Society is afraid of loners, loners that it makes. They are seen as losers as we are divided into winners and losers. What is there to win depends on what we appreciate.
When you bully someone and that someone attacks you, it probably was not what you expected was it. I encourage people to learn to defend themselves. When somebody hits me, I hit back and it very possibly hurts. Still it is not to take a life as bullies want to do themselves. They are the extreme violators and in need of help.
