If you are not an organ donor (by choice), you should be at the end of the list for transplants if you need one. CMV

A lot of people I know are not organ donors because of reasons like "I want to keep my body when I'm dead" or other, rather honestly, tenuous reasons.

I believe if you actively choose not to be an organ donor, you should be considered last for transplants if you need one. Why should someone else's sacrifice go to someone who wouldn't be willing to do the same?

Note I said by choice. I'm under the impression that if people won't donate because of religion (although I disagree with this, but this is besides my point at this time), that they would not receive organs for transplantation as well. In addition, people who are not legally capable of making this choice are not subjected to the title (children, for instance).

Now I'm not trying to generalize my experiences I've had with people who would not register as an organ donor, but I feel like it will still provide an interesting discussion otherwise.

It is not for the medical community to decide who should live and who should die. There is nothing that you can do to make yourself less worthy of medical treatment. 

Now, because resources are limited and important resources like organs, the people in charge of distributing those resources may sometimes have to decide who *can* live. That requires them to decide who will get the most use out of the resource, they must judge who's health will likely be most positively effected. 

But doctors and transplant boards are not judges and juries. They do not judge whether you deserve an organ, just whether you're likely to get a certain level of use out of an organ.
