finished crime and punishment, what next?

I just finished reading Crime and Punishment and it really stayed with me. I loved how deep it goes into the character’s mind, the guilt, the moral questions, and the slow psychological tension. Raskolnikov constantly arguing with himself was more interesting to me than the plot itself.

Now I want to read more books like this. Stories that focus on inner conflict, philosophy, and flawed characters. I am thinking about books like The Brothers Karamazov, Notes from Underground, or maybe something like The Stranger by Camus.

What books would you recommend if I want that same heavy, introspective feeling? Should I continue with Dostoevsky or try other authors with a similar vibe?
