I see honor being mentioned in different contexts in movies and anime, but it was difficult for me to determine what exactly is the principle behind it.
From refusing to attack unarmed enemy, to loyalty which goes to extreme cult like dedication, to keeping your word always, to refusing to harm innocents even when battle could be lost because of it, to prioritising community over individuals and leader over community.
So I decided to make formal version of argument of this specific type of morality which I struggle with to understand because different versions of it appear everywhere.
So first, refusing to attack unarmed enemy. Unarmed enemy who refuses to fight is not a threat, at least not obvious threat.
So principle here could be to only attack those who are obvious threat to you, or in other words, those who attack you.
The opposite principle doesnt work because attacking those who dont attack you would result in attacking everyone. And we cant say for sure that it is sometimes okay to attack those who dont attack you.
About loyalty. If person isnt loyal to anyone or anything or any cause, person doesnt have any consistent goals in life, making it impossible to guarantee that person is even trustworthy. Such person isnt even loyal to himself, and could betray anyone, even own principles.
So principle of not being loyal to anything is actually self contradicting, because consistent application of any principle requires loyalty to said principle in the first place.
Keeping your word is likewise important. If person doesnt keep word, there is no reason to think person even believes in any principle.
Refusing to harm innocents is likewise important, because if one were to say its okay to harm innocents, everyone could be harmed.
