Arthur actually stops, and looks towards the sound of Bucky's voice with an expression of - it would be generous not to call it disgust, but that's more of the undertone to the disbelief and indignation that are much more surface level.

"Bucky, these people live under constant surveillance," he says, his tone once more explanatory but this time imploring him to examine why this is a Bad Thing. "If what we experience ourselves is any indication, these people also face the same threats we do, that if they don't perform to the demand this place expects of them that they too will get tortured into compliance. This threat of- war, of immanent destruction is being used to inspire fear, to cause horrible damage to the reputation of anyone who acts differently, to encourage the notion that reporting these people is the best option, that being complicit in their fucking torture makes you a good person."

The venom is back in his tone despite himself as the bullshit of this place gets to him. "The only reason this place is nice is because it's built on the bones of terror, on obedience on pain of death or worse. And we are trapped here at the whims of this fucking cult unless and until we can find some way to either undermine it or destroy it."
