No one has the “right” to end his own life. That is law and it is morality. If you desire to change the law then you have the right to lobby for it. But you’ll find yourself in strange company.
My father was a neurosurgeon and he had the backbone to speak his mind. He was on the side of the INTRINSIC VALUE of life.
We have examples of how others delegate the decision making. You can characterize the hospital procedures all you want, but it's ending the person's life. And in some cases as explained by a third party. Are you proposing no removal from life sustaining equipment because you have an "intrinsic value"" of life?
If you father doesn't want to participate, he should also have that right. I don't believe doctors should be forced to perform abortions. In fact, I oppose abortions because the victim clearly is not making the decision. But the law let's doctors perform the abortion and end the life.
