NO WAY, fantasizing about murdering the other kids is ADHD too?! A girl in 5th grade once shared a private conversation we had over skype to the whole class (wasn't even anything wild, she asked me what I thought of a guy and I was like "he's ok", but it's the principle of not sharing private stuff that got me) and I have wished for her death for at least a decade afterwards. Which, thinking back, was probably kind of an overreaction.
