Like, basically, there is no implication that Wanda doesn't know she's enslaving people. It's moreso basically... She has convinced herself that, since she has created this fantasy world that SHE is happy in, they are also happy in it, even if against their will. And then when it is made clear "No, you are literally enslaving these people and ignoring their feelings for your own," she starts to come to terms with it... Until she sees her family, and literally starts to put the hex back up because, again, she's thinking about herself over them. She's incredibly selfish throughout almost the entire series.
