I strongly hold my opinion that fiction mustn't be something we should learn from. Many authors try to hide behind characters to make the world learn something from it but they're not free from biases. The focus and attention that characters get in novels and their supposed superhuman abilities (any smallest unrealistic increment from reality) throw a learner off truth. No matter how many biases we remove, we can't get rid of them completely.

No religious books should be seen as something to learn from as they mostly have highly inconsistent stories which can influence a person to support any view. Normally, people have an opinion and blinded by hindsight bias, they search verses in religious texts which supports their opinion the most. Surprisingly, in the same text you'll find another exactly opposite opinion to yours supported by the verses.
