Back to the issue of Krypton's destruction and Zod's motivations - based on the new Empire article, does anyone wonder if Jor-El's ethics or plans for Earth are not as different from Zod's as we may think. It was mentioned that Jor-El's motives for sending Kal-El to Earth are not as noble as we might think and that propagation of the species has a strong bearing on his decision. A good number of people here have complained about the possible destiny/messiah angle being retreaded in Man of Steel based on Jor-El's speech about Kal-El and the people of Earth. I wonder if Man of Steel might portray that attitude of superiority in a negative or at least morally dubious light given the hints about Jor-El's motives. That Jor-El, despite his comparative wisdom to the rest of Krypton, is equally superior and thinks that Kal-El ought to lead Earth to become a New Krypton, a better one. What if Jor-El's well-meaning but patronizing attitude towards the people of Earth is partially rejected by Clark.
I think perhaps Clark becomes Superman by balancing Jor-El's confidence/arrogance and Pa Kent's fear/humility. Clark refuses to impose himself on Earth as a god or leader as Jor-El would have wanted, but he also refuses to hide in the shadows like Pa Kent might have preferred. Rather, instead of accepting either father's distrustful opinion of humanity (Jor-El distrusting their ability to advance on their own and Jonathan distrusting their ability to accept that what is different), perhaps Clark is alone in accepting an optimistic opinion of humanity. Perhaps his travels have taught him about the innate goodness of human beings although it takes Clark a while to realize it.
