The satanic person is governed only by the laws of the universe, and does not need to justify themselves to anyone.
On the face of it that makes me sound like I might be a jerk, but it couples undiluted human nature with a love of oneself. My love is pure, and I make sure the people I care about know they're important to me.
There are no underhanded motives, nor forced goodwill through fear of punishment by a God, I am good because it's the right thing to do.
Willful ignorance makes me very angry however, and my hate is also pure.
