Maniacs are prone to satyriasis and bacchanalian excesses. They commit rape and indecent acts in public and often appropriate strange objects, hair or wearing apparel, with the idea of obtaining means to satisfy their vices, either because they are unconscious of doing wrong or because, like true megalomaniacs, they believe the stolen goods to be their own property. Sometimes a feverish activity prompts them to steal; "I felt a kind of uneasiness, a demon in my fingers," said one, "which forced me to move them and carry off something." Monomaniacs, especially if subject to hallucinations, frequently manifest a tendency to homicide, either to escape imaginary persecutions or in obedience to equally imaginary injunctions. The same motives prompt them to commit special kinds of theft and arson. Na... (see Fig. 16) murdered his friend without any reason, after suffering from delusions for one year. The characteristics of insane criminals are so marked that it is not difficult to distinguish them from habitual delinquents. They seldom show any fear of the penalty incurred nor do they try to escape. They take little trouble to hide their misdeeds, or to get rid of any clue. If poisoners, they leave poison about in their victim's room; if forgers, they take no trouble to make their signatures appear genuine; if thieves, they exhibit stolen goods in public, or appropriate them in the presence of witnesses. They frequently manifest unbounded rage and assault those present, entirely forgetting the stolen objects. Once their crime is accomplished, not only do they give themselves no trouble to hide it, but are prone to confess it immediately, and are eager to talk about it, saying with satisfaction that they feel relieved at what they have done, that they have obeyed the order of superior beings and consider their actions praiseworthy. They deny that they are insane, or if they admit it in some cases, it is only because they are persuaded to do so by their lawyers or fellow-prisoners. And even then, they are ready at the first opportunity to contradict the idea, eulogising and exaggerating their criminal acts. A full confession in court is not uncommon, and in the case of impulsive monomaniacs, epileptics, and insane inebriates, the descriptions are full of characteristic expressions, showing what was the offender's state of mind when dominated by criminal frenzy. Rom..., an impulsive monomaniac, who stabbed an acquaintance, felt "the blood rushing to his head, which seemed to be in flames." Tixier narrates that, on seeing the old man he afterward murdered pass him on a country road, "something went to his head." Frequently such criminals are quick to give themselves up to justice. _Antecedents._ Unlike the ordinary offender, insane criminals are often perfectly law-abiding up to the moment of the crime.
