The topic of serial killers is incredibly relevant today, because these people appear everywhere and spread fear and death. Today it is unknown exactly who they are and how many lives have already been taken, and how many more will be taken… The exact number of victims, of some already caught and punished killers, is unknown. The difficulty is also in "hunting" for such people: until a pedantic and attentive maniac makes a mistake, it is difficult to catch him, because he is competent in how to plan the murder, so as not to leave evidence. Unfortunately, investigators, psychiatrists and psychologists still often misunderstand the thinking of such individuals, which directly affects the quality of the investigation process. Ukraine, as a democratic state, recognizes people, their life and health, honor and dignity, inviolability and security as its top priorities. In fact, this is the greatest social value. Everyone has the inalienable right to life. It is the legal protection of a person from criminal encroachments on life and health, as the most important social values, that the state should provide through its law enforcement agencies. We are in a state of prolonged military intervention amid an even longer pandemic with ever-increasing threats of social instability and existential personal and social crisis. All these factors increase the general state of increasing social aggression, which in turn can stimulate and stimulate (as recent events in Bucha and other places of hostilities show) people who are on the verge of pathological aggression to active action.
 Therefore, the chosen topic of our research, namely "Psychological portrait of a serial killer in the intrasubjective perception of the average citizen" may reveal new aspects of this problem.
