I had a friend who was a sociopath... learning about sociopathy in general was one of the most fascinating experiences. This person was incredibly perceptive, with a piercing intellect and spontaneous creativity, and seemed to excel at all he turned his hand to. However, life was ultimately unfulfilling for him because he felt so surrounded by idiots and imbeciles, and was himself so free of emotional inhibitions that he knew he could do more or less whatever he wanted. I always appreciated his complete and utter disdain for social norms, and the ways we would become each other's mutual psych experiment, even if it was difficult to learn that not one iota of his interest in me was emotional in nature. Sociopaths may be bereft of the empathic emotionality that constitutes the core of the neurotypical human experience, but I also feel there is much in the plight of the sociopath that is mirrored in 'normal' people, too; in essence, it is like gazing into a looking glass, seeing our basest, most ugly and unrestrained desires staring us back in our faces.
However, I feel so deeply sorry for people who had been in intimate relationships with these people. Honestly, I harbour no malice towards the sociopaths because they don't operate on the same emotional paradigm of most of humanity. Their actions are not 'evil' insofar as they are not malicious in intention, merely selfish, as they cannot be anything else. However, there is even an inherent selfishness to the most deeply emotional and sentimental of people - that we are not lied to, that we are never deceived or manipulated, that our feelings are viscerally understood and reciprocated. The sociopath, by nature of their very being, is unable to fulfil this requirement. I have no doubt that they do 'love' in their way, but never the twain shall meet. My heart goes out to everyone who has been unwittingly hurt by these people. Ultimately, I can't say that I hate them, as in many cases they are fascinating, beguiling and seductive existences, however I am quite content to watch that brilliant, chaotic maelström from a safe distance, never becoming swept up in its immediate vicinity.
