I agree with the lack of empathy and compassion, but Jung made a statement that the brighter the light the darker the shadow. He also said if we don't own our own shadow it makes it easy for the devil to slip in the back door metaphysically speaking. There is a new film and book out entitled The Shadow Effect that you can check out at this website

I read the book but haven't seen the film. If you click on where it says The Event at the bottom you can listen to an hour and a half long interview with the 3 authors.
Robert A Johnson wrote a great little book also entitled Owning Your Own Shadow.
M. Scott Peck wrote an interesting book also concerning evil entitled People of the Lie if anyone is interested.
