Why the Pope Is Fighting for Charlie Gard

Why would Pope Francis, the leader of the world's estimated 1.2 billion Catholics, intervene in the case of Charlie Gard, an infant in the UK who suffers from an extremely rare form of mitochondrial DNA depletion syndrome? Why has the Pope joined with the child's parents in disagreement with the UK government's decision to forbid Charlie Gard's transfer to the US for an experimental therapy and to order the termination of his life support? British law vests authority in the courts to determine "best interests" of the patient when there is a dispute such as this, making it quite different from the United States.
