Actually, Morgana...I think she's home but the lights of her soul are out.
Like all of us, I have seen the face of great evil. Miley has no power but that to persuade some children to turn to the dark side...but her face indicates that she is now devoid of conscience and absolutely full of evil.
I went back and looked at the picture and you are right. She really does look demonic. I am not sure she really is but she has that look.
