When Is Birth Unfair to the Child?

Is it wrong to bring children who will have serious diseases and into the world? In particular, is it unfair to them? The notion existence itself can be an injury is the basis for a recent new tort as "wrongful life. " This paper considers Feinberg's theory of harm as basis for a claim of wrongful life, and concludes that rarely can the conditions imposed by his analysis be met. Another basis for that it is morally wrong to have children under extremely adverse is suggested: a principle of parental responsibility. We also argue having children under such conditions may be unfair to the children, even they have not been (in Feinberg's sense) harmed. Finally, we consider when are sufficiently awful that having children might be viewed as with being a good parent and unfair to the child.
