[DC/Marvel/comics] What's the most callous comic book murder?

I've just read the Injustice comic where Sinestro kills a Green Lantern (no spoilers on who) by removing his ring in the middle of space - which seems unnecessary callous. Are there any others like this?

The murder of Green Lantern’s girlfriend Alexandra Dewitt being stuffed into a refrigerator had an impact in both the DC and Marvel universes as villains gradually stopped murdering/raping/depowering the girlfriends of male superheroes for the sole purpose of affecting/motivating them to action. I’m not sure how the Marvel villains learned about her but they got the message just the same.
