Are all Narcissists also Sociopaths?

I am sorry if I did not notice this had been posted before, it did not come to my attention.. The original post was 39 weeks ago and I did not have recollection of it. Clearly this is a topic that is still of interest. If we have had this discussion before, does that mean there is not anything to add to it and it should be considered a closed matter and not put forward again? Perhaps there are new members of the forum who did not see the original discussion, or have something new to add to it. I am asking, so I will know in the future, not to post anything that is related to anything posted before. I did go on to read the links you attached to your post, and do not agree with your statement that it goes only one way.. Specifically the statement "All Socio/Psychopaths are Narcissists" The reason I disagree with this statement comes from Steve Becker's article that you attached which attempts to distinguish the two, specifically: "The less validating you are, the less worth you have for the narcissist. The less exploitable you are, the less worth you have for the sociopath." There are many traits that narcissists and sociopaths have in common which is why in some cases it is difficult to make a distinction. There is one key difference-- narcissists require their victims to validate them, and sociopaths are often in it only to exploit their victims (for the game). Neither narcissists or sociopaths feel empathy for others, but narcissists feel their own pain (and emptiness) deeply, whereas sociopaths feel nothing. When you stated that all sociopaths are narcissists you implied that they need the same supply-driven validation and this is not true. They only require that their victim is available for exploitation. This is not the same as NS (narcissistic supply) I would think the reverse statement "narcissists are sociopaths" is closer to the truth--- it would be impossible to use a victim for constant supply-validation, without (either directly or indirectly) exploiting them at he same time. Sorry for the ramble (sigh....!), but I felt this was an interesting and relevant subject.
