I believe Organ Donation should be mandatory and not opt-out/in
In my perspective after death we no longer exist and thus can’t own our body or organs anymore. Therefore we should have no say in what parts are used to save lives.
I believe that a person stops existing after death. What you wanted while you were alive should not matter at all when the body can be used to potentially save lives. I also don’t believe family or friends should have any say.
I have lost close family in the past, and I definitely understand the will to keep your loved ones “intact” in a way.
When these are the options it seems clear that feelings should be ignored and the family can bury whatever isn’t useful.
