Compare that spiritual callousness with the Buddhist practice of mizuko kuyo, those fairly common religious services in Japan to commemorate the souls of departed fetuses, complete with rituals, prayers, and burial practices.
However, one of the most common belief is that of the mizuko worship is the flipside of the curse - that an aborted fetus will haunt and cause misfortune upon the mother that caused its demise unless properly "blessed" through religious ritual, and even then - an "improperly" done ritual (or many other variables like the ritual not done to the frequency of the liking of the fetus ghost) will not "cure" the situation.
Some information of the mizuko concept here, including positive aspects, is here.
