Sociopathology is so common that you really can't avoid either sociopathic or authoritarian personalities.

There may even be sound reasons to keep them around. Most successful leaders, politicians, businessmen are at least borderline sociopaths. Most humans can summon up those traits when needed but are, in normal life, restrained by empathy and conscience.

Outright rejection gets you deeper into the weeds with layers of persiflage and hypocrisy instead of dealing with the issue. The key here is management and monitoring.

You have to understand that the sociopath is always looking out for number one and that conscience and convention are not restraints for them. That everything they do and say will be setup to arrange the situation to their own benefit. Once you understand that their behavior is predictable and it can be harnessed to benefit the larger society.
