Why do Ginny and Rose seem so much nicer in A Thousand Acres than their parallels in King Lear?

Since A Thousand Acres is written from the point of view of Ginny, it makes sense that which characters seem good and which seem evil would change. In A Thousand Acres, it appears that Larry and everyone on his side is in the wrong. Although the entire conflict is mostly the result of a misunderstanding. Larry is crazy and thinks that everyone is trying to steal his farm. In this version of the story, nobody seems really good or evil. Everyone in the story makes mistakes so it doesnt really seem like anyone is actually good. However, nobody is entirely to blame for the whole conflict, so no one is really evil either.
