Have to admit I'm kind of uncomfortable with this kind of thing being allowed. While I'm fully supportive of allowing voluntary euthanasia for terminally ill people who know full well that there is nothing but pain ahead for them, this is a girl who really did have a life to live.
I don't want to in any way trivialise or claim I understand what she went through, but I find it hard to believe that the trauma and mental conditions her abuse brought on are so irredeemable that there was no hope of her being able to ever enjoy life again. Elizabeth Fritzl, as a comparison, has apparently managed to live a relatively normal life despite being imprisoned underground and raped by her own father for 24 years.
