Jürgen Hubert quoted Lucifer by Jeffrey Burton Russell
Evil is an intrinsically fascinating topic. In Lucifer, Jeffrey Burton Russell continues his compelling study …
"...Anselm's first assumption is traditional. Evil is nothing. But he proceeds to analyze this concept rationally. By saying that evil is nothing, he does not mean that the word evil is meaningless, but rather that the concept evil (not good) is identical to the concept nothing (not anything). Such negative concepts have meaning only when referred to a good and a something, as "not John" has meaning only when it refers to John. The word nothing refers only to what it negates. In the same way, the word evil refers only to the good that it negates. Total and complete evil is the same as total and complete nonbeing, the void..."
— Lucifer by Jeffrey Burton Russell (Page 162 - 163)

This book has plenty of historical perspectives on this question - and #ttrpg players who have cosmic forces of Good and Evil in their campaigns could probably learn quite a few useful things from it.
