If you thought that was the point of any of Card's books, then you must not have read them very carefully. The point of Ender's Game was to explore the notion of the ideal human. Ender's shadow also addressed that topic. The adults merely represent forces beyond the protagonists' control, as most adults are in books featuring child characters. The process of character development is one in which the children discover their own nature and the natures of those around them. The reader is intended to ask him/herself which nature is "best" and to thus view a difficult and opaque moral question with the clarity of comparing a group of friends. Quite ingenious, especially when you consider that this is a children's book. I challenge you to find a more insightful novel of ideas with equivalent appeal to the same young demographic.
