Yeah I'm not sure if he is either. I haven't seen Aladdin in the longest time though so I can't say. Ne-ENXp at the least from what I remember, probably sp and E7.
I never read the book, but in the film he has the same sort of air that other (male) Disney ENFj villians have. There's that sort of well-spoken smoothness to the way he speaks that Scar and Maleficent share (assuming I remember Maleficent correctly).
It's a pretty delta movie as far as I'm concerned. Roger and Anita could be some sort of ESTj/INFj pairing too.
