I'm often reminded about a case in my own country: a young person had decided it was time to end her life after struggling for many years, without a sign of improvement. She was denied the right to euthanasia. After multiple failed suicide attempts, she went for the nuclear option and jumped in front of a train.
Everyone deserves to die in a dignified and humane way, not in multiple pieces or with a mind deteriorated beyond recognition. Forcing prolonged suffering is unnecessarily cruel. I wish more countries were as progressive with euthenasia as Switzerland.
