Is "evil" a thing?

'Indeed recent developments demonstrate that evil remains a stubborn concept in our culture, resistant to attempts to reduce it to pure "physicalism." To read the mainstream media commentary on the Breivik case, for instance, is to come upon, time after time, the word "evil." Not just that the acts were evil, but that he, Breivik was, as a Wall Street Journal columnist put it, "evil incarnate."

But what exactly does that mean? The incarnation of what?'

Evil was, like, so last decade anyway.
