"Brain washing" is considered complete when the subject follows the demands of the controller even when that party is no longer present or even dead. A person who is "brain washed" may not be able to function as normally as before even after deprogramming.
You are talking about extreme forms of brain washing along the lines of Pavlov dog experiment and so the term 'brain washing' referring to that form may also depending of the context and education of the person may simply be the zombie of a religions experience programmed by a controlling pastor.
