It's also about intent. If you don't have it in you to literally tear someones throat out and stomp on the remains, you prolly shouldn't mess with someone who does. Most people realize their mistake too late. Sometimes it takes a real beating to realize you aren't as good as you think you are. You may have amazing skill, but if you don't have it in you to serve up that kind of brutality, you should stick to the kwoon and keep your mouth shut everywhere else.
