I think you are looking at this the wrong way. Sounds like she lived a long and happy life. K is not a guilt religion, or a religion for that matter. We are not in control of other people's destiny. Many beings can connect with the spirits of living, and those who have passed on. You may have sensed that your friend was going to move on, and your spirit was there to support her. As far as causing suffering and pain, her death does not sound like a bad way to go to me. When my mom was dying, it was a long painful experience. All 3 children were there. My mom had always told me she wanted drugs. Morphine was sitting right there by her bedside. My brother, however, was more of the she will leave when she is ready philosophy. In desperation, I called an old friend who had been through a similar experience with her mom, who also had Alzheimer's. Her advise "your mom will only be around for a few more days after a wonderful life. You are stuck with your brother for a lifetime." The only choices we can make are those in the present. The same goes for everyone else. On a positive note, I do hear from my dead friends and relatives when I need them most. Especially right after they die. Your friend may come to you in dreams or other ways when you need her most. Sorry for your loss, and may you find peace and forgiveness in your journey. It is not what happens in life, but how we react in the present. There will always be pain and suffering. Guidance is there every second of the way if you care to see it in everyday life.
