@Walter Hinteler,
He has no internal mechanism that we'd describe as "a conscience". He will lie (and he does lie daily, often multiple times a day) to anyone and to everyone without any sign at all of remorse, guillt or regret. He clearly does not care who he hurts or how many he hurts or how badly he hurts them. Everything is about greed, domination and self-aggrandizement.
He
is a sociopath.
Quote:The DSM-5 states that the essential feature is their willingness to “disregard [or violate] the rights of others.” From my experience of over 30 years dealing with legal cases, family conflicts, workplace disputes and other situations as a high-conflict consultant, I would say that the driving force with sociopaths (and they have lots of energy) is to dominate others. This may or may not involve breaking the law. They want to dominate people in order to get things from them, such as their possessions, money, sex, business partners, homes, cars, investments, reputation and so forth. But they also like dominating others just for the feeling of it—the feeling of power and control. Sociopaths lack a conscience, so they will do anything to get what they want.
...Sociopaths are fast talkers. Their words are mostly false, if not entirely false. But they use many, many words designed to cover their behavior. They may be a completely different person from who they say that they are. Watch out for extremes. Big promises. Big stories, about the past or the future. Big plans, with no basis for them or no experience at whatever they’re planning.
There's much more at this
Psychology Today article and much, much more you can go through via wikipedia. But it is long past time that we all got honest about what this guy is and the danger this situation presents.
