I think it's very hard to watch MoS and view Clark as someone who values life in the way even the average person does, to say nothing of one of the paragons of goodness in fiction.Nothing from MoS tells me Clark didn't understand murder was bad. That might not be what you're saying, but if it is, its a serious misread of the movie IMO.
When we watched it in theaters, my son, who was then in elementary school, turned to me and asked why Superman was letting Smallville get destroyed. It would have been trivial to have spared Smallville and even Metropolis much of the damage they suffered. By the end of the movie, Metropolis has suffered damage comparable to a nuclear weapon being dropped there, minus the radioactivity.
Snyder's version of Superman simply doesn't even have the moral compass that the average child does.
