Ivan Karamazov

Yes, I think it’s better if we understand the context, Russian history, etc.

Great question. I’m would need to review the book to answer that though, and that’s a lot of book. Could you be more specific. Maybe link to a particular passage?
Here is the rebellion chapter: https://ebooks.adelaide.edu.au/d/dostoyevsky/d72b/chapter35.html Here is the famous Parable of the Grand inquisitor: https://ebooks.adelaide.edu.au/d/dostoyevsky/d72b/chapter36.html
I don't want harmony. From love for humanity I don't want it. I would rather be left with the unavenged suffering. I would rather remain with my unavenged suffering and unsatisfied indignation, even if I were wrong. Besides, too high a price is asked for harmony; it's beyond our means to pay so much to enter on it. And so I hasten to give back my entrance ticket, and if I am an honest man I am bound to give it back as soon as possible. And that I am doing. It's not God that I don't accept, Alyosha, only I most respectfully return him the ticket.
