Another excellent wakeup call from Les. From the page:
There is an alien race among us and they are scary powerful. They are not scary powerful because they are that much smarter than the rest of us. They are so because there are no moral constraints upon their behavior. They do not have the self-limiter of conscience. They are without conscience altogether. They are psychopaths. No doubt you have asked yourself how certain men and women could do the things they have done; how could they kill and torment millions of people with no regret whatsoever? Study a bit about Ponerology and you will not have to ask this question again.
