My brother got his hour of fame on the news today I guess being a school shooter has its perks.
I don't think you should glorify his actions.  Are you certain this is the way you want to speak of your brother?
Yes, why? He's is a great guy and I'm so proud of him. It's not his fault he was bullied, that's an excuse.
It's insensitive to support your brother for his shootings at school. You should put yourself in victims shoes and think how you would feel being terrorized by a school shooter.
