Pretty much from what I gathered from the game itself, is that shes not really apart of the "dark side" it seems to me shes see the force as the reason for death in the galaxy, considering at exar kun, malak, raven, sion and whoever that other guy is which because of lucas arts is never explain who he is... no back story anyway, like them and those who came before have cost the lives of millions, billions or even trillions and zillions of deaths, and see thinks of the force is removed, that infact the corruption from the dark side would no longer be there, but that's simply my take on it, theres quite alot of plot holes because of the lack of time placed into the story..... damn you Lucas Arts.
