Now, amoral and atheistic managers, those people would have absolutely zero qualms about things like that. In fact, I vaguely recall stories about priest impersonation during early Soviet history but I may be just inventing things on the spot here.
This action is just as likely to be done by anyone not caring for the Catholic church, which includes (among others) agnostics, Muslims, hindi, christians that don't believe in hell, christians that want to be evil, etc.
It's safe to say that the person in question was a psychopath though. Nobody with healthy empathy could do this.
