What do you think a character has to have, or show to be considered deep? What is a flat character? I mean, everyone describes its characters, show a little of his background, what he's feeling, etc. How can I recognize if my character is deep enough, captivating enough? My main character is a bad guy. He is evil. Later on, he'll find someone that'll help him change, will make him want to change. Should I worry that nobody will indentify or be captivated by him because he's evil? I appreciate your help.
