Lack of empathy

The narcissistic pervert are unable to love others. The vast majority, they have no "humanity", no human feeling, no qualms, no affect. They are cold and calculeurs, totally indifferent to the suffering of others. But while, in most cases, incapable of human feelings, they simulate being completely filled, apparently, good human emotions and a sincere empathy for others. The evil can be passionate about a person, business or idea, but these outbreaks are very superficial. They are often empty of interest, except for their immediate interest. They ignore the real feelings, especially feelings of sadness or grief (for others). The disappointments cause either of anger or resentment with a desire for revenge. This explains the destructive rage that seizes them when separations. When one sees a perverse narcissistic wound (defeat, rejection), he feels an unlimited desire to get revenge. It's not as angry in an individual, a transient response and messy, it's a grudge inflexible, implacable when the evil uses all his strength and his reasoning skills. And now it will only cease to indulge his plan of revenge. Perverse seduction has no affect, because the very principle of operation is to avoid any adverse affect. The perverse, as the paranoid, keep an emotional distance sufficient to engage never really. The effectiveness of their attacks is that the victim or the outside observer can not imagine anyone could be so devoid of concern or compassion for the suffering of others. Any sexual dysfunctions or "evil" land could be the consequences of this lack of feeling and empathy for others. It is possible that the lack of affect prevents feel the full moral boundaries between what is permitted or prohibited in society. But this is only a hypothesis.
