What is so horrible, that the choices weren't that MS has to kill her or forever be "saddled by Terri" -- Terri's parents begged to be able to take Terri and take care of her, and MS and the judge denied this option.
As I occasionally say, even animal shelters that are about to destroy stray animals allow them to live, if there is someone willing to adopt them. Terri's life was considered to be worth less than that of a stray animal. She was deliberately, brutally put to death, instead of allowing to live out her natural life among her loving family.
You can't get any more cruel than this.
No, you can't.
