@Genocider:
I doubt it. Sinbad's dark half was caused by a curse rather than him taking in the magoi of someone else. And IRC Kassim's magoi seemed to have been purified back when Aladdin thanked him for protecting Alibaba from the curse that almost killed him.
I thought the curse wasn't really effective aginst Sinbad was because he was already half fallen, maybe I misunderstood it. I believe your right about Kassim magoi, since the two magoi were conflicting I assumed one was positive and the negitive. The second episode was pretty good, more changes from the manga but none were bad in my opinion(really pushing the flame theme for Amon).
