The other day a friend of mine remarked, "A coward is more dangerous than a brave man". He was referring to some workplace backstabbing, but I thought it applied equally well to the martial arts, in a literal sense. In a self-defense situation, the most dangerous aggressor may be the coward. Similarly, in defending yourself, your best bet may be to resort to deception and any devious, underhanded, dirty tactic you can. Still everyone seems to reference sporting combat to justify the effectiveness of their art as self-defense. What about you, do you fight like a hero or a coward?
