Took me a minute to catch that by "medievalists" you meant people living in the middle ages and not its contemporary meaning of people who study the middle ages. Anyway though I don't think it's true even adjusting for that. Good vs evil is a model of causes, but not mechanism. Even if you orient in terms of it (which people still do!) you must identify causes and act on them, which also middle ages people did.
