It’s simple. For your reader to care about anything you write, you gotta make them. And yes, that goes for the antagonist too.
Take me as your reader for example, the protagonist, I got it..you will make them so likable and have this deep emotional story that I will feel bad for them and root for them. But what about your antagonist? If I can’t understand him/her or why his/her plight is important to them, the book will put me to sleep immediately.
In my books, especially When You Let Go and Anchored By Love I had some female antagonist that my readers still want to hear from. They feel empathy toward them, why? Because I made them care about these characters.
To make a memorable, believable villain, you the writer must make the reader believe in the antagonist twisted sense of reasoning. Show the reader that to the villain(antagonist) their actions make perfect sense to them.
Got questions for me? Drop them in the comments would love the hear from you.
