Unless I am missing some HW information (I haven't played the expansion yet), that Au Ra are half demon is only mere speculation, not unlike the theories (so far disproven wrong) that they are half dragon or reptilian in any way. It'd be like implying that Miqo'te are part coeurl, no?
To be an interesting, intriguing, well-written character, there needs to be something to allow the audience to relate to them. That is what the problem is with who wants their character to be "perfect". Perfect characters will never be strong, and strong characters will never be perfect, because WE (those who read, who watch, who RP) are not perfect.
