I feel like they're trying to wreck the machine. They keep breaking off pieces of it, tossing random stuff into the gears, and yet the small amounts of chaos this has caused in some parts (e.g. Nazis running people over, people being homeless, people dying from lack of healthcare) hasn't yet spread into general chaos.
I keep wondering if there is some critical point we have yet to cross where the damage will accelerate instead of damping out.
