The horror of a family watching their child "voluntarily"  starve to death is not leaving my mind. Which parent does that? How painful it is if one's child becomes sick, even ordinarily sick, say a severe case of gastroenteritis. How can a mother watch this for 68 days? The violence of this is mind boggling. An angry mother slapping her child is wrong, but understandable. We can lose our temper and though violent, it is nothing compared to the horrifying violence of letting your child deliberately starve to death. This is beyond understanding.
People who say that it was her choice would be the first to deny her the right to choose if she had chosen something they did not want her to do. They mean "You are free to choose if you choose to do what I ask you to."
