In my view, two truths must guide any decision: (1) The parents must be sovereign, but (2) the parents are sometimes wrong.
I believe that in this case the parents are wrong, and the doctors and judges are right. Charlie’s suffering is literally unimaginable and we are simply prolonging it. This is a life of no light, no sound, no motion, only moments of physical suffering (seizures? intubation?) to punctuate the darkness. His doctors understandably believe that allowing a natural death is the most merciful thing they can do for Charlie.
As for miracle cures, I share the court’s skepticism. They always arise in such cases, and invariably prove to be cruel deceptions.
And yet. Despite all these considerations, I would nevertheless let the parents take their boy where they wish.
