I suggest you familiarise yourself with the definition of being killed in cold-blood. He was shot in the back in a premeditated attack, while posing no threat and unarmed. He left behind two sons.

If he wasn’t so good looking, nobody would care about him. The fact is, he took another life in cold-blood. He had a manifesto and a gun in his backpack. He’s not a hero and hasn’t accomplished anything through his violence.
