I am rather intrigued by the idea of the evil twin, where all of us, somewhere on earth, have a twin self that is as malignant and morally corrupt as we ourselves are innocent and pure. Or just the opposite, if you like.

And of course, the opposite would have to be true, because if each of us has an evil twin, then each evil twin must have their own evil twin, aka the virtuous twin. That would be us, right?
