The Novus Ordo isn't the problem. IMO, there were men being ordained priests back then that had no actual vocation to the priesthood. They were shoved through the seminary with no actual care for whether they'd be shepherds for the Faith or not. And it's clear a lot of them were meant to be laymen.
The vast majority of these photos are from priests formed before the Council and slightly after. That group of priests is the most responsible for not only liturgical abuse, but the sex abuse cases that rocked the Church.
