This isn't true at all. Your post is just entirely, shockingly made up. It would make sense if the Daily Mail were your only source of facts but you're on a thread where people have posted links to the judgment, the BBC and other more sources more known for fact-checking.
She was in ITU for almost a year. The hospital didn't want to take her off life support as soon as she entered. The hospital has been providing full care in this one year. Palliative support was only mentioned recently, which we'll get to.
Over these months, her condition has been touch and go, with multiple episodes and of course an incredible level of daily medical support. From the start, doctors warned the family that she might go any time soon. They were preparing family for the most likely medical worst case scenario.
It's common for patients to not 100% fulfill the medical worse case scenario. As an example, we were told my loved one had only days to weeks to live, but they lived for months. While ST exceeded expectations, extra months – with lots of rescue attempts in between – isn't really a Jesus style medical miracle in terms of mitochondrial disease.
Again, the doctors did this WHILE providing full care for her. So realistically, the reason she lived that year was the doctors' and nurses' round-the-clock effort, vigilance, initiative and care. My own loved one was a fighter too but I won't ever pretend that was possible without the doctors' and nurses' 24/7 efforts. But the family have taken this as "well why is she still alive then? Doctors are not to be trusted".
Coming to the pallative care. Recently doctors noted that the incidences – during which doctors saved her life every single time – were getting more frequent. They noted that her body was failing in extreme ways (even the initial failure before that was extreme), on its way to full failure. Things would have got even more graphic and tragic (eg extreme pain, brain dead eventually - remember how Archie Battersbee's brain was dripping out his eyes..) if they kept manually keeping her alive just for the sake of it.
They thus advised moving to palliative care. Family said no and started the legal fight. The judgment came out quickly – it was only a capacity judgment (which comes right at the start). Then she died as doctors recently predicted (during their suggestion to move to palliative care). Doctors tried to treat and revive (as she had not consented to palliative) but did not succeed.
If there had been no lawsuit, ST would still be on palliative care at the time she had an attack and died. Basically lawsuit or not, she would've died at the same time.
I won't go into the emotional and practical weighing up of palliative care etc as it's so personal (like ST's family, I used to think it was just "giving up"; recently I have become grateful for the option of peace for a loved one in so much pain and suffering, when passing away was going to happen anyway).
But in terms of the actual effects of this whole saga, whether they had brought the lawsuit or not, she would have died at rhe same time. So I think it's a pity that they didn't just spend the last year creating loving memories with her. Of course we can't know the future, and sometimes there are religious and other miracles, but medical predictions can be a useful tool for us to make decisions on how we want to spend our time, who we want to spend it with.
Doctors don't control life and death – they can only inform us about it. Life and death control us. At some desperate point all the ITU, ICU, etc stop working (as in my case) despite doctors doing their absolute best. Seeking acceptance and closure before that, exchanging messages of love, is so important – and I hope they got a chance to do that.
