"I was just following orders" didn't fly in the past either. Ignorance is not a weapon, it's a weakness that many people use to protect themselves from "inconvenient" truths.

Whether they tell you or not, the FM worship lucifer, a fact that is hidden from lower level members. They only share that fact with higher level members they're pretty sure will accept it and not divulge it.

Just because you haven't been informed of that fact doesn't mean it isn't the case. Do some research on the topic with an open mind and see how you feel afterward.
