“He is with me wherever I go,” said Quirrell quietly. “I met him when I traveled around the world. A foolish young man I was then, full of ridiculous ideas about good and evil. Lord Voldemort showed me how wrong I was. There is no good and evil, there is only power, and those too weak to seek it… Since then, I have served him faithfully, although I have let him down many times.

Do you see the gaping hole in Voldemort’s world view? There is no good or evil, he says and teaches his protege’, yet he is harsh and unforgiving when let down. But what is the let down if not evil to Voldemort? There is not such thing as a practical universalist. If a person tells you they don’t believe in good or evil, go and let the air out of their car tire or trick them into giving you their pay check, then you’ll see they believe in evil. No matter what we do all of us smuggle into our minds some standard against which we measure the world. It is unavoidable. It is the result of a created world, not a random one.
