"One aspect of psychopathic bullies is that they home in on Wannabe types - non-psychopathic lesser bullies - and then empower these individuals to gain the positions of power and authority they crave. Once installed, the Wannabe's lack of competence makes them dependent on the chief psychopath, which means they become unwitting but willing compliant puppets. They also make perfect corporate clones and drones. A characteristic of the Wannabe is that as well as lacking all the competencies necessary for their position, they also lack the intellect to understand the nature and manner of their compliant subservience.
Throughout the mobbing experience, the target is deceived into fighting, blaming and trying to hold accountable the minor bullies of the mobbing group rather than the chief bully. The main reason a psychopathic chief bully gets away with his (or her) behaviour repeatedly is that no-one wants to believe that s/he could be the monster s/he is. This is also the reason that many pedophiles and wife-batterers evade accountability and sanction for years, often decades. They appear so charming and plausible to naive, unenlightened and inexperienced people - usually those who haven't experienced bullying themselves. Psychopathic chief bullies are very likely to have everyone in human resources and management in their pocket, who are then manipulated into further mobbing, victimising and persecuting the target.
