Alan Moore's point is that kind of violence (oh, you just knock him out, no harm done) doesn't exist. If you knock someone unconscious, you're lucky if they only suffer minor brain damage. Someone who goes around at night and giving people brain damage (if not outright murdering them) because they broke some moral code is a sociopath. There isn't "safe, good guy" violence and "dangerous bad guy" violence, it's all lethal violence.
