One of the main ideas of this study is that the creation of a meaningful theory of crime in general, a conscientious study of the "crime problem" and the qualified application of knowledge to its solution is impossible without taking into account a huge number of factors that influence a person's life path at various levels: from the personal characteristics of the individual himself to factors related to his family, peers, school, neighbors, circle of acquaintances, culture and society as a whole. The formation of the personality of a criminal occurs at each stage of his formation in society, and an extremely important task is to identify and understand what exactly lies at the origins of the commission of a series of crimes, as well as what specifically prompted a serial criminal to commit his first crime, what could be the starting point for actions that resulted in the injury and (or) death of several to several dozen people. An attempt to consider the criminal behavior of serial criminals in the prism of a psychosocial approach - crime from a psychological point of view. Methods: The present study used the dialectical method, analysis, synthesis, induction, deduction, synchronous and diachronic comparison, historical method, as well as specific scientific methods: formal-legal, comparative-legal, etc. The study of this topic is a vital task for the whole society as a whole, since its well-being depends on it. "The problem of "maniacs" exists as long as civilization exists."
