The Promised Neverland is an anime and magna about a Dystopian society in which human survival is nearly impossible, until a few children at the orphanage figure out the secret of the orphanage and the world they live in. A bone chilling, yet allegorical tale of human nature, survival and the question of what is better living a short and happy life or living free and fighting for life? Isabella the "mother" of the children is a fascinating villain: warm, kind, but at the same time terrifying, cruel, and wicked. Yet, despite all this all the viewers are able to see the very human side of Isabella when they realize the truth about how the world they live in is run. Is Isabella really a villain? Or is she just a human that lived through trauma trying to make the best out of what she has in that world?
You could also go into depth about dualism tropes in film/tv/literature. I mean, what makes a villian anyway and who are we to judge? Was the Joker really a villian or a person who survived intense trauma and has many "negative" flaws and traits as a result of that trauma? – hilalbahcetepe7 months ago
