Meh I am not sure they meant for her to die in that ending... For me at least, it doesn't make much sense that the difference between life and death against the White Frost is, did she have positive experiences with Geralt or Negative ones... Sounds too much like a 5 year old fairy tale reasoningI think that's a valid alternate interpretation of the scene but I think the intention by the developers is she's dead.

To be fair, I'm not sure with the Prequels why Leia was all so hot to restore the Republic. They really needed a third option. Maybe we'll get that in the new movies.
