You are SO sweet to try! If they are meant to be spared, the way will clear for you to get to them. Perhaps they wouldn't make it anyway. (Not trying to be crass, just realistic. Believe me when I say I'd be doing what you are.)
If nothing else, you did your good for the universe by taking on this one. He/she was sent to you. I think it's the Japanese who say that if you save a life, you become responsible for it. Boy is that ever true!
May God bless you for all your efforts.
