Re: How Superman Resolved the Issue of Zod *MEGA SPOILER*
I'm sorry, but this whole "Superman doesn't kill...period" business is stupid. In the comics, this is one thing. But in film, that just can't be. Deep down to the core, a superhero not killing a villain in the comics isn't truly because the writer believes the character is morally just. It is a plot device in order to keep villains around for a future story. Don't get it twisted. The latter is the true reason why many superheroes don't kill members of their rogues gallery.
With that said, I will reiterate. This is a film. This film showcases Superman in a world that we can view as a parallel to ours as well as tangible. In the comics, Superman is idealistic about not using lethal force against his enemies because he has powers that members of the human race lack. However, he isn't blindly devoted to or not impossibly inflexible to that rule. Superman knows that an exception will always exist.
In conclusion, comic books aren't reality. This is a film. Two completely different mediums. Many things that work in the comics don't work in film. Adaptation does not allow for a seamless transition. Across mediums, something being changed is necessary.
