I do not believe that organ donation should be mandatory. It should not be something a government forces on to people. Let the individual make the choice. I for one would not donate my organs. It is just my choice.
Consider the person who gets the organ. They may have to take medication for the rest of their life to prevent the body from rejecting the transplanted organ. That, to me is not living.
Do you know how many people will reject this request if it is not forced?
