While they don’t commit crimes, they can make life of people around them a living hell with their remorseless attitudes and lack of conscience or emotions.
They can fake emotions to suit their needs and, because of their lack of empathy, never feel sorry for those at the receiving end of their actions. But when the tables are turned, they can be enormously capable of self-pity. It has nothing to do with remorse, but a deep sorow for themselves and for the consequences - to themselves - of what they have done
They will blatantly lie, without blinking an eye, and manipulate others into doing what they want you to do.
