These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Counterpart Comparison: A woman in a patriarchal society, is consistently abused and victimized by the male figures in her life. At some point she decides to kill her (would-be) husband, and she is seen coldly and methodically planning for the murder. As scholar Cleanth Brooks argued, Emily is Clytemnestra (The Oresteia, Electra) in a new setting.
Values Dissonance: Quite a bit. For instance, when the townsfolk believe that Emily has been Driven to Suicide and, because she's an Old Maid, agree that this is the best thing. And she was only in her late 20s/early 30s.
Some of this occurs in-story as well, between the town's older and younger generations.
