I’ve been working on my decade-old manuscript, and it’s actually going well. I just have one problem you might be able to help me with.
Several of the characters are part of group, and the group will be disappearing en masse. The fact of the disappearance won’t be shocking because such things have already happened in the story, though it will sadden the two left behind 
and help set up the final act of the story.
I’ve been mostly developing the group roles and trying to present the group itself as a character rather than the individuals in the group because none of them individually advances the story. Consequently, I haven’t done much besides give the individuals brief profile sketches and conflicts within the group, but now I’m wondering if that’s enough.
Since the story is told from a single viewpoint — the main character — any development of other characters has to come from what that one character can observe. A couple of the characters hate the hero and would not tell him anything, so I haven’t given them much of a background, but should I find a way to tell their backstories? Is it necessary?
WRITERS, how fully do you develop your minor characters, especially characters who are going to be killed off?
READERS, how fully do you want to be invested in such characters? Would you feel more cheated if you had to invest time and emotion in such characters only to find out they weren’t pivotal to the story, or would you feel more cheated by not being able to invest emotion in them at all?
