If the listener feels scandalized by what was said by Fr. Pfeiffer in those specified times, the person might suffer some level of scrupulosity.
I'm not a fan of Fr. Pfeiffer, but saying the words "masturbation", "self-abuse", "ɧoɱosɛҳųαƖ", and "self-pleasure" is not inappropriate or madness, considering he is warning people about these sins.
