This case study delves into the aggressive conduct and criminal goals of Master B, a 15-year- old adolescent who has been detained in a juvenile facility for five months on murder accusations related to a family property dispute. Master B testifies to deliberately killing another individual 16 times in retribution, motivated by strong resentment and family loyalty. His violent history includes a notable episode of aggressiveness at school, in which he beat an acquaintance for verbally assaulting his girlfriend. Despite his activities, Master B shows no regret and openly professes his desire to become a gangster, claiming that he intends to do more violent acts. His separation from cultural standards, academic failure, alongside lack interest in participating in rehabilitation are evident, despite the fact that he participates in academic endeavours and recreational carrom only sometimes whilst in the juvenile centre. Master B's treatment consists of planned learning opportunities and behavioral interventions; however, his persistent antisocial tendencies indicate the requirement for specific strategies that incorporate Cognitive Behavioral Therapy (CBT), anger management, and familial therapy to address his violent impulses and criminal ambitions. Anger management, logotherapy, interpersonal training, and criminal thought treatments are all possible methods for dealing with such conduct.
