The publication analyzes the conformity question of the personal characteristics of people convicted of terrorist crimes with the main characteristics of the outcasts represented in sociology. In the process of studying the general characteristics of this category of persons, which included a sociological characteristic, empirical materials were obtained that allow us to put forward a working hypothesis that persons who have committed terrorist crimes have personal characteristics that are mainly characteristic of marginals. In addition to the empirical materials of structured interviews with the studied persons, this hypothesis was supported by the materials of questionnaires, testing, as well as the results of studying all the available materials characterizing them, including the texts of court decisions (sentences). Thus, according to the results of a study of the sociological characteristics of persons convicted for terrorist crimes by comparing their own results with the available theoretical and practical results of studying the emergence and manifestation of structural marginality, it was found that the studied persons do indeed have sociological characteristics characteristic of the marginalized. It has been established that most of the main sociological characteristics, conditions and situations inherent in persons subjected to structural marginalization, identified in the studies by leading sociologists, are present in the structure of the personality of people convicted of terrorism. This state of affairs opens up new possibilities in determining and implementing a corrective, corrective impact on the personality of those convicted of terrorist crimes.
