I absolutely want to understand the characters' own moralities first and foremost. There's no point to me in watching or reading fiction if it only serves as a mirror back to confirm my own beliefs or morality. But at the same time, if a character does something that I think is immoral, I'm going to note that action and pay attention to it to see what it tells me about that character. I want to know if the character thinks that what they just did was moral or immoral.
