Although persons who commit these acts are often in no wise distinguishable from ordinary individuals, both criminals and criminaloids are more often guilty of such offences than are normal persons, who instinctively avoid coming into conflict with the law.

The difficulty of judging these misdeeds lies in the necessity for careful weighing of the motive which gives rise to them, whether, that is, they have been unwittingly committed by an honest individual, or whether they are but an item in the long list of offences perpetrated by a criminal. This differential diagnosis should be based principally on the antecedents of the offender.

To this group belong also the authors of more serious infractions of the law that are not generally considered such at the time, or in the district in which they take place. Misdeeds of this nature are: thefts of fuel in rural districts, poaching, the petty dishonesty current in commerce and in certain professions, and in countries where secret societies like the camorra at Naples and the mafia in Sicily, exist, a connection with such organisations, which to a certain extent is necessary in self-defence. Such, too, are theft and homicide during revolutions, insurrections, wars, and the conquest and exploitation of new territories and mines.

Rochefort and Whitman have pointed out that during the gold-fever in Australia and California there was an enormous increase in crime. Individuals of good antecedents engaged in deadly struggles for the possession of the most valuable territories, and unbridled orgies followed these bloody affrays.

During the expedition of Europeans to China in 1900, looting was carried on by soldiers of previously blameless career.

Criminals of Passion

This type of criminal, if indeed such he may be called, represents the antithesis of the common offender, whose evil acts are the outcome of his ferocious and egotistical impulses, whereas criminals from passion are urged to violate the law by a pure spirit of altruism. In fact, they stand in no relation whatsoever to ordinary delinquents, and it is only by a legislative compromise that they are classed together. They represent the ultra-violet ray of the criminal spectrum, of which the vulgar criminal represents the ultra-red. Not only are they free from the egotism, insensibility, laziness, and lack of moral sense peculiar to the ordinary criminal, but their abnormality consists in the excessive development of noble qualities, sensibility, altruism, integrity, affection, which if carried to an extreme, may result in actions forbidden by law, or worse still, dangerous to society.

Physical Characteristics. These, too, are in complete contrast to those of the born criminal. The countenance is frequently handsome, with lofty forehead, serene and gentle expression, and the beard is abundant. The sensibility is extremely acute; there is a high degree of excitability and exaggerated reflex action, all characteristics of the normal (or rather hypernormal) individual, from whom nothing distinguishes the criminal of passion except the anti-social effects of his action.

Psychology. Here, as in all physical characteristics, criminals of passion are scarcely distinguishable from their fellow-men, except that we find in an excessive degree those qualities we consider peculiar to good and holy persons—love, honour, noble ambitions, patriotism. In fact, the motive of the crime is always adequate, frequently noble, and sometimes sublime. Love prompts certain natures to kill those who insult their beloved ones or are the cause of their dishonour and, in some cases, even the object of their affection who proves unfaithful. Crimes of this character are the murder by brothers of the man who dishonours their sister, the murder of an infant by its unmarried mother, the murder of an unfaithful wife by her husband. Sometimes the motive is a patriotic one, as in the cases of Charlotte Corday, Orsini Sand, and Caserio ([Fig. 21]) all of whom had been persons of gentle disposition and blameless conduct up to the moment of their crimes.

This class of offender not infrequently commits suicide after his crime, or, if this is prevented, he seeks to expiate it by long years of remorse and self-inflicted martyrdom.
