Jamie killed Katie due to a combination of personal and social factors, including his low self-esteem, perceived bullying, and exposure to toxic online incel ideology. He reportedly asked Katie out after she had been humiliated by the circulation of topless photos at school, but Katie rejected him and mocked him publicly, even labeling him as an incel. This humiliation, combined with Jamie's immersion in misogynistic beliefs and a warped sense of entitlement, triggered a violent and angry response in which he stabbed Katie multiple times. Despite clear video evidence, Jamie initially denied the murder, likely due to shame and his youth. Over time, he comes to accept responsibility for his actions and the devastating consequences for his future.

Factors Leading to the Killing

• Jamie's lack of self-esteem and bullying experiences at school contributed to his fragile mental state.
• Katie's rejection and public mockery, including calling Jamie an incel, deeply wounded his ego.
• Jamie was radicalized by online incel communities, where misogynistic and hostile views about women fueled his distorted thinking.
• Jamie perceived Katie's vulnerability (after the revenge porn incident) as a chance to gain her affection, but rejection led to rage and violence.

Psychological and Social Context

• Jamie's denial of guilt stems from intense shame and his limited emotional maturity as a 13-year-old boy.
• The show explores themes of masculinity, teenage mental health, toxic online culture, and the complexities behind youth violence.
• Jamie's initial denial and later acceptance of guilt highlight his internal struggle and gradual awareness of his actions' severity.

This explanation positions Jamie not simply as a "psycho," but as a tragic figure shaped by a toxic social environment and his own struggles with identity and belonging.
