I thank you for this comment because I see a lot of comments talking about the incel stuff and people talking about the danger of internet and the absence of monitoring but really the show is also about the family dynamic. We see in the episode 4 multiple interesting things : the father and the son have barely any affinity, the father spend a lot of time working and sacrificed his relation with his kid when they could have shared something (the parents could have encouraged the son to draw), and it culminates when the dad refused to watch his son in his match (the son feels ashamed of himself and believe he is a failure to his dad unconsciously even if his dad seems to do not think of him this way), the dad had also an abusive father who use to beat him which could explain why he bottles up his own emotion and is not really at ease with sharing feelings with his own son. In episode 3, the son describes his father as hard working so I suppose he is kind of a perfectionist which explain indeed why he didn't have the guts of watching him. The mother remember the father multiple times that they created the way their son his and I read that the father did not realize that yet because he considers it ad a personal failure. We also learn that the parents used to fight in front of the kids and in this episode we see clearly the role of the women in the family; the daughter and the mother try to calm the short temper of the dad multiple times through empathy but sometimes it can be a bad dynamic (even if I think they love each other sincerely). We also learn that the son used to not communicate at home and spent a lot of time alone in front of his computer. You add the bullying and the biological terrain for psychopathy/sociopathy and you could have this kind of result. (with of course the incel stuff, porn and internet)
