This is really awful. I’ve worked with boys in a women’s refuge and they have been through hell and seen the worst kind of intimate violence close up and (horrifyingly often) sometimes forced to be the perpetrator. It leaves them (not always by any means) angry, sad, confused about what it means to be male, deep shame, believing they are bad and also exposed to horrific things like rape, violent phonography etc.
I’m not excusing what this teen has done in any way, but for societies sake as well as his own he needed therapy aged 8.
Refuges are notoriously underfunded and CAHMs is a joke in most areas. We all pay the price.
