I'm not sure specifically as I haven't read this novel in detail. But generally, the main characters would be those who drive the plot forward, who face the main challenges and conflicts within the 'dark' context of the story.
The main theme could be about the shared human experience in difficult or dark times. It might explore how, regardless of our differences on the surface, we all face similar struggles and emotions when in the 'dark' situations of life.
Definitely not. 'We All Fall Down' is a work of fiction. The story and its elements were made up to entertain and engage readers, not to represent actual happenings.
We can learn not to let fear and superstition guide our actions, like in the Salem witch trials. Fear made people do terrible things, so we should always base our judgments on facts.
Well, it might offer a realistic portrayal of events. It could show the real struggles, emotions, and situations that the true story was about. Maybe it'll have characters that are complex and relatable, just like in real life.
