Workplace psychopaths can't be stopped or cured.
“They wouldn’t recognise themselves as a psychopath but the behaviour is always conscious and intentional,” Dr John Clarke says.

“Some of the ones I’ve spoken to don’t really see why it’s such a big issue because they see it more as a strategy they need to use to survive. It’s survival of the fittest.”

Workplace psychopaths consider themselves to be smarter than everyone else.

They inflict psychological harm upon colleagues deliberately.

When the victim publicly suffers, the psychopath derives enjoyment from seeing evidence they’re able to hurt and conquer another person.

Dr Clarke adds: “There’s an absolute lack of conscience, lack of remorse, and lack of guilt. They’re manipulative, superficially charming, and pathological liars. They like conning people and there’s a grandiose sense of self-importance.”

Their key tactic is to win the important people over first.

“People actually like them,” he says. “They use their excellent verbal abilities to create this false persona and people find them exciting, dynamic and engaging, and they use that to camouflage the torture they’re inflicting on their co-workers.”

Rehabilitation makes psychopaths worse.

Rehabilitation programs teach them better social skills, and the psychopath then uses those better social skills to target victims more effectively.

“The ultimate form of power and control is to destroy people, and that’s the motivation for their behaviours, and that’s why it’ll never change,” says Dr Clarke.

They see no need to change their behaviour because society rewards them for it.

They get promotions, more money and even awards for what they do.
