Decades ago, there was a time when a certain philosophy spread through society. It was the idea that evil was far more complex than what many would believe, which was propagated through media and entertainment. It tries to contextualize villains by explaining why they are the way they are, as if that would change the nature of what they did.
Circumstances do shape people into who they turn out to be, and some villains had valid reasons for doing what they do. Still, to pretend that evil doesn't exist would be like spitting in the faces of all those who found themselves on the receiving end of its horrors, because no amount of sad backstories could make evil anything other than what it is, and in no context would the killing of hundreds of innocent be morally ambiguous.
