It’s bad enough that most Catholic churches rarely bring the subject up but many protestant denominations are perfectly OK with abortion... 7th day adventists , Episcopalians and such .. I don’t know if they really are for murder or if they’re just sticking a thumb in the Catholics eye..
There also are some rigorous theological arguments which assert it is not murder based upon Tertullian and Augustine foundations of when the soul is placed in the baby immediately at childbirth (when God breaths upon the face, not from corporeality), rather than at conception. The counterargument is that the soul is generated by the will of the parents, rather than the will (Sovereignty) of God.
The argument may extend to the formless vs formed stages of growth in the womb and when the soul is imparted to the body.
While I would err on the side of caution, and not condone abortion, there is an additional discernible thinking process of accusation when always asserting it is murder.
It should be noted that the RCC position that abortion is murder, flies in the face of Latin doctrine expressed by Tertullian and Augustine.
