Every person wants to be seen as important or unique. But, narcissistic sociopaths believe themselves to be entitled to special treatment and see themselves as above the laws and niceties of normal society. They sometimes seek to prop up this attitude through “accomplishment;” scratching for positions of power and influence in order to reinforce the notion that they are special compared to others.
Of course, power is usually an artificial construct because the only power we have over others is the power they give us, knowingly or unknowingly. Power does not make one special. The narcissistic sociopath does not make such distinctions, however. He/she only distinguishes between the people who strive for dominance and everyone else. In their minds, people that covet power are a superior subspecies, while people who do not covet power are considered bugs.
