My former Mother In Law passed away.
She had surgery for a benign tumor, and bled too much during the surgery. The medical decisionmakers kept her sedated for several days. They said it would give her body a chance to heal. Instead of healing, she went into kidney failure, so they disconnected her support machines and let her die. Sounds to me like this was a disaster of bad decisions starting with the decision to have surgery at 85.
I recognize that all of those decisions are none of my business. I still wish they'd made different decisions.
