I do martial arts, and I do it with the knowledge that, its not a sport or something for fun. Its to fight, and the purpose of ANY fight is to defeat the opponent....and well the only true way to defeat someone...is to kill
Neo, people don't really kill people and thing again with the martial arts. Is modern arts that people does be using these days.
Many martial arts were developed NOT to actually fight and kill, but rather, as self-defense.
