Whenever people talk about villains, characters who are under the influence of an evil force such as Lyon, Julius, Hardin are talked about. But if they're being mind controlled, possessed or brainwashed, than that is no longer them. A villain is someone who is contemptible but a possessed person is not deserving of scorn because they have no agency when they do their actions. That's like saying Celica was a villain when she fought Alm but no one calls Celica at that point in time a villain because she was possessed and had no free will. So why is Celica, in that moment, not considered a villain but characters like Julius are even though Celica is more responsible for getting possessed than Julius who just happened to touch some book and had no idea what he was getting into?
