"I've never wanted to do something where I'd berate the audience"

Roland Joffe's quote recommends that he is not interested in producing art that would be viewed as insulting or degrading to the audience. He is likely describing the type of art that is developed to shock or provoke the audience, instead of to entertain or inform them. This might be translated as an indication of respect for the audience, as Joffe is suggesting that he does not want to create something that would be viewed as ill-mannered or offensive. It might likewise be viewed as an indication of confidence in his own work, as he is not counting on shock value to accentuate his art. Ultimately, Joffe's quote recommends that he is interested in creating art that is meaningful and interesting, rather than art that is designed to merely provoke or upset.
