When you’re reading a novel, you notice that the story is told from different points of view. Sometimes you know what characters think, sometimes only one, sometimes many, and sometimes none at all. Often, you get to see the story from both sides, the protagonist’s and the antagonist’s. Sometimes, you only follow the protagonist.
In many stories, knowing what the antagonist thinks is beneficial to the story. It gives you a better understanding of their motivations, and helps you sympathise or hate them.
If you only follow the protagonist, you only know what they think of the antagonist. Your opinion is based on theirs.
I’ve read both kinds of books. I find that depending on the story, they are both appropriate. But do you have a preference? Which do you like to read? Also, if you write, how do you decide whether to show the antagonist’s point of view or not? Let me know in the comments below.
