I am not an expert in dog behaviour, but I will post to offer a 'general public/dog appreciator' opinion. To me, once a dog bites a human, that dog is and should be at high risk of being put down.
If you are willing to do the work to train her, she may be able to be rehabilitated. (We had a dog who was a fear biter when I was a child, and with a behaviourist he was rehabilitated and never bit again, after biting me twice and a neighbour girl once). I know it's possible.
But. If you don't have it in you, that is fair enough. I'm surprised to see so many guilting responses here, honestly. The dog bit somebody with no objective provocation and no warning. Choosing to work with that is a risky decision. Choosing to give the dog back to the rescue, or euthanize, in everywhere but internet-land will be considered a very sane choice to make.
