The standard cliche' about wuxia is that heroes fight fairly and honorably, but villains often don't. Actually, however, isn't it or shouldn't it be somewhat more complex than that? Are heroes really not allowed to cheat sometimes to defend themselves or save innocents?
Wulin is a dangerous place, full of powerful and unscrupulous people who think nothing of using dishonorable methods to achieve their goals. In light of this, aren't heroes who insist on fighting honorably going to be at a disadvantage in almost all cases? Furthermore, what if the insistence on fighting honorably causes the hero to fail to save innocents that he *could* have saved in only he had been willing to compromise his ethics a bit and resort to cheating?
