Arguments for organ donors?

Science. Organ donation isn’t just for transplantation, they can also be used in research to help fight disease and further progress the human race. Donating your entire body as a cadaver gives medical training to students and the organs can be used to research any ailments you had.

pro

Ensure you are dead. One eccentric reason for organ donation is to prevent being buried when you are not really dead. There are many cases of people suffering from something like a diabetic coma where they are pronounced dead but really aren’t. Some of these unfortunate people have woken up in coffins days later (evidence: claw marks in side upon exhumation). If you donate your organs there is a guarantee you will be dead and not wake up buried alive.

pro

Help people. The biggest motivator for organ donation is helping people who desperately need it. After you die your organs are of no use to you anymore but may help save and give someone a better life.

pro

Family. A common occurrence when an organ donor dies is to challenge the authority you gave for your organs to be donated because they done want their loved one to be ‘harmed’. A lot of the times the ruling falls in favour with the family and the organ donation policy falls moot.

con

Desecrate the body. The body should return to the earth just as it came and to desecrate it would be sacrilegious.
