Just because he had a friend, some friends, doesn’t mean he wasn’t tormented.
I guarantee you he was.
One doesn’t set out to murder a school just ‘cuz.
This is the result of a slow building rage that boiled over.
Not necessarily. I work with a 7 year old kid who is emotionally disturbed. The other kids will still play with him when he's not angry or screaming and yelling, even after they've seen him hit and bite their friends.
They don't bully him, he bullies them. He needs help and the school district is passing the buck to save a buck.
Oh, and this 7 year old has already said he'd like to set the school on fire so he can burn up another student I work with (who is a sweetie).
