Bad Emotions Made Good
When writing a story you may find that the good guy has access to a limited range of emotions compared to the bad guy.
Basic emotions (happy, sad, angry, etc.) are easy enough to evoke, but more complex or darker feelings tend to be more difficult to justify.
For example, if the hero’s best friend wins the lottery, a good guy would react how? If he’s a decent human being, probably by being pleased for his friend.
If a friend of the villain—usually a not so wholesome individual—wins the lottery, then the response can be more varied. Pleased (because he plans to ‘share’ in the wealth), jealousy, resentment, maybe even plans to steal the money. These darker thoughts are often more interesting and offer more ideas for where to take a story.
While making your main character evil but still likeable is a very hard thing to achieve, that doesn’t mean you can’t give them (and the reader) the chance to experience the darker side of their personality.
