While the argument is logical that all participating in carrying out an abortion, if its illegal in the land...that extension of the law would make it that abortion would Never become illegal.
there is no way any state or jurisdiction would prosecute the docotr, the womand and the spouse.
Once abortion is made illegal, it would be in unjust to classify to types of child murder as different, one with the killers receiving harsh punishment and the other where the killers are not punished.
