Two, this isn't any parent. This is Jonathan Kent. He is more than other parents are, just as Superman is more than other men are. Jonathan should be Clark's inspiration to be super, always and unwaveringly. It may be more realistic for a human parent to be uncertain about how absolute to approach the issue of morality, but Jonathan Kent is not just any human parent. He is every bit as special as Clark is. If this scene should turn out to be one that displays moral ambiguity on Jonathan's part, then I think it does the character a disservice.
