It would make you think that the knowledge of parishioners transgressions were really, really important. Who would ask for access? Who would request old data?I'm pretty sure deep down the MAA was glad. He got rid of the work, did not have to check all the bs accusations and best of all - some other poor shmuck did it for him and took the blame.
Deleting or destroying data was seen as an act of radical sabotage back in my day. Being assigned to lower conditions would be the very mildest of possible outcomes. Getting kicked out of the church or assigned to the RPF would not be out of the question, depending on the importance of said data.
Data was holy and never ever ever to be destroyed. Example:
We had digitized transcripts of 20 year old confessionals that have been originally recorded on 8mm tapes. Some dead souls must have been assigned to listen to all these tapes, then manually type all of the dialogue into our CRM. Just one more illustration how the church always find ways to waste the work-time of its staff and SO.
