Psychopath vs. High-Functioning Sociopath

╟ So·ci·o·path ╢
╔
Noun
A person with a personality disorder manifesting itself in extreme antisocial attitudes and behavior and lack of conscience.
╝
In other words, severe form of lack of empathy and lack of guilt which is why they are often compared to psychopaths. However not to get the two confused with each other, sociopaths often blend in well with society because they are able to form deep bonds with others, where psychopaths cannot.
It is also said that sociopaths can brainwash anyone into doing what they say, and can even brainwash people to love them.

Sherlock Holmes was a high-functioning sociopath.

And she was in love brainwashed by him.
Completely and Utterly brainwashed by him.

But how can a psychopath with no emotion be brainwashed by a sociopath with very little emotion?
