No, she isn't. If she had the humility to say, "OK I've listened to all of the doctors, the nurses, the judges, and heard what they have to say, and I understand that it's the only way forward," EVERYONE would have sympathy for her and comfort her.
She's not a desperate mother trying her best for her child. To suggest that this is how a truly loving desperate mother behaves is an insult to all of those who have lost children without attacking, insulting, threatening and denigrating those caring for them.
