In the Hindu mythology there is the concept of Kali, or the ultimate suffering and pain. Rather than being evil, Kali is worshiped because without her (or at least the _idea_ of her) we could not truly experience happiness. This is based on a (religious) psychological idea that to enjoy anything you must have the really terrible awfulness there in the back of your mind, as something that could spring out from the corners. Something like that anyway. Horror films and dark stories make everyday life feel more enjoyable. Or they could, if we can take things in that light.
