lifechanging books like East of Eden

Hi, so I have read similar posts but I decided to still make this post as none of the other ones contain this kind of information.

So I have read Stainbeks East of Eden and liked it. it was pretty life-changing. so its theme is about good and evil, he goes back to the bible even in his references during the book.

as I feel he basically covered that topic, I don't want the same thing exactly, but in a similar exhaustive way a message about another equally important topic. so it's good if the suggestion of books would include this kind of information. like for example:

two books by the same author, Idiot, and Devils by Dostoevsky. I think both are about the same topic, also about good and evil, but that is more on background, main idea is his two main characters provide two different strategies of survival against evil. he also goes back to the bible in his references.

or Metro series, another book that really influenced my thinking like the ones i already mentioned. topics are adventure, love, and politics. also really covered those topics to the bone.

​

I have read some others like Ana Karenina and War and Peace by Tolstoy, but while they cover topics also in an exhaustive manner, the topics themselves are less important. like they are mostly about romantic and social relationships, and rules and etiquette. which is also useful of course.

another good one is Don Quijote, it's about the mockery of a hero's journey. i guess its fair to say here that reading about the hero's journey itself was pretty world shattering. meaning the book The Hero with a Thousand Faces by Joseph Campbell

something like that, a world view changing books, and in what way. if you think you have something like that please suggest.
