@Fermi he was literally just a kid who went through trauma and abuse, it's too much to expect that a kid will have emotional regulation and be always rational. He was grieving, shouldering all the responsibility for his sister and family, dealing with trauma, school and a lot of other complex emotions. Ofc it was wrong to lash out like that but still, it's totally understandable and again, he was just a kid who didn't know how to deal with everything that was happening to him,
