Here you are clearly fabricating an assumed result to justify your own desired conclusion. I am not saying Superman could have lured Zod away. I am not saying Superman clearly could have saved more lives. I am not assuming any particular result would have happened, based on my own ad hoc psychoanalysis of Superman and/or Zod. Superman could have done a ton of little things. Yes, he could have tried to lure Zod away, or punch him into the air, or, hell, even just looked at a building falling onto some people with a pained expression on his face. Instead, there was absolutely nothing for virtually all of the fighting, especially in Metropolis. I'm not assuming any particular result or reaction, but saying it would have been easy to add something to the Metropolis fighting to show Superman appreciated the wanton death and destruction the fight was causing. The fact that you are resisting even this very, very mild suggestion is utterly mind boggling.
I am not exactly sure how
any of this could have been carried out in a believable fashion with the story that the film presented. Superman is consistently fighting off attempts on his life for every single second he is fighting in Metropolis (and, for that matter, for most of the Smallville fight as well). There is not even a second for him to pause, because the Kryptonians are consistently trying to kill him, and consistently trying to kill
all of humanity as well. I think you're missing the point that Clark
couldn't have lured Zod away or punched him into the air. Zod is a general. Superman has never fought before the events of the film. Zod not only has all of Superman's powers, but he is stronger than Superman and is far better trained. If Superman had tried to lure Zod away or punch him into the air, he would have been unsuccessful, and Zod would just have used that opportunity to slaughter more innocent people,
as he himself explicitly told Clark. Even showing Clark glancing at a falling building with a pained expression on his face would have been unrealistic, because he would be looking away from his attackers, which is not something a person would be likely to do in a fight to the death. The second his attention was distracted could potentially have been fatal.
And, as I have repeatedly mentioned now, Superman
did save the life of the man in the helicopter, so this whole "Superman never showed that he gave a damn about anyone" argument you and Miriel have been repeatedly making is completely unfounded.
It's rather incredible that you of all people (nice personal touch there, btw) are entirely ignoring Occam's Razor, creating justifications that require assumptions about fictional character thoughts and reactions to hypothetical circumstances -- and resisting even the most mild criticisms to the contrary.
Assuming fictional characters are behaving like a predictable human being would behave when put into that circumstance is far from being in violation of Occam's Razor. If anything, it's ignoring Occam's Razor to disregard the tendencies of human behaviour.
Your rationalizations also focus on one or two tiny details, details of which are rather unconvincing when contrasted with the rest of the movie that contradicts the point allegedly being made by them, and you still have not provided any explanation for the lack of death shown in the Metropolis fight -- which, by the way, fits rather neatly into my "they just ignored it as much as possible in favor of big explosions and buildings falling" explanation.
You keep saying the Metropolis fight was whitewashed, but I'm not really sure how much more they could have done to show that the fight was ridiculously destructive and still maintained a PG-13 rating. They already evoked 9/11 about as blatantly as possible, with smoke coming out of the sides of toppling buildings and everything. As I've said, anyone who looks at this film and thinks "There must not have been much loss of life in Metropolis" is clearly not paying attention. They don't need to show buildings actually collapsing on top of living human beings for people to get the idea. People remember what happened in 9/11.
