In the quest "The Widow's Wrath" in Kingdoms of Amalur: Reckoning I accidentally told the widow that I would kill all of the Canneroc citizens. I don't want to do this. I tried attacking her and turning the safety mode off but it wouldn't let me. When I talk to her again she just says something about how we are allies for the moment.
Is there any way I can decide not to kill the citizens and instead kill her?
