Just catching up a bit.
'Likely the group had become so compromised by the situation they were no longer able to function. Whether that's because they were too emotionally and psychologically damaged, or their leadership was compromised, etc.
The nuns have probably been moved into groups with stronger leadership that are more functional. Quite possibly several different ones.'
I would hope that they would have been moved somewhere together where they could get psychological support, medical support for any health issues related to what was done to them, and spiritual support to process it.
These will be very very religiously devout women who have taken a vow to devote their lives to God through the RC faith.
They have been subjected to appalling abuse. By men who were supposed to be equally devoted to God, and had taken a vow of chastity. The nuns at their hands were no longer 'chaste' and the ones forced to have abortions, that goes hugely against the teachings of the church. It's seen as murder, essentially. And God let this happen, and it was done by those of the church.
The women will surely be in turmoil. Their vows and beliefs, obviously fundamental to them, have been trampled on. They should have been incredibly safe and were not. They have been horrifically sexually abused. Some may feel guilty of murder.
Putting them on other orders is not what I hope happened. But proper long term support. And I think if I were one of them I'd want to stay with the others as they understand. Try and recover together.
I'd also worry about how they would be treated in other groups if they realise their new member is one of the nuns from this group.
