I am currently in the planning stage of a novel-length story. In this story, one of my MC's main motivations is redemption for past deeds. After spending a few hours brainstorming about my characters, I noticed that the main cast had a tendency to represent the different ways people react to and deal with their own pasts/misdeeds/hurts. There are characters that have traits of uncaring indifference, one or two that are cynical and curmudgeonly, one that is angry and (somewhat) violent, one that has given up on people and just carouses all the time, and the MC who is striving to make up for what he has done, plus a few others. My question is, is there any way I can bring out these traits in the character without making it too obvious or chintzy? And can anyone think of a third layer I could add to give the story a bit more depth?
