There literally isn't a way she comes out alive. And actually, the gm is law. What he says goes. 

And to be honest, it wouldn't be fair if she lived. You may ask why and I'll tell you. The titans screwed up on this one. They waited to long to try and save her and punishment is called to do it. If she lives, then that is a major exploit saying that y'all can make countless mistakes without punishment.
