Arthur shrugs, pausing for a moment to try and figure out what he means to say here. He doesn't want to cause offense, so he speaks evenly and almost hesitantly, hoping Lancelot can see what he's trying to get at. "I think... regular humans have blackmail and persuasion to get other people to do what we want them to. Magic can be far more powerful and binding than either of those things. It's not about supernatural people having a certain character, it's more about the corrupt having better tools at their disposal to get what they want."
