I think it is right, because if the person is in great pain, would you like to be in pain? If you knew you were going to die and you were terminally ill would you like your family to say "Do not Resuscitate"?
It would be the most difficult thing for me, but considering I've already been through it and I've had to see someone die in pain, yes die naturally but die in pain, it's so painful for us as well

But it's just natural and it's life...
