I have been in the martial arts for 20 years. I like to think that as your progress in whatever art you choose to follow that you will develop a level that allows your character to shine through.
I have noticed that people who have spent many years studying budo can and will exhibit extraordinary technique and control in the same instance. Whether or not a technique kills, maims, or controls is a matter of choice to a person at this level.
I would like to believe that this is pervasive through most of the martial arts.
My training in other arts, IMHO, has helped me provide a more realistic environment for my students when stepping outside traditional kata.
