1. Begin with the psychological weakness. 2. Figure out what kind of immoral action might naturally come out of that. 3. Identify the deep-seated moral weakness and need that are the source of this action. A second technique for creating a good moral need is to push a strength so far that it becomes a weakness. The technique works like this: 1. Identify a virtue in your character. Then make him so passionate about it that it becomes oppressive. 2. Come up with a value the character believes in. Then find the negative version of that value.
