Ethics Problem

As each person's life is his or her own property and responsibility, and therefore no one can lay claim to the life of another for any form of involuntary support, their is no logical justification for one to hinder themselves from reaching their goals to prolong the life of another, as long as they did not cause the second party to be in a life threatening situation in the first place. That, along with voluntarily aiding the ailing person for your own selfish reasons are the only logical, and therefore moral exceptions.
