'Public institutions do not commit evil'? So what of institutionalised Nazism? What of the institutional Catholic Church and its persecution of Jews? It's persecution of its own people under the roving tribunals of the Papal Iquisition? Such institutions comprise individuals and allow them greater scope and facility to commit evil. Why do you think that evil, historically, has typically sought the vehicle of public institution to manifest itself? There is power in institutional organisation.

The questions you raise about church were initially a red herring to avoid the matter that I raised with you: the need to stop misapplying the word 'Church' to the Magisterium of the Church. I even went so far as to prove to you, catechetically, that your misapplication of the word 'Church' was actually at odds with the teaching of those you regard as constituting the Church, that is, the bishops. Unsurprisingly,  you 'ducked' this issue.
