No. "Sociopath" is not a pejorative term for a guy who is successful with women. The hallmark of a sociopath is that they have no conscience:

In the eyes of girls the worst "crime" a man can commit is to be
emotionally needy; to be insecure, to need the girls to validate him. A sociopath is the opposite of that: a man who is, deep down, completely unmoved by, and indifferent to, their opinion of him. At the same time he seems very attentive and charming on the surface, they can sense he is ultimately remote, just doesn't care.
At first they're delighted by this refreshing, non-needy man who is so lavish with attention, but then something starts to bother them: a deep itch to break through his inner indifference, to be taken seriously. This itch escalates to something obsessive: the need to get
his validation. But the more they try to impress him, to please him, the more amused he looks, and the less seriously he seems to take them inside.
Once the sociopath senses the hook is set, he'll start casting himself as the hapless victim of circumstances beyond his control needing a bailout (money, goods, shelter, or whatever he happens to want) and he'll keep that up as long as he can get away with it, thoroughly reveling in the fact he's got someone under his thumb. No sympathy, empathy, or remorse involved.
There’s the kernel of a lesson for nerds in the story of the girl’s attraction to the sociopath, which could be stated many ways, but here’s one: girls are attracted to guys who are warm and attentive on the surface but who give off the unspoken vibe they feel utterly neutral toward the girl. Why? The guy’s not needy, doesn’t need to be validated. By the same logic the guy who
believes he is God’s Gift to women is attractive for the same reason: not needy.
