I have to say that there is so much proven scientific research on this drug for a number of illnesses and the affects are exceptionally positive. I recently had to do research and write an article on it for a client. Taken in moderation it can be very beneficial for many conditions. However, it has a calming affect, especially for anxiety and many vets are currently treated with it. I did not come across any evidence of it inducing anger or aggression. It even reduced an epilepsy condition of over 300 seizures to 1 a week. I would not despair, but rather do your research and chat to someone who knows so that you have a clear picture of the affects and exactly what this boy is doing and why.
