I think it could, but that is my 2 cents.
A person able to triumph over conflict with resolution is something I think many warriors seek to attain. Though I will be going into the military, more than likely as infantry... I can't help but envy the medic. There is a very dear person to me who I have known since before even really remembering, who I recall challenging me to a fight in a middle school bathroom... who is now a successful rei ki healer. I envy those who can help others, and I hope someday I might be able to practice martial arts in such a way to help heal... but lofty goals are just that.
I think many know that there are things they could do if they sought it, but for me, something just tells me medicine isn't what I'm meant to do. That was my father's role, who is a doctor. Mine is the opposite in a sense, though with the tempering of knowing when to use it. When I study the body, my first analyzation is how it can be used to damage, or control, and though I abhor that part of me, I know it is something I am not terrible at... and maybe someday might even excel at. I'm young, so there's a long way to go, and a lot of moral cleanup I've got to do before I even consider myself really ready, or worthy to open the doors to any school of my own. But... someday.
It is hard to ask people what a warrior is, without asking what it is that makes them a warrior. All warriors are fighters... but the inverse is not always true. But there is an in-between of sort, a fine line of spirituality I've found many people, who truly care about the martial arts, possess. I don't say Martial Arts is my religion because it is something I go to a temple of pray over- it is a way of life I've found to have vastly improved my own. Something I know can, and has saved my life before, and I know I can use to help others.
So to me, a warrior spirit is less about fighting, and moreso the powerful will, and confidence has in oneself, and their abilities. To know when to fight, and when they do, with everything they have.
I try to help others- and most martial arts tends to favor the moral side of good. Oddly, I do not think, necessarily that martial arts has a particularly moral slant- and hence is how it can be abused to hurt.
I think there may be a lot of warriors in today's armies who do not possess warrior spirit, no matter how you define it. Which might give the martial artist the advantage.
And even then... all this still begs the question of how 'honor' plays a role. There are a lot of philosophical questions to ask, and seek answer for, before really being able to determine what a warrior is, and whether martial artists not only can be categorized, but should. And that last might just be decided by what a warrior spirit is, and how it is a part of martial arts.
Apologies for the verboseness.
