This is my visual representation of evil. If you're Christian, you could call this a depiction of Satan.
Most artists have tended to represent evil as monstrous or seductive, but I for one believe that
the scariest and most effective villains are the ones who don't give off any such ostensible signs of their evilness but instead masquerade as good. They're the people who trick you into sympathizing with their cause and so can accomplish more than villains who flaunt their wickedness for everyone to see. To name only one example, they may be power-hungry politicians who give lip service to ideals like liberty, equality, or law and order. For this reason I decided to represent evil as a cute, chibi-looking purple fairy. Although the purple skin color and lack of facial features was intended to make her ethnically nondescript, I made evil feminine to play with the chivalric stereotype of women as naturally nurturing and innocent (a stereotype which has ironically served to justify patriarchy that kept women in the home with the kids).
I know you dislike anime, but I couldn't help thinking of Kyubey from Puella Magi Madoka Magica when I read the description of this character. Kyubey's whole character revolves around that concept.
