I think the ambience and music in the last scene make it pretty clear that she is slaughtering all the guests out of revenge and that something twisted and evil is happening; they cannot reach her after all.

And the decision she made was between eating a sausage and a living being tyring to help her. She chose the living being. Yes, she avenged the deaths on the Maw (the Punisher has a page in here as well, by the way) but turned to the "Dark Side" to do so and is pretty much villainous at the end.
