Quote #4
He's taken away their lie—the one that allowed them to function in the world around them. If you rob them of their lie, they'll self-destruct. (6.2)

Quote #5
And Partridge has uncovered so many secrets—destruction, death, and so many layers of lies. He doesn't want to know any more of them. (6.97)
Partridge can't handle the lies he's been fed at this point—now, he feels like he's living a lie.
Quote #6
"No. Brave is what I'm doing now. Brave is ending the lie," he says, and an awful smile cracks at the edge of his mouth. "I've been a coward up until now." (10.17)
This is an example of how people inside the Dome feel about the lie: the only way to make up for their cowardice is to kill themselves. Death is a way to escape the lie.
