Or just start calling him "Raskolnikov" until he figures it out.

If you're not familiar with "Crime and Punishment", the story is about a man named Raskolnikov who thinks he can get away with killing a terrible, old, rich lady who is abusing the good nature of her younger sister. He is not the only one who thinks the world would be a better place without the old lady. So, he attempts the crime but it goes terribly wrong.
