Much worse than I ever would have thought before I knew.
These are the sort of things that people practically never hear about. Organ donation certainly can help a lot of people; however, it should be standard to go to every length possible to ensure it's completely painless and not some terrible nightmare scenario where you spend your last moments unable to advocate for yourself as they rip your body apart.
Not to mention the corruption behind the entire operation where many times the organs don't even go to the people you'd want them to but instead go to some rich elite asshole who bribed his way to the top of the list while pressuring hospital executives to find a donor faster by any means necessary.
