According to statistics obtained by my father, the share contributed to the sum total of criminality by this latter type is only 33%, which appears to be a magic figure for the criminal, since it corresponds to the percentage of the histological anomaly discovered by Roncoroni and to that of all important anomalies, including those of the field of vision. But besides this percentage of born criminals, doomed even before birth to a career of crime, whom all educational efforts fail to redeem and who therefore should be segregated at once; besides the epileptic, hysterical, and inebriate lunatics and those insane from alcoholisation, of whom we have already spoken, there remain a number of criminals, amounting to a full half, in whom the virus is, so to speak, attenuated, who, although they are epileptoids, suffer from a milder form of the disease, so that without some adequate cause (causa criminis) criminality is not manifested. The inhibitory centres are somewhat obtuse, but not altogether absent, so that a healthy environment, careful training, habits of industry, the inculcation of moral and humane sentiments may prevent these individuals from yielding to dishonest impulses, provided always that no special temptation to sin comes in their path.
We have said that education is not sufficient to convert a criminal into an honest man. Conversely, trials and difficulties and the want of education are powerless to make a criminal of an honest individual. Hypnotism, the most powerful means of suggestion possible, cannot induce a good man to commit a crime during the hypnotic sleep, but vicious training has an enormous influence on weak natures, who are candidates for good or evil according to circumstances. Such individuals were classified by my father as criminaloids.
Physical Characteristics. Criminaloids have no special skeletal, anatomical, or functional peculiarities. As the criminaloid represents a milder type of the born criminal, he may possess the same physical defects in the skull, hair, beard, ears, eyes, teeth, lips, joints, hands, and feet, as well as all the sensory anomalies, lessened sensibility to touch and pain, hyper-sensibility to the magnet and barometrical variations, etc.; but all these anomalies are never found in the same proportion as in born criminals; that is, criminaloids never manifest the aggregate of physical and psychic peculiarities which distinguish born criminals and the morally insane. On the other hand, we find in criminaloids certain characteristics, such as premature greyness and baldness, etc., which are never exhibited by the born criminal. The real distinction between the criminaloid and the born criminal is psychological rather than physical.
Psychological Characteristics. The difference between born criminals and criminaloids becomes apparent directly on considering the age at which the latter enter on their anti-social career and the motives which cause them to adopt it. While the born criminal begins to perpetrate crimes from the very cradle, so to speak, and always for very trivial motives, the criminaloid commits his initial offence later in life and always for some adequate reason.
A criminal of this attenuated type, a certain Salvador, without cranial or facial anomalies, had led an honest life for many years, but on returning home after a prolonged absence on business, he found his house ransacked by his wife, who had deserted him. From that time he seems to have deliberately adopted a career of dishonesty, as the leader of a band of thieves.
In another case, an engraver who showed no pathological anomalies, except excessive frontal sinuses, was ordered by a society to strike a medal for them. This happened to be exactly similar to a coin current in his country and the coincidence incited him to the making of counterfeit coin.
But the most characteristic case, which aroused much interest in its time, is that of Olivo. He was a man of handsome appearance, with normal olfactory acuteness and sensibility to touch and pain. He had, however, inherited from neurotic and insane forebears secondary epileptic phenomena, which subsequently developed into convulsive epilepsy, and certain indications of degeneracy (facial and cranial asymmetry, abnormal capillary vortices and length of arm, scotoma in the field of vision and exaggerated tendinous reflex action). Up to the age of thirty he led an irreproachable life; in fact, he was scrupulous to excess, and this, coupled with pronounced conceit and stinginess, was his only fault. He married a woman of common origin, who was not really depraved, but she was coarse and unfaithful, and, worst of all in his eyes, unscrupulous and wasteful. These defects, and her habits of lying and trickery embittered the poor man's existence. One night, feeling very ill, probably owing to an approaching seizure, he appealed to his wife for assistance and received an unfeeling reply, whereupon he sprang out of bed, picked up a knife and stabbed her. Afterwards he fell into a deep sleep. In order to obliterate all traces of the crime, he cut the corpse into small pieces, packed it into a portmanteau and threw it into the sea. Two months later, when he was arrested, he immediately made a full confession, showing deep repentance and sincere attachment to his victim, whose merits he celebrated in a poem of his own composition. At the trial, he made no attempt to defend himself; during the hearing of evidence, which appeared greatly to agitate him, he was seized with an epileptic fit. He was absolved by the jury and returned to his former peaceful occupation of bookkeeper, nor did he again come into conflict with the law.
Reluctance to Commit Crimes. Another trait characteristic of criminaloids is the hesitation they show before committing a crime, especially the first time, when it is not done, as in the above mentioned case, during an epileptic seizure.
Feuerbach's fine collection contains a description of the brothers Kleinroth, whose father cruelly ill-treated and starved his wife and family while lavishing his money on low women and their bastards. The sons were unwilling to run away and leave the invalid mother to bear the brunt of her husband's fury, and while they were in this terrible situation, a certain individual offered to assassinate their tormentor. After great hesitation this offer was accepted; when arrested, the youths immediately confessed their complicity and manifested deep repentance.
Confession. The criminaloid is easily induced to confess his misdeed.
