Goal: To force you to think beyond the bad in your antagonist and consider the good in him, as well as the hurt that contributed to his antagonism. If you have understanding and empathy for your antagonist, you can write an intriguingly deep person who behaves badly but who has or had decency about him at some point.
1. Take a minute to write ten mean things your antagonist did to other people during grade school/childhood. This is very much a brainstorming exercise, forcing you to blurt what you know down deep rather than run things through an editorial filter.
2. Now take a minute writing ten nice things you antagonist did for other people during grade school/childhood.
3. Now spend a minute writing ten ways other people hurt your antagonist during grade school/childhood.
