Yes, I have also been wondering since the very first chapter if she was assuming "the game" would somehow "do everything" if she just ignored it and went about her business.
If her outlook is that this is not a "real" world, with "real" people in it, then why should she care what happens to them? If it's all a simulation, a game, then none of her choices really matter; she's the only "real" person in this world.
And that's fine, right up til you die; ask any tech bro...
