Yes.That's just the way stories work.
But, there is a difference between what we as readers/viewers care about than what other characters on page/screen care about.
Most of us would be background characters in the sort of comics we read. (No powers? No real connections to the corridors of power? Didn't think so.)
But, as a civilized man, I would want the perpetrators of mass violence cages/killed. I do want them caged/killed.
Atlantis is a hostile state. Atlanteans are bad guys. If they are not bad guys, they are still adversaries, and the Avengers should have turned Namor in to fishsticks any number of times.
The problem is even more blatant in various X-Men comics. Just about every monster the team deals with ends up getting invited over for Sunday dinner, or at least a summer BBQ. And, that makes the X-Men reprehensible.
There is nothing wrong with reprehensible characters. It can work, very well. But, in the case of the X-Men, or Marvel at large, it is not always clear if the writers know that the characters are behaving reprehensibly.
The idea that the Hulk has never killed anybody is one of the most idiotic things in comics. The Avengers probably should have slit the Scarlett Witch's throat well before "House of M". (At the very least, they should have tried.) She is a super-powered lunatic.
Showing the Avengers (or whatever team) as demonstrably unconcerned with the real damage that their battles cause justifies the sophomoric idiocy of Garth Ennis' "the Boys". Garth Ennis does not pitch high. But, he knows that his characters are depraved, which is more than can be said for most comic writers.
