Sociopaths feel emotion

I have been surprised by how often I hear or read someone saying that sociopaths don't have emotions or can't form emotional bonds with other people. Most often it's people talking about how sociopaths are soulless monsters or must live lives completely devoid of any real meaningful relationships, but sometimes it's someone saying that he couldn't possibly be a sociopath because he feels emotions and love, etc. This is all fallacy. The three main diagnostic criterions actually have relatively little to say about emotions: Cleckley only mentions "general poverty in major affective reactions" and a poorly integrated sex life, Hare's PCL-R also lists shallow affect, and the DSM-V's ASPD only says that sociopaths tend to experience irritability and don't feel remorse. Nowhere does it say that sociopaths don't love. Nowhere does it say that sociopaths can't form emotional bonds. There is not a single historical example of a sociopath who is a completely emotionless, robot loner, so I don't know from where people are getting this image of the emotionless sociopath.

I thought about this popular misconception when I read this recent comment:

"How does a sociopath know when the missing emotions that make him supposedly so different, since he does not feel them, are feigned? In other words how does he learn to differentiate between feigned and real emotions?"

I am sociopathic, but have some emotion. These emotions are egocentric and only arise with events I am directly involved with, but they are still there. I feel joy and happiness at doing my favorite activities and I can (but may not always) feel anger or sadness when things do not go my way. Nonetheless, these are 'feelings' because they provide information that goes beyond the intellectual analysis of the situation at hand.

Because I have those feelings I can easily contrast those with situations where I do not or am faking them. If I am 'acting' in such a way to not betray myself, and my only contribution to that acting is my intellectual state, then I know that there is an absence of feeling there. If one tells me about how their friend died and they are in tears, I know that I must contribute with an appropriate response so that they 1) do not realize my status and 2) are not feeling any worse. Going through the motions because of this intellectual realization is far different than the automatic response given by most non-sociopaths. I think, by and large, we realize that we are not giving the same response as non-sociopaths because we realize that we have to craft the *entire* interaction with another person, not just the words.

But I don't think even this idea of faking emotions is so different than most people. Do you always mean it when you say "oh, I'm so sorry to hear that"?

Of course who knows whether sociopaths are feeling the same emotions that everyone else is, but I don't think anyone's emotional palette is completely identical to anyone else. Rather people's emotions are going to depend on their culture, their belief system, their education, the societal expectations placed on them, along with the vast natural and physical differences between people's brain and brain chemistry. This applies particularly to a complex emotion like love. I was actually just talking to a friend about how the only reason he can tell his wife loves him is that she very actively ensures that he is sexually satisfied (she's not a sociopath, but this "complaint" could very well be said about many sociopathic spouses). But whatever, right? Who is to say that this is a lesser or less desirable love than someone who would love to hold your hand in a hot air balloon?
