The home, which was run by an order of Catholic nuns and closed in 1961, was one of many such institutions that housed tens of thousands of orphans and unmarried pregnant women who were forced to give up their children throughout much of the 20th century.
In 2014, historian Catherine Corless tracked down death certificates for nearly 800 children who died at the home in Tuam between the 1920s and 1961 — but could only find a burial record for one child.
It wasn’t a septic tank.
It was a structure with 20 compartments which was originally designed as some kind of sewage management system but was never used as such.
So your question is really, do I think they had a valid and good reason to bury 800 infants, who had died from various bacterial and viral infections over a long period of time.
The obvious answer to that is yes.
It was a refuge for mothers and children. There’s no indication of any abuse or neglect of the deceased at this time. I’m sure there are many valid criticisms to be made about this time and this place, and certainly there are valid criticisms to be made about religion, but this refuge is not the baby murder facility you’re looking for.
There’s a snopes article with a lot more information which challenges the assumptions you’re making:

Except that Snopes article does not even agree with you.
It’s time you stopped excusing and glossing over the atrocities committed.
