When people show too much ego, there are bound to be resentments. I think that sometimes martial artists are too egotistical and can be unwilling to be humble or submit themselves to anyone else. They get stuck by the mark of self. Greed, anger, stupidity, pride, delusion - these all get in the way of true cultivation. To cultivate yourself higher, you must rid yourself of these afflictions.
Martial arts are a vehicle for self awareness, to cross over from ignorance to wisdom.
It's not about ego or killing or beating another - it's about destroying the ego. My concern about people presenting material in this way is that it gives a wrong message to current and future generations of people. Many Secret Societies today have underground dealings, very different than perhaps the original ideals or altruistic concerns of some of the founders of these societies. It is a danger, and as a responsibility to our ancestors and our future descendants, we must behave properly and pass on the correct example. We must differentiate ourselves clearly from such people, as it can cause young males to behave improperly and less than constructively in society today.
