He may have ADHD but it's more probably he has some kind of PTSD stemming from from the trauma in his childhood. The symptoms are very similar to ADHD but medication tends not to be as effective (if he's even taking medication) and there's more success in going into therapy.He needs to learn respect for human beings, rather than treating people like crap and then pretending it is because he cares or blaming ADHD (very convenient thing to blame it on as can't question mental health, it is a loophole for him in my opinion)
