I think we are becoming desensitized to deaths in our media. Creators have to go the extra mile to make a death meaningful nowadays. Just a few decades ago, if someone died in a story, the audience/reader would be shocked. “I can’t believe they died. What’s going to happen next?” And that happened even for bit characters (read: not mooks, but not stars either).
In our modern media, it’s come to the point where Superman has to destroy an entire city before we’re shocked.
On another note, our modern media’s dark tones and themes means that when the Avengers put the lives of an entire city over the goal of defeating the bad guy, we are equally shocked.
Maybe there’s a middle ground here somewhere.
