"You go around thinking that it's not fair that the wretches have to live out there. But I know that it's not fair that the Pures have to live in here—behind glass, battling around in our little fake world. If the Dome fell, it would be a mercy—not for the wretches, but the Pures." (55.8)
The Pures suffer just as much as the wretches—that's the truth. The Pures can't understand the wretches' suffering because they've dehumanized them, but the wretches can't understand the Pures' suffering because they've put them on a pedestal. The truth is hidden from both sides.
