This is what I am saying, you do not have the right to kill a human whether it is your life or a life of another person.
No, but you also can’t force a person to donate their body.
If you died and either hadn’t chosen or expressly forbidden that your organs be donated they couldn’t use them. They could not use your body to save the life of another person. Even if you were dead and they were no use to you.
Even if you were a perfect match for a person.
Even if that person was a child.
They couldn’t force you to save their life.
Why don’t I get the same rights over my body?
