Sociopaths have a gift for saying what you want to hear. They can be smooth and convincing. And before you have a chance to question the veracity of their propaganda, sociopaths will move in for the kill. Sociopaths approach interpersonal relationships as an opportunity to exploit and manipulate. But when they have achieved whatever it was that they wanted from you-be it a sneak peek at your confidential report, a modification of your work schedule, they will discard you like yesterday's Wall Street Journal.
Sociopaths have almost no friends, but many acquaintances.
They will form temporary alliances if it facilitates their opportunistic schemes. However, they will abandon these alliances once there are no further material gains. Former associates can quickly become adversaries in the face of competition. Rather than worrying about morality, the sociopath is primarily concerned about whether his or her scheme will work. The only time sociopaths feel remorse is when they get caught being deceitful, and have to expend the energy to weasel out of the accusations.
