The Dome is built on a foundation of lies (and probably concrete). After all, it was created by Ellery Willux, who lied big-time about the Detonations.
This one lie pretty much overtakes the lives of the Pures; it manipulates them, strips them of power, and even corrupts their minds into thinking the lie is a truth. Partridge attempts to expose this big lie, but that ends up in disaster. This bring us to the central question of Burn: when is it right to tell the truth, and when is it right to lie?

Chew on This
Yes, Willux is evil. But his "fairy tale" is meant to protect the citizens—lying to the Pures was a noble thing to do.
Partridge was a bad ruler because he lied when he shouldn't have, and because he told the truth when he shouldn't have.
