You can\'t argue that it is immoral.
Not sure if your justifying the morality of it or not.
I think it should be up to the parents.
Thats the dilemna, a father may want a child, someone to love and cherish and father. A mother may not want to go through the pain, and troubles of motherhood. Who has the most say? What is going to be the chosen path?
I think the father should get the child. The mother knows the risk of birth, and knows that their are ways to control it, even if she did not have these tools, she had common sense.
Also, Sirmystiq, I know very many people that have been adopted. Just because their DNA doesnt match, their hearts do.
