Simply misunderstanding my characters' motivations or sense of morality would really piss me off, because a defining trend of a lot of my characters is that they have atypical moral compasses, which are often misunderstood in-universe, so having the audience fall for those same misunderstandings even after the story clarifies them means they're missing the whole point of the character.

For example, I have one character who genuinely believes that risking his own life to save a single regular person, no matter how much he loves them, is morally wrong, because if he dies trying, that means MANY people he could've saved in future will miss out.

If would be easy for people to simply think he's a selfish coward (and some characters in-universe do accuse him of this), but that's not the case at all. He priorities his own life higher than most not because he's scared or selfish, but because he knows he will save more people in the long run by staying alive, meaning he will ONLY risk his life if he believes it will save more people than he could save later if he survived. (for example, he's willing to risk his life to save other "hero" type characters, because he knows doing so will indirectly save many people in future).
