@bookstodon@diazona I 100% agree with you on both. That question could be interpreted many ways. Werner’s unease over his actions as a member of the German army is absolutely the driving force of his section of the novel though!
As to other ways character flaws can drive a novel: I just read The Prestige which has an unreliable narrator and 91% said flaws are a main driver of plot. Plus it is a great book.
