>Geralt insulates himself from what happens in the world. He shows that, to some extent, he doesn’t care what happens to people, as long as he isn’t involved.

Interesting article but I take issue with this paragraph in particular. The "doesn't want to get his hands dirty" angle is overreach. He chooses to take a more humble approach to his own judgment. He knows what is evil and what is not, but to judge between two evils requires more than knowing whether something is wrong or right..a feeling that I think most of us feel "in the pit of our stomach." It requires a belief that one is right about the matter of degrees. The instinct of wrong or right is the feeling he trusts, and the lore is big on communicating that Witchers are highly instinctual. But comparing two evils no longer involves that gut instinct but is instead a heady affair where bias can roam more freely. That he prefers not to choose does not say that he won't if he is forced either.

Lesser or greater evil is a matter for society to decide. He detects evil in a binary, instinctual way and won't pretend otherwise.
