I spent a lot of time thinking over this one, and haven't finished by any way.
But thoughts so far are these:
Are you bound by the codes of other people?
Isn't is important to consider that value of other people's codes of honour before you make them yours?
Isn't it honourable to fight them, if they seem wrong?
Shouldn't codes of honour have a reason? Some idea of right or wrong? Or are they just identity markers and identity creators?
Where do 'ethics' come into it?
