From a reader:
I'm not sure exactly how interested you are in anime, but I thought I'd recommend Puella Magi Madoka Magica. It's a 12 episode anime which at first, due to the title and opening song, appears very much like some terrible fantasy anime made for eight year old girls, but probably by episode two you'll start to see why I would recommend it to you. The show is basically about how an alien creature named Kyubey, promises to grant one wish to teenage girls in exchange that they fight witches. Throughout the series you'll learn his real motivation, and what sort of emotionless, selfish lives these girls must learn to lead in order to protect themselves. Yet throughout all the times they're suffering, he's just smiling and cute and completely unaffected. Where he comes from, emotion is a mental disorder.
Also looking this up, I came across the concept that Daleks are sociopaths. Ahaha maybe.
