This is truly a masterpiece. The characterization of the boy, the social context he is in, his loneliness, the lack of guidance and good role models, the indoctrination he falls into, the violence he already carries inside of him and that no one in his life can adress, the family generational trauma, it's so well written and portrayed very realistically. What's terrifying as well is the fine line they depict of him as a child while at the same time having already commited a murder and being perfectly aware of it, yet having no empathy for the victim.
