This doesn’t accord with her ideology, for sure, but in practice, the more Belle is being portrayed as an irrational, hysterical shrew — as she is in this season — the more her more positive qualities (seeing the best in people and forgiving them) recede to the background or just come across as whimsy, rather than actual moral commitment
Her positive qualities, possibly only quality, is that she’s smart and that only occurs when the writers need someone to explain “the thing” and they can’t get a supporting actor to do it. She’s Google. The issue is also that that singular positive quality is becoming increasingly hit or miss. One of the biggest issues is that Belle has never really been a consistently written or fleshed out character. She’s a device through which the writers explore Rumple and his redemption, or lack thereof. I think this is why while everyone agrees that Rumple is basically a crappy person, everyone gets on edge about Belle and her “abusive” nature (or call it what you want). It’s because she’s never really felt like a solid character.
