I wish the best for him. I will not give a diagnosis, but, I see how it would be hard for him to be disciplined correctly. Maybe the behavior is in his genes. Or, maybe hes feeling emotional inside and he has to take it out on others. All bullies do. And he might feel that hes not good enough to have a real job or anything because he doesnt feel like he deserves love. Then again Im not diagnosing. I wish the best for him and the family.
