Like most comic book films, Iron Man has fallen into the classic trap of killing off it's villains. Iron Monger and Whiplash have both met their ends at near the conclusion of their respective films. The Mandarin though is THE Iron Man villain. Would you like to see him killed off at the end of Iron Man 3 if it comes to that? Or have him jailed. Vanish. Escape to survive for a possibly return in another film?
