How do you define honorable fighting or honorable combat (whichever you choose to call it)? As martial artists, we believe to some extent that violence is appropriate. In what forms do you considering it appropriate and/or honorable? Do you ever consider it honorable?
Before answering the question, one needs to define 'honor'.........sometimes we make the mistake of thinking it's something like morality. The reality is that honor is about duty and obligation.
Therefore, our sense of honor is about our ability to fulfill our duties and obligations, whatever they are.
At it's core, what is fundamentally honorable is what is considered the fundamental aspect of manhood........at it's fundamental, manhood is about the ability to protect ones land, women and children..........hence, those obligations make actions toward those ends 'honorable', and actions that are detrimental to those ends 'dishonorable'.
Add to that in a larger society many take on roles and societal protectors.......military and law enforcement, for example, have taken the responsibility and duty to protect the society and uphold a code of conduct.........actions that further those ends are 'honorable'.......those actions that are detrimental, such as cowardace, are 'dishonorable'.
Is fighting every honorable? Certainly, if it is engaged in as a furtherance of duty or obligation.
Not all physical confrontations are about 'honor'.....self-defense, for example, wouldn't strictly be about honor.......defending another would.......but not being an issue of honor doesn't necessarily make them 'wrong'.........self-defense is absolutely moral and just, it's just not strictly an act of 'honor'.
