Withdrawal of life support is not directly causing harm.
If a child is being kept alive by heroic medical effort then withdrawing support is simply letting them go.
'immediately ending the suffering' is something else. It's actively killing a child. As I said previously, it's easy to make a case that for this particular child that was a good thing to do, but what we are discussing here really is whether we should change the law in the UK and any change in the law will affect all of us.
The recent failed bill would have legalised AD for adults with capacity to consent who had less than 6 months to live. Many of us have been warning about a slippery slope of widening criteria and we are continually presented with handwavy arguments that of course there will be lots of safeguards and there's no reason to think we'll end up like Canada or the Netherlands or Belgium.
But the threads are full of people arguing for AD for people who do not have a terminal illness or who do not have capacity to consent, or people with MH issues, or people who don't want to be a burden, or people who don't want their children's inheritance eaten up by care home fees.
This thread has presented a new one to me - AD for people without capacity to consent whose relatives do not want to be carers.
The more of these arguments I read, the harder my 'No' becomes.
