the movie I saw needed a guy who was a highly intelligent, super strong product of "selective breeding". Khan would seem to fit that bill.
I don't think there was anything in the movie at all about selective breeding. In fact, there was next to nothing about Khan's past or motivations. We know that the movie was originally written as not Khan, and Lindelof wanted it to be Khan so they tailored the role for him. It could have been anybody really because the role was so generic. He could have been a green-skinned alien and it wouldn't have made much of a difference.
