He may have thought he had no choice, but there were things he could of done..... The comic book Superman could have defeated Zod in that situation without killing him.
Name them or shut up.
At this point you're just a blithering kid who spent a lot of time getting emotionally invested in wanting to hate a movie, look authoritative on something and made a lot of noise about it on the internet. You've ridiculously made allowances for times when he's killed and lived in a world with hundreds of heroes to help and more fantastic tech at his disposal. In the case of Doomsday, it's clear you differentiate the two situations because one looks like a scary, hulking "monster" and one looks like a regular person.
This Superman had neither of those options listed to him available at the time. But you're too invested and entrenched in holding a specific opinion that you made a lot of noise about in front of everyone, and because you can't back down now, you point to inane examples where Superman had more options open to him, yet still killed and say "he had no choice" or "the stakes were higher" even when the "stakes" were exactly the same. You look more and more ridiculous, if that's even possible, every time you reply.
But I need a good fucking laugh, so give the specifics on what these "other options" were. Go ahead. Keep in mind that Zod, having just murdered THOUSANDS of American citizens is subject to American law, and since we executed Bin Laden for less death and destruction, Zod would be found guilty and sentenced to death. And since nothing human made affected Zod, Superman would have to carry out the execution. He doesn't get to escape our laws or punishments.
So let's hear these options that don't result in Superman killing him. I mean, I guess Superman could spend the rest of his days struggling to keep him in a bear hold or something.
"...Superman would have to carry out the execution." What? He would? How exactly would the US government force Superman to do anything of that nature?
As for Super-alternatives to dealing with Zod, he could have used his own heat vision to blast an escape hole in the wall behind the civilians and hold Zod's head a few moments whilst they climbed thru to safety. After they were away, Superman could have lifted Zod up beyond the earth's atmosphere (Supes is, after all, a solar battery and should be considerably more powerful than Zod at this point having lived a life of saturation in the yellow sun of our solar system). I can't remember if MoS Superman needs air to breathe or not so he does one of two things: 1) he gut punches the air out of Zod and waits for him to lose consciousness, or 2) he carries Zod to the dark side of the moon and waits for him to lose his solar-powered mojo enough to knock him out. Either way, it's lights out for Zod and this will give Kal-El an hour or so to burrow out a spider-hole prison to keep Zod incarcerated in, away from the sun and the source of his troublesome powers. With Zod tucked away, now the people of Earth can turn its focus to the complicated and challenging questions of how to deal with an alien that possesses this level of destructive capabilities. And Zod.
This alternative -- obviously -- came off the top of my head but suggests just the tip of the iceberg when it comes to Superman's options at his point in the movie. David Goyer was paid a lot of money and (one would hope) spent a lot of time writing this movie. To paraphrase Mark Waid, Supes killing Zod isn't a failure of the movie's title character; it's a failing in the movie's writer and his lack of a greater imagination. It's not my responsibility or Kirk55555's responsibility to come up with better or more satisfying solutions to Superman's dilemma -- that's why Goyer got the paycheck and not us.
I realize I'm not the "blithering kid" you were calling out but maybe I still gave you that "good fucking laugh" you needed.
