Werewolves and vampires seem a funny thing to me, in a certain sense. That is, once someone becomes, or is to cursed to be, such a monster, they are no longer human. Which is all well and good, but at the same time, both monsters can be very human at times - say, the werewolf when the moon isn't all a'shine, and the vampire with the fangs retracted. So - what keeps them from being labeled as a human that's been stricken with a curse; why the default inhuman label? Would it be too much to say that a human has the potential within their humanity to become a monster? Is it easier to just say they are a monster and strip them of any (good or bad) humanity - couldn't a normal human become just as animalistic or depraved without any external (internal?) influence (a la the end of 28 Days Later, for example)?
      Also, from another side of things, what about the Amerindian idea of a shapeshifter? That, I know very little about, unfortunately, but would anyone be able to tell me whether they are considered primarily human or inhuman?
