Yes, this! It is so simple. I am always flabbergasted how people feel they need to have always evil things to have conflict in their stories. We don't have those here on Earth, but there hasn't exactly been scarcity of conflict!
I don't know that's what they feel they need.
What I have seen stated is not that they need to have always-evil things to have conflict. It is that they want conflict and its resolution to be simple, unambiguous, and stress-relieving. The real world is complex, and nuanced, so they want to be able to just punch people n the face without worrying about it so much in their entertainment game.
