Still, in the end Ciri says that it is her decision (you can ask her that) to become empress. Of course she then will not be as free as living a Witcher's path and this choise may be due to rationalisation, but still; she does it because Ciri wants to do become empress because she sees that this is the best for the majority. For Ciri to be the empress, you need both Nilfgaard winning and assassinating Radovid. if one of these two conditions aren't met, Ciri becomes a Witcher. Those three choices combo you mentioned are my exact choices in my most recent two or three playthrus and in all of them, Ciri becomes a Witcher, assuming I didn't get her killed. No one can force Ciri to do anything now that the Wild Hunt Is gone. She could literally run away to another dimension in an instant. Being Empress is exactly what she wants even if it isn't the option that would make her the happiest. In what's widely considered the game's worst ending, Ciri dies during her climactic battle with the all-consuming White Frost. For this to happen you need to trigger at least three of the puiIVxM.
