Terri had a surgically implanted feeding tube. Different than an oral feeding tube.
If Terri had put her wishes in writing, would that be euthanasia if her feeding tube were removed? You're dodging my question.
An IV is surgically implanted. But no living will can contain instructions contrary to law. SO is she asking for the equivalent of suicide? Apart from that , what is the justification for killing someone who is not suffering? Is it justified to cause suffering to end a life that is " not worth living"?
