You know, when I was way younger, I really wanted to believe that I was a sociopath (or psychopath - Aman has the right of it, they are both synonymical terms that refer to the same condition. As for Mizal's search result - Aman, Wikipedia is a very accurate source, don't be a douche and certainly don't discount it on the idea that it references Wikipedia alone. However, it is a widely spread, incorrect belief that there is, in fact, a difference between the two.)
I wanted to believe I was one precisely for the reasons you list up there. Intelligent, cold, dangerous, charming - it reads like a Christmas list of awesome personal characteristics.
You look at the movie and tv depictions, or you read the Hannibal* books, and you think "Wow, these guys are awesome", they seemingly operate on an entirely different level than the normal person - and the sad thing is, most people actually seem to think that these depictions are accurate, because of course they don't know what an actual socio/psychopath is like.
Do you know what the sociopathy really is though, Danaos? I'm not talking about the list of characteristics you found on one of the thousands of articles talking about how cool and monstrous sociopaths are, i'm talking about the actual meaning behind the term.
Sociopathy is a mental disability that results in social deficiencies. Hence Sociopathy - Social disease. It's someone who is unable to process emotions correctly, and who is unable to respond correctly to social situations. A common street bum in the middle of an orgy who throws a trash can lid in a homicidal rage after someone walks by him without kneeling before him and shining his dog's shoes is more of a sociopath than Hannibal Lecter or Patrick Bateman will ever be.
Socio/Psychopaths also tend to be portrayed as intelligent - specifically because of their inability to process emotion. They are able to perfectly and logically assess every situation to make the best possible choice, because they are unhindered by such human weaknesses as love, hatred, sorrow or happiness.
Of course, that's because of the common misconception that emotion is a counter to intelligence. It isn't. Emotion is necessary to the decision making process, without it intelligence is irrelevent - you won't ever know what choice to make because you don't feel anything. Without being able to attach importance to something your decisions won't matter. Improperly processing emotions skews your decision making process far more than properly processing them - and regardless, oftentimes what would logically be the best choice is also the wrong one.
Oh, and Aman, House M.D was a great and fairly accurate show, cheap blow, totally uncalled for.
*If you haven't, you totally should, that's an amazing series.
