She was doomed from being trapped in that raging fire for so long. The super hot air she had to breath literally “cooked” her respiratory system.
True actual brain death is not a life IMHO and is something you’ll come back from.
You’ll never come back from.
My father had an embolism in his sleep while he was receiving cancer treatment.
By the time he got to the hospital the bleed was over a third of his brain and was considered brain dead.
He had a living will and didn’t want to live on any machines so the decision to pull the plug in we already made easy by his wishes.
Regret his dying but not his death.
