Abstract
This paper delves into the definition, characteristics, causes, and manifestations of malicious retaliatory homicide. It utilizes the differential association theory and the theory of self-identity to deeply investigate the psychological and social roots behind these criminal behaviors. This includes the mechanisms of learning and imitation within social groups, and how individuals construct and maintain their self-identity in society, as well as its impact on behavior and emotions. Finally, the paper proposes a series of preventive measures to reduce the occurrence of malicious retaliatory homicide. These measures include strengthening social support systems, implementing educational interventions, and providing mental health services. These strategies are aimed at comprehensively addressing this complex criminal phenomenon to lower its frequency and severity.
