You know scripture is silent on this.. Some theologians in the early church disagreed on when a baby received their soul,so this matter will not be resolved by men ..this is an area that belongs to God...
I would not consider the babies as martyrs as they are not being killed for the faith, they are being killed by selfish women that place themselves above God and their interest before the interest of their own child.. One thing I do know is if mom does not repent she will see eternity from a painful position
The Church has ALWAYS considered the Holy Innocents to be martyrs, they died because Herod was trying to kill Christ.
Aborted babies die because the culture of death, on behalf of Satan, is trying to destroy Christianity.
I’m not saying this is theologically correct, but it is theologically possible.
