Actually, one of these days I need to finish Civil War II just to see what horrible thing Carol did. One of my main issues with that run, at least with the first 4 or 5-ish issues, was that I was supposed to see what argument from both sides or something, but it was clear Carol was correct.
So you find this kid who can see possible realities if you don't intervene, which allows you to save the world once, and then he sees Thanos will come and fuck shit up, so you make a plan to stop him, and while doing that someone dies and another is hurt badly and I'm supposed to think this was an issue for some reason? If you didn't stop him then, everyone would've died, and soldiers get hurt while doing soldier shit.
I dunno, maybe they make her lose her mind later on in the event or something, but those first issues and just thinking "why the hell should I be listening to Tony Stark right now?".
