My thoughts are that an individual’s conscience does not matter one whit when it comes to the the murder of another human being. The primary concern is for the unborn child.
When Person A (i.e. unborn child) is incapable of making a life or death decision for themselves, then it is nice to have someone, Person B, who can be trusted to make decisions IN THE BEST INTEREST of Person A. When, in “good conscience”, Person B elects for the slaughter of Person A, because it is in the “best interest of Person B”, then Person B clearly cannot be trusted to make any decisions regarding the welfare of Person A.
Amen.
