Arthur nods thoughtfully. He knows Lancelot is telling the truth as he knows it. There's nobility in the position and Arthur knows that. He's been in the military, he knows a little about moral responsibility, but that's not what drew him to it in the first place. It was just a thing he was mildly aware of as an aside to the structure, the planning and organization.

"I get it. I just feel like sometimes, all of that, the good intentions and everything, it kind of goes out the window when you bring magical oaths and supernatural powers into the mix."

He doesn't mean to dismiss Lancelot, which is why he doesn't say more on the subject, but he can't really admit that he's sure Faolan means to do good. There are too many things at play.
