Not true. If they believe in Gods, go to church and commit heinous acts. They are still the Religion they claim they are. You don't get to claim who is or is not Godless, as it's not your belief. Only they can say whether or not they do.
It is their own scriptures that condemn such actions and also offer they are not of the Faith they claim, if they do not practice the required Virtues.
Would you like to explore that concept.
