Point. I wouldn't use the word "sociopath" there, but it's possible to be low in empathy and still not a bad person.
That's actually a skill in the corporate environment because snooty clubs (like an executive suite) generally look for non-stickiness, i.e. "you get just me". People who communicate, "I'll leave my friends at the bottom unless you ask for them", tend to get promoted faster than those who are seen as a risk of bringing in less-wanted friends.
