State sanctioned murder

This.

This I cannot understand.

I am at a loss to understand how a child can be denied food, water and oxygen, and essentially be held prisoner in Britain under the guise of “healthcare?” CNN:

Judges on the UK Court of Appeal once again ruled against 23-month-old Alfie Evans’ family.

Wednesday’s ruling rejected new arguments intended to overturn a decision by the High Court on Tuesday that prevented the terminally ill toddler from leaving Britain for medical treatment, said Roger Kiska, a lawyer with Christian Legal Center and part of the legal team representing Alfie’s parents.

As staunch pro-life advocate, I can grasp the legal arguments in in favor of abortion, even if I vehemently disagree with them and think they are wrong.  I can even understand the legal arguments that resulted in the death of Terri Shiavo, even if I vehemently disagree with them and think they are wrong.
But this?
How does the British court justify this willful taking of life?  How does British society justify holding this child prisoner in a country that refuses to even try to treat him, while denying him the elements of basic sustenance?
Last July, Charlie Gard was killed under similar circumstances.  CNN:
At the end of January, Charlie’s parents launched a GoFundMe page to raise money to bring Charlie to the United States for that treatment. In three months, they exceeded their £1.3 million ($1.65 million) goal to cover the costs, but the hospital stepped in and opposed this effort, stating that it was not in the best interest of their patient.
In February, the hospital decided, based on Charlie’s status, that treatment was unlikely to benefit Charlie. Unable to agree, the hospital went to court to have a judge decide, hoping to be able to remove Charlie from life support.
I have no special insight on this, just utter despair.  Is there no way to just take Alfie out of the hospital and fly him to Rome, where he has been promised care?  Is there no one who will defy this inane British law and rescue this sweet boy?
What is the state’s interest in making sure that he dies?
Say a prayer for sweet Alfie and his poor tortured parents.  We are living in evil times. Our regard for the sanctity of life has dropped so low that this boy can be killed on the world stage while we all stand by, helpless to do anything.  This is so very wrong, and we all know it.
How can this be called anything but state sanctioned murder?
