Everything bad that happened in the game was because she was being a rebellious little shit, and didn't want to listen to the Two Fingers. Blaidd was even fashioned by them to protect her. As she was a potential candidate to replace Marika. However, instead of doing that? How about we just destroy the world, and start over?
The only way to reconcile this is if the Two Fingers and by extension the Greater Will is evil, but that is not that case. Everything bad we see happen is because of gods and demigods being retards, or incredibly selfish.
One of her agents, Selvius, even freaking turns people into living dolls. Like holy shit. He has a whole collection hidden behind an illusory wall.
