In the Carter decision, the Supreme Court claims that the right to life is affected, in the sense that this would force people with a degenerative condition to precipitate their death through suicide, although they are not at a point where they would need help. However, it is important to note that people with a degenerative condition are not suicidal. They want to live as long as possible, until they can no longer handle the state they are in, and their state can decline quickly from evening to morning. They want parliamentary legislators to assure them that, at that point in their life, someone will take care of them properly.
