Of course, but that's a rather simplistic view. Why shouldn't a deformed body be able to give the appearance of a human with the help of magic? Magic controlled by a being controlling that magic?
In fact, in the Guild Wars universe, all things are made of mist, and the soul of a being is made of mist, without mist there would be no living being. Mist is the fabric of reality.
But it's just an idea, at the moment we don't know much about who the Kryptis are, apart from a race of demons from the Mists ^^ I just thought it would be cool if humans and human gods had a link with them, which would explain a lot.
