiction be subordinate to two sovereign powers and to two legal systems often contradictory. So some think that a cruel action done, say, at Constantinople is punishable at Paris, for the abstract reason that he who offends humanity deserves to have collective humanity for his enemy, and merits universal execration; as if judges were the avengers of human sensibility in general, and not rather of the covenants that bind men together. The place of punishment is the place of the crime, because there, and there only, is it a compulsory duty to injure an individual, to prevent an injury to the public. A villain, but one who has not broken the covenants of the society of which he was not a member, may be an object of fear, and for that reason be expelled and exiled by the superior power of that society; but he cannot be legally and formally punished, since it is for the laws to avenge, not the intrinsic malice of particular actions, but the violation of compacts.Against this general uncertainty of punishment, which no severity in the law can affect or make up for, the only certainty of punishment dependent on the law is in the event of conviction. But even this certainty is of a very qualified nature, for it depends on sentiments of due proportion between a crime and its penalty, which in no two men are the same. Every increase of severity in punishment diminishes its certainty, since it holds out to a criminal fresh hopes of impunity from the clemency of his judges, prosecutors, or jury.
