If it's her body, it should be her choice. These "people" and "children" that you believe are being killed are hardly people yet. The mother may not be able to provide for her child, or a variety of other things might happen, and then sure, you "saved" a life but instead you ruined two, the child's and the mothers. Having a baby can ruin many chances, especially if the mother is young. Once again, her body, her choice.
