Books about the cycle of violence and the consequences of oppression and domination?

Obviously the Israel-Hamas conflict is on many minds. I find the situation unbearable. But I don’t want to get much into my thoughts on the situation as that’s for a different sub. What I’m interested in are stories that are much like it. Stories about the never ending cycle of hatred and violence that continues for generations as well as stories about oppression and the consequences that come from it. It’s an Anime/manga but I think Attack on Titan does a masterful job at portraying these issues. I’m wondering if there’s a book that does so as well?
