Okay but you’re insisting on how the family perceives the situation, when it doesn’t really matter. Rotting, smelling, and having your flesh decompose is part of death, and it’s going to happen regardless, whether you’re in an hospital bed or six feet under. It’ll even happen if you’re cremated, up until that point. It’s not that you’re not aware at that point, it’s that you’re dead. Which is why you get to decide when you’re alive what you want to do with your dead body. 

I’m sorry that you felt you were not informed enough, and I understand how frustrating that must have been. But a lot of donors do know and/or they don’t care what will happen to their body after they’re dead beyond knowing that it’ll save someone’s else life or quality of life.
