Since the text specifies that Marae is alive and well, I assume that when it says the factory was destroyed that it means the option that shuts it down but doesn't release demon juice into the lake and fuck everything up long-term.
Fair, but I'd say being turned into a demon still qualifies as "alive and well" just from a different point of view. I may be jumping to conclusions. Reading the factory as "destroyed" and not "turned off lol" makes me think the demon juice flowed.
