If I was drowning in a raging river and somebody threw me a rope, I could refuse the rope and demand that somebody else risk their life to swim out to get me. When they refuse, I am not going to say that they made the choice for me. I chose to die.
I understand that I am not going to convince you. That is fine. That does not change the fact that they gave her the choice and told her the steps she needed to take. The choice was hers and she chose. The fact that they did not decide to risk or kill somebody else waiting for that organ to accommodate her “choice” does not transfer the responsibility to them.
It is tragic to see somebody destroyed by their choices. That said, I am glad that somebody that was willing to save their own life got a chance at that organ instead. I hope that nobody that I care about is ever impacted by the kind of decision making you are defending here ( the woman who refused the organ that could have saved her life ).
