Usually people have an idea before they have a title, hmm? XD But going along with the Weeping Angel idea (and excluding Doctor Who references) you can go along with the idea that an angel in heaven is lamenting the recent turn of events, saying "this is not what we had in mind. You can go on with the idea that humans can take any concept and use it to persecute some group, but the angels and their leader are not cruel enough to annihilate us.
