I would say that the statement "Do the Church & society not have to consider the damage he suffered when deciding what to do?" a little problematic, especially when the guidance to bishops still doesn't obligate them to contact the authorities. Regardless of the circumstances, the Church shouldn't be deciding what to do, the Church should be contacting the authorities.
He said the Church and Society, not one or the other. It is entirely the Churches decision on what they do with a member who is guilty of child abuse and has suffered abuse themselves within the context of their membership and any treatment or rehabilitation they can or will offer, that they should also be reporting criminal offences to the relevant authorities is entirely right, one doesn't exclude the other.
Also while the Italian Bishops (not the Vatican) guidance to Italian Bishops is as thus ...“
Under Italian law, the bishop, given that he holds no public office nor is he a public servant, is not obliged to report illicit facts of the type covered by this document to the relevant state judicial authorities.”
it continues later to say:
“In cases regarding this type of crime where an investigation is ongoing or where a penal proceeding [trial] has been opened according to Italian state law, the co-operation of the bishop with the civil authorities will prove very important, within the ambit of respective areas of competence and with respect for both state norms and those established by the concordat.”
Again pretty vague stuff, but again it is the Bishops themselves that retain the authority to determine their own policies, this is guidance not policy.
However it doesn't say that they shouldn't, only that they are not legally required to and it also doesn't take into consideration that in other archdioceses the Bishop or Cardinal has the authority to determine the position of his diocese, and that each Bishop Conference has the autonomy to issue its own guidance, they are not beholden to Rome.
In the United States for example the current practice is to disclose all criminal offences to the relevant authorities not least of all because the law in the United States requires it, so I suppose it is dependant on the context within the entire advice to Bishops and exactly what policies are in place.
Clearly because of the actions of the Church in the past (see Vatican advice to Irish Catholics to not inform the Police in the past when the Irish Bishops were doing so as a matter of course) they should be far more robust in how they express such things and make it clear that what the law might say is irrelevant, the default position should be to investigate and report any cases of Child abuse to the relevant authorities in any country, regardless of whether they have a legal obligation or not.
