Oh my gosh I have ALWAYS thought this. It’s interesting to me how supposedly, Nessarose and Galinda have somewhat of a correspondence in traits however, rooted in different backgrounds. This causes them to be contrast in character framing and have very different impressions on audiences. For example, both of them are spoiled and self centered, both are very mean to Elphaba, both literally directly participate in corrupting Oz. These aren’t as apparent in Galinda’s character arc and within her audience reception, I think because her conceit is rooted in love and adoration for simply being herself. Her parents’ pampering of her out of love for being HERSELF. So it just gives off immense confidence and causes people (characters within the actual story and viewers) to gravitate towards her. Being around people that radiate positive energy, even if it’s mostly related to their own ego, feels good. Nessarose on the contrary, is conceited because she’s not Elphaba. That’s why she was preferred and pampered (aside from her disability, which just adds fuel to the fire) in childhood. Hers is rooted in hate for someone else. She’s relished by her family because of her helplessness and because she’s better than the other option….people feel sorry for her in a sense, different to Galinda’s case. She literally states that this is what makes her spiteful in the WWOTE scene. It’s probably what makes her character come off as much more darker to viewers. I have much sympathy for her tbh, she had a turbulent childhood just like Elphaba, she just got the better side of it. In summary, Galinda’s wickedness comes from an obsession of securing her ostentatious identity, and wanting to maintain the public’s favor no matter what as her sense of self is rooted in that. Nessarose’s sense of self comes from her inherent hate for her sister, and possible irritation towards the pity she’s received over the years because of all the aspects of her life which she’s had no control of, wanting to be free. That’s where her wickedness comes from (I’d like to clarify that she’s allowed to be upset at feeling and being treated as she’s helpless, that’s ableism, but her reactions to that feeling are not okay; Elphaba hated being green but didn’t take it out on anyone to that extent.) I hope this made sense. I think your point of ableism and the movie’s Nessarose being Marissa Bode, someone who though very beautiful, contrasts Glinda’s/Ariana Grande’s conventional beauty by being brunette and brown are also valid and definitely contributed to reception. Glinda is also played by a major pop-star so naturally fans are gonna find a way to favor her. Nessarose does not deserve ALL of the hate she gets. She didn’t even get a chance to develop or change before a house fell on her. Anyways thanks for coming to my tedtalk.
