They have every reason to assume he would try. The original argument was: the Resistance was so close to winning Fordola had no choice but to fire the cannon at her own people because that's the only way to stop the Resistance. She can't believe that to be true and also believe that if she defected/surrendered to the Resistance that Zenos would still be able to kill her.

The non-monstrous choice when given that order is to defect from the person that gave you that order.
