What would be fair is if the monster went to jail where he belongs.  If the monster is no longer alive--I likely would not punish those who had nothing to do with the abuse--unless the actual person was responsible for covering it up or enabling it in some way. Then I would want that person or persons to go to jail.

If I was at all inclined to sue, I would obviously go after the religious order.

In answer to your question: there is nothing that would make up for the abuse--even if the monster went to jail and all those who enabled him, even if I sued and received a huge payout.
