If multiple, independent tests confirm Trisomy 18, then it is the right decision. Heartbreaking for the couple.
why right
From the Cleveland Clinic website:
How common is Edwards syndrome (trisomy 18)?
Edwards syndrome (trisomy 18) occurs in an estimated 1 out of every 5,000 to 6,000 live births. The condition is more common during pregnancy (1 out of every 2,500 pregnancies), but most (at least 95%) fetuses don’t survive full term due to complications from the diagnosis, so pregnancies can end in miscarriage or babies are stillborn.
How is the mother at risk by refraining from aborting her child?
