To discover the architecture for your moral argument, copy the criteria below, then describe how your story works with each criterion. You may find your story does not follow the exact pattern, but you may gain some insight when it deviates and why.  If your story does not follow the criteria, then explain how/why and how this function is achieved in the story. For example, in some stories the attack by the ally may come from inside the hero/heroine, or the opponent may be a natural force, like a tsunami, or just a really cold Maine night.  These are tools for discovery, not templates for fashioning story, so use them that way.
