The religious orders claimed (and claim to this day) to represent and speak for a merciful god: they claim the moral high ground, answerable to a greater power than State or human brotherhood. They were all-powerful in Irish society, because they controlled (and still control) the formation of the Irish character. They may have been "doing their best" as is being claimed by their apologists; if that was "best" there is no just god.
The religious formed the minds of those who drafted the Constitution, of those who made (and make) the laws. They gave them the "moral formation" that made them cruelly complacent in the face of misery. Further, they profited financially from the bleak hopelessness they imposed in the name of their "merciful" god.
Theirs is the moral turpitude. And as in the case of restitution for the thousands who suffered in the industrial schools, they must, in decency, be made to pay for the manner in which they warped our society.[link]
