An ethics of mercy (Immanuel Kant, Ayn Rand, Aristotle)

Moral theories seem to ignore facts of human life such as birth, childhood, and events threatening the physical, emotional and social development of human beings. Such moral systems are unfinished because they are built upon the needs, concerns, and choices of adults dealing with adults, but defenseless people are ignored. An Ethics of Mercy will show that Kant's theory implies an ethics of mercy, which he didn't develop. Further, both Aristotle and Rand need an ethics of mercy to complete their views. None of them explicitly addresses mercy as a rational, necessary and universal moral duty. Through acts of mercy, as caring for humanity because of the dignity human beings possess, we are just being human and doing what humans ought to do. Acts of mercy, done out of duty, reveal our real human nature as defined by Aristotle, and help us to become fully moral beings as Kant envisions.
