My qualms with "lethal" moves in martial arts, is that I honestly do not think they are practical, other than in true combat (like war). Now, before I get blasted by everyone for saying that, allow me to state my reasons, and give a disclaimer. I have not ever been in a life or death fight, nor do I know anyone that has. Perhaps this is due to my living in a smaller, quiet community, but I really believe most fights outside of the dojo are not true life or death fights. This being true, breaking arms, wrists, knees, elbow, kicking people's head in, or gouging their eyes out is overkill, in my opinion. One can beat down another person without disabling them for life or killing them. If truly the fight is a matter of life or death, then by all means, do what you must, but if not, then there is no reason to pull out all the stops. Not only may a person end up crippled with a bad knee for the rest of their life, but performing lethal moves is a good way to end up in prison. Kicking and punching may or may not end up in assault charges, depending on the circumstances, but poking in a person's eye and breaking their arm at the elbow will almost certainly land you in prison if the fight were just an ordinary brawl. Now for my disclaimer. I respect all martial arts, for different reasons, and I respect all practitioners of martial arts period. I am not knocking San Soo, or any other martial art here. What I am stating is that I do not think that lethal martial arts are always the best for fighting. They do, however have their place, and definitely have their worth. It is just my belief that they are not always necessary.
