I read in the Daily Mail quite a while ago that a lot of bosses have psychopathy. The layman's idea of a psychopath is like the villain in that Dirty Harry movie where the bad guy hijacks a busful of school kids. Not actually true, that's the extreme end of the wedge and not at all typical of most psychopaths.
Psychopathy is basically a lack of the ability to empathise and feel pity or be compassionate and caring. It can help contribute to a successful business mind because these bosses are ruthless people. That may or may not be the case here, it sure does sound like it, though. You do get some right hard-bitten, horrible people in management or amongest ambitious people trying to get up there.
I had a boss about 20 years ago who sacked a girl who was pregnant. She went home in the lunch-hour, started bleeding and fainted, she didn't return that afternoon so he sacked her. I'm sure he was a psychopath. He was also a successful, self-made businessman, he had built the business up from nothing. He was also an ex-Royal Marine Commando and had a black belt in full-contact karate. He was the sort of guy who didn't take excuses and he wasn't the nicest person you could meet, but everyone had deep respect for him for his achievements.
