Because they play dirty. They don’t follow any rules of civil interaction. Lacking a conscience, they have no moral constraints on their behavior, and when confronted, they simply deny their evil deeds. They couldn’t care less about civility, decency, morality, or honor as long as their actions pay out and their unethical behavior is kept under the public radar. They are free to lie, con, deceive, manipulate, intimidate, incriminate, or use any other trick in the book.
We may not recognize the disingenuous conniving techniques they use to control and manipulate. An experienced abuser is extraordinarily devious and almost impossible to pin down. Primed with denial strategies, he’s always ahead of the game.
Psychopaths use numerous deception tactics to create and maintain a respectable, virtuous, likable—maybe even admirable—public persona that deceives the best of us. They take advantage of our tendency to not recognize evidence that contradicts our beliefs, such as dishonesty and other lowly character traits in an individual who has ‘won’ our trust, respect, and appreciation. The persona provides a cover for devious schemes, exploitation, and abuse.
A psychopathic individual may believe that all of us play the same game—only he is smarter and superior while most other people are weak and inferior pushovers. Until understanding of psychopathy becomes widespread public knowledge, the predator’s hunting grounds will remain saturated with easy prey.
