As a fiction writer, my main job is to make up stuff and write about things that I’ve never experienced (and probably never will, since I write fantasy and sci-fi). And sometimes, in the course of writing about people, places, and events that I’ve never seen or experienced, something comes along that directly violates my personal principles and beliefs. 

So what do you do, as a writer, if, for the sake of the story, you need to write about something that is the very antithesis of who you are as a person? I’m sure plenty of mystery and thriller writers have asked themselves this question. After all, the vast majority of people who write murder mysteries are not, in fact, murderers.
