Would a story be taken seriously if there is only a slight change in the MC, before reverting back to their original behavior, at the end? Do all of your MCs shift perspectives in all of your stories? I know, ideally, you're supposed to make that happen, but, do you? Do you have another approach? And finally, Is it more interesting to have a protagonist change from bad to good or good to bad, for lack of a better term. This probably isn't too clear but it's something I've been thinking about for a few days.
