Both. If someone's not loyal when they're in your party during the final fight, they die. I thought keeping her in my group would keep her alive because I figured Bioware wouldn't think to program someone dieing while they're in your party.

Someone told me leaving her with the defending party would have kept her alive so long as Grunt and Zaeed were there, but I don't miss Jack enough to replay the mission. She pisses me off just as much as Ashley.
