The Order of the Hawk absolutely had teeth - but only when Jenred was around. He was its teeth.
As soon as Jenred disappeared from the picture the Order of the Hawk disappeared from sight - because no one was committed enough to its principles to ensure they carried on being enforced. So all I'm saying is that those nobles (including current emperors) who were around back then yet complain about "dishonourable" behaviour by other realms weren't very good at putting their money where their mouth was when it came to the best tool FEI had for ensuring that honourable behaviour was followed.
I don't think that's the case, at least when it comes to looting. Rape/killing has long been banned as a method of looting in Arcaea, and more than one noble has been punished and even banned for disobeying this. In additon, it is a specific term in the treaty all Empire realms have signed to abide by such looting restrictions as well.
