Some of the most popular movies and TV shows feature likeable killers, and the sympathetic monster is a common character in great fiction. (Think Frankenstein’s monster.) There’s a theory that reading fiction helps us learn to understand other people — so does reading about fictional monsters help us feel empathy for real-life criminals? Joshua Landy is a professor of French and Comparative Literature at Stanford and he says fiction can help us be kinder and more empathetic. But it doesn’t necessarily make us better people.
