Lois is not a disposable Bond girl. In most cases, she is the love of Superman's life. So yeah, if she dies, it's a big deal for him.
No shit. Loved ones dying is a big deal for anyone. That's what makes them loved ones. The problem is when it's used as an exclusive plot device for that person without paying attention to the character of the deceased. Which I'm fine with, as not every character needs to be, strictly speaking, a character rather than a plot device, but this has been disproportionately done to women. If the fact that it's sexist doesn't bother you, then the fact that it's a cliche should. It's boring.
Superman could turn his back on Earth for one other big reason: that it's full of irredeemable sacks of shit like Lex Luthor. If Superman balanced both possibilities; the death of Lois and an unchanging populace, he would still mourn Lois more. Because that's how important Lois and Clark are to each other, not because of some stupid trope thing.
You...don't seem to understand how tropes work. They're components of stories.
Clark and Lois being love interests is a trope.
Lex luthor being a corperate evil scumbag is a trope. They're all tropes. If something works, it's because the writer used tropes correctly, if it doesn't, it's because he used them incorrectly.
Even being tropeless is a trope.
"This didn't happen because of a trope" is not a statement you can give to any story. You can't have a story do something without it being a trope.
You are going in too hard on the sexism angle. I know that Lois has a massive history of sexist portrayals. She had an entire line of comics dedicated to it.
We'll have to wait and see if he'll pulls that particular trigger, but you throwing out alternative explanations does nothing to mitigate the fact that if he does go this route, it will be as problematic, atleast to those who care about how cultural icons inform our society anyway. That's the nature of fridging a female character and I don't feel acknowledging it's existence and that's it's not a good thing is 'going too hard' at all. It's nothing more than describing a thing for what it is.
Also, I don't have to wait for Snyder to fuck this up, BvS
already treats it's female characters like crap. Lois does nothing and has to be rescued in every scene she's in where there's actual danger, making her the perpetual damsel in distress, while Martha is also used as a bargaining chip against Superman by Luthor. The only other women we see are the sex slaves, who are only depicted in their victimized state and some random woman that Bruce is shown sleeping next to. Wonder women excepted, women in this film have a very defined role for the commanding male characters. So given the fact that it's BvS already uses tired, cliche, sexist tropes of women whose purpose in stories revolve around being the objects of rescue by men, I have no reason to believe that Snyder won't also go for this one here too. Now, I'd love to be surprised, but that's unlikely, given the clues being dropped here are about as subtle as a brick to the face. Even if it ends up being something different, I'm still convinced htat the intention here and now is "Lois died, therefore Superman is evil".
