“You seem to think that the only genuine existence evil can have is conscious existence - that no one is evil unless he admits it to himself. I disagree.”

“The proposition has… been laid down in the most general terms, "All evils are negations." Thus for man death is evil; death is his non-existence. Illness, poverty, and ignorance are evils for man; all these are privations of properties…. The destruction of other things is likewise nothing but the absence of their form. After these propositions, it must be admitted as a fact that it cannot be said of God that He directly creates evil, or He has the direct intention to produce evil; this is impossible. His works are all perfectly good. He only produces existence, and all existence is good; whilst evils are of a negative character, and cannot be acted upon.”

“Only Evil and Greater Evil exist and beyond them, in the shadows, lurks True Evil. True Evil, Geralt, is something you can barely imagine, even if you believe nothing can still surprise you. And sometimes True Evil seizes you by the throat and demands that you choose between it and another, slightly lesser, Evil.”

“The so-called evils are evils only in relation to a certain thing, and that which is evil in relation to a certain existing thing, either includes the non-existence of that thing or the non-existence of some of its good conditions.”

“Everything is evil. I mean, everything that is, is wicked; every existing thing is an evil; everything exists for a wicked end. Existence is a wickedness and is ordained for wickedness. Evil is the end, the final purpose, of the universe…The only good is nonbeing; the only really good thing is the thing that is not, things that are not things; all things are bad.”

“There is an idea of free will associated with it too. In order for there to be being, there has to be limitation. In order for there to be good, there has to be the possibility of evil. I think the right path is to exist such that the possibility of evil remains open, but that you choose the good. And I don't think that evil perse is built into the structure of the world. But I do think that it's human. I think that evil is human. And I think it's understandable. There is a difference between evil and tragedy. Tragedy does seem to be built into the structure of the world. But human beings seem to be equipped to deal with tragedy, but we are not equipped to deal with malevolence. That destroys people. I think that, metaphysically thinking, the world is structured such that humans have a choice between good and evil. Why do we have a choice? We don't know.”

“Hysterical optimism will prevail until the world again admits the existence of tragedy, and it cannot admit the existence of tragedy until it again distinguishes between good and evil… Hysterical optimism as a sin against knowledge.”

“It is not the misuse of power that is evil; the very existence of power is an evil.”

“The only reason that evil exist is to challenge the good among us to defeated it.”

“Believe me, no one is completely good. Similarly, no one is completely evil. It depends on where you stand, and how you look at it. Protagonists and antagonists only exist in fiction.”
