O'brien as a victim
I do not believe O'brien is a victim. I believe that the only reason he does not think the way that Julia and Winston do is because of the luxury that the party provides for him. He does not see things the way they do because he is given the basic needs and more that they do not. they live in garbage homes, eating basically trash and drinking jet fuel while O'brien is given a spacious manor with normal food that we take for granted every day. He has the choice to try to do what is right and revolt but he does not because he is comfortable with the things he has been given. As long as he takes what the party throws at him he gets to live a comfortable life.
