Yes these people rise up through organisations, and can end up in positions where they can do a great deal of harm due to the power they accrue ( introduce policies that lose people their jobs/health/lives? start wars? )

Sad but true - there is indeed a lot of evidence to suggest that a lot of our leaders in business and politics do have personality disorder tendencies, usually of the sociopathic kind. This is because they have a collection of abilities that make for success going up the slippery pole-

- The ability to read other people very accurately and use that info to their advantage because the do not care about the consequences to others
- well developed skills in deception and manipulation
- a massively resilient ego and sense of self importance which is impervious to appeals to moral imperatives such as respect for others, shared responsibility for those unable to care for themselves, the greatest good for the greatest number etc


O god I am really depressed now....
