Extreme Selfishness Leads to Self-Hate

A narcissist loves himself above all others. A narcissist considers his or her own preferences and desires much more important than those of others. Many societies have narcissistic attitudes and established such organized priority of class preferences over those of another class. For instance, a royal family’s preferences have priority as their birth right.
To the narcissist or the selfish, others are considered means to an end. W1 has some limitations (and scarcity exists), usually success in fulfilling one’s preferences would deny others from their preferences.
Achieving pleasure and meanings for one, may cause suffering for others. The feeler become numb to such pleasure and meanings. No longer blinded by euphoria of such achievements, the person sees his own reflection off others' bubbles. The person understands the consequences of one’s actions. Seeing himself as an agent that inflicts pain to others will make him hate himself.
Nevertheless, this process does not happen to every one. There are individuals who have such deep-seated complexes (or indoctrination) that create such strong lenses that always see others as enemy and do not feel no empathy toward others. They see themselves as the chosen race, the chosen tribe, or the chosen species.
