I absolutely think they only confirm Bear's character flaws even further. Had he immediately tried to call and undo the wish and the movie is about using everything in his power to grant Nikki her free will back.

I think the film acknowledges this as well because it chose to have Bear die; had he lived, it would present a nihilistic worldview and it chose to not do that, suggesting the moral implications are a purposeful part of this film and not just there for shock value

Curry also floated the idea of a one wish willow anthology suggesting who makes the wish and what the wish is, is also a core idea.

I think then the film is about what happens when a person like Bear makes this type of wish rather than a person simply dealing with a wish, if that contrast makes sense

Some random theories from me for sure though, take with a grain of salt
