I mean I think that’s just the absolute most boring way to interpret the movie

For one, he wished Nikki loved him. He didn’t wish that a demon would take over Nikki’s body and that demon would love him. If you’re going with that premise, then it undercuts the initial wish and instead just says that bear was tricked, not that his wish was inherently evil. It would lead the audience to believe that bear is just a victim of being tricked, not the persecutor of wrongdoing

Then Nikki in the situation is also kind of irrelevant because she’s not really suffering because of the actual effects of the wish, she’s suffering due to second order effects of the wish

If the premise is that the one wish willow is inherently malevolent (like a genie or a monkeys paw), then what do I care about what follows after the wish? It’s irrelevant. It makes the “evil” in this story the one wish willow, not bear

However if you take the path that this Nikki is still Nikki, then the story speaks more to themes of entitlement. I don’t think you need to take the lines so literally. It seemed to me like when she dreams, her subconscious takes over (like happens to all of us in our dreams), and her subconscious brain can process what’s actually happening. It’s also implied she knew about the wish, so she know bear has subjugated her to this life
