Very truth & may also be applied to all evil creatures that serve Morgoth & much later Sauron, just living creatures that went wrong not machines. That Tolkiens used the word device don't mean they are robots. Just that Morgoth used them for his own will, by corrupting their mind & heart inspiring them distrust & hate through lies.
