Another co-worker jokingly said that so-and-so probably had a spotless apartment with everything always in perfect order, "like a psychopath." Where do people even get these ideas?

From TV shows and movies. Have you noticed how popular crime/killer shows are? I've always wondered why. Fantasy maybe? People enjoy watching characters do things they would never do in their own lives? There's a show that's entirely devoted to sex crimes. A friend told me basically every episode starts out with a murdered prostitute or a case of child abuse. Personally, I don't see the appeal of such a show. Watching the news is rough enough. But apparently lots of people enjoy it! And what about Breaking Bad? I only made it through 1/2 an episode it was so depressing. But it was a huge hit. Dexter was all about a serial killer....a serial killer who only killed "bad guys"....that concept made me chuckle. House of Cards was basically about a couple of psychopaths.
