Generally if their interests and yours incidentally coincide then that's a benefit. I can't imagine all sociopaths just happen to be sexually impressive, though I'd still say that falls into two interests happening to align.
They're also usually charismatic and charming if they've no motivation or there's no benefit to cross you.
I don't think incidental goodness or kindness can really count towards being a "good" person, but I guess that depends if you think strictly motivation or action, with intentional and/or well-meaning or unintentional and/or without any intent are equivalent.
That's a tough question for me. I'm generally utilitarian, which implies action is best, but in evaluation of a person (which includes likely actions in the future), motivation is key.
EDIT: Also, where is the 5% figure coming from? I've always seen 1-2% as the consensus. A psychologist named Hare originally speculated this, and Jon Ronson, who just wrote a book called "The Psychopath Test" repeated that 1-2% statistic on a recent episode of The Daily Show (though he claimed it was significantly higher, close to 25%, in prisons, and around 10% in CEOs and high-ranking business officials).
What I'm saying is that in any relationship, be it sociopath or not, there are benefits which I see as "good", and I can even say there were some good things about my relationships with them. That doesn't mean I think they are good people, overall. I think they are somewhere on the continuum, but many are not nearly as bad as many want to believe, and many don't even indulge as much as a "bad" normal person. It depends on their genes, their families and environments, and how much motivation they have. They are inherently "evil", but just as there are many mostly "good" people who don't do much "good" because they are lazy and unmotivated, you will find the same in the sociopath community. At the end of the day, a guy sitting around, watching tv, and smoking pot isn't currently doing anything "bad", and that's what I mean.......they are not ALL bad. I judge people by their actions, not what is going on in their minds. After all, I could be thinking about killing my boss, but as long as I don't go through with it, it was harmless. They can be good workers who are very thorough in their work; they are good at repetitive tasks. They show up on time, and they do their jobs to-the-letter, everytime. They can and do follow sets of rules and instructions to-the-letter, when they want to. They can do it in exchange for money. So even the motivation there, would not be a "bad" one, only neutral. Just an example.....so therefore, I can't say they are ALL bad, which is what I originally wrote. I think they are anywhere from neutral-to-bad at any point in time, but some of the things they do can be viewed as "good", even though it is a part of an evil web they are creating (such as sending flowers, giving you massages, or wearing the clothes you like to see them in) or even "good" in a more neutral way, such as showing up to work on time everyday. It can be a very close and sensual affair when they are pretending to bond with you. There is nothing in the way of "faking" all-out intimacy. They can generally do above-and-beyond what a normal person can in that situation, and they can morph and fit your definition of a good sexual partner easily and completely. That's what is dangerous about them, is that they have no self, and nothing to be true to. They can easily do what you want, and do it your way. So generally, they can easily be what you are looking for in a sexual partner. The ups-and-downs are tremendous, but if you like intensity, it's a wild ride.
No true sociopath is going to be a legitimate CEO. I guess it COULD happen but it would be extremely, extremely rare. Some people like to think CEO's are "evil" and therefore, a good percentage are sociopaths. Maybe of a used car lot lol..... sociopaths have too many difficulties to make it that far in life. Some of them can be successful as town-lawyers, or teachers, or even physicians, but that's as far as it goes. They can't even make contractions within a sentence unless it is said within a copied phrase. Everything they say must be copied from someone or something else. They can't create their own thoughts. They must go by what they have seen/heard, instructions, and rules. They learn how to act by watching us. A person can fit the diagnosis of a sociopath environmentally but not biologically be, a true sociopath, and that's the only way I could see 10% of REAL CEO's being sociopaths.
I've mostly seen it listed as 5%, but I would think the most credible reference would be the DSM-IV, at this point. "The prevalence of this disorder is 3% in males and 1% from females, as stated from the DSM IV-TR."
No, I don't think ALL sociopaths are good in bed, but it seems to be a trend.
They are generally set-up to be, genetically, and psychologically. Mine wasn't charismatic or charming unless there was a benefit to be had. He was just neutral and quiet. There are many varieties of sociopaths, as there are many varieties of people. The ones I knew (and I have known many, groups of them), will never spend any substantial amount of time in jail. Many of them are musicians in bar-bands and just id-boys, who like to have a hot girlfriend to use and control, and play mindgames with. They're not that violent; only on occasion, and they do little damage then, and the control is not that obvious (they are good at finding ways to get done what they want without being obviously controlling. They can offer many freedoms within a controlling environment). They aren't the stereotypical abusive, controlling types. They just want to smoke their pot and drink, and have sex..... Good? No way, but they aren't Charles Manson either. I was with two for 7 years each, of course at the time, I was none the wiser. I was one messed-up kid lol.... but I made it out with mostly psychological damage, that was apparently already there before I dated them. They just made it worse.
I am in no way advocating dating a sociopath, lol.... I definitely do not see it as a good idea, and much worse could've happened to me than what did. I consider myself lucky that I did not end up in worse conditions. There is slow growth there, and it takes many years to recover from such abuse.
