I responded to the comments not the threads specific subject. See my comment about my aunt and tell me the doctor should go to prison.
Pain is awful. I had a time in my life where there was literally nothing else in the world except pain. I couldn't carry a conversation, talk or even think about anything except the pain. Refocus technniques had little effect. Pain was all that existed. I can understand completely wanting to end pain. That said, it's not my place to judge your aunt.
My mother-in-law was in a hospice for months, knowing that any moment might be her last. She was in intense pain. She couldn't keep food or water down. She was surrounded by dying and mourning people. She was 1000+ miles from all her family except her 75 year-old diabetic husband who was barely able to live by himself. When she somewhat stabilized, she was moved closer to her family and another doctor determined that the diagnosis that put her in hospice was completely inaccurate. After appropriate medical care, she lived another 17 years.
I used to believe that assisted suicide was a reasonable option. I no longer do.
