I don't believe a student that threatened to shoot up my school can change
What do you think might happen to him after he made these threats?
I think he will eventually follow through with his plans
I understand the fear behind someone like that. You should be cautious of people who make violent threats towards others.
It's too late for that. If someone does crazy things, it's a waste of time to try to make him/her change. I think that school shootings are an act of bravery.
School shoots are done by cowards who arm themselves and  attack kids who are unarmed. It's an act committed by deranged individuals. Thinking this is brave would make many people question your morality.
