Everything that happens can only happen with Hashems approval. And part of how He runs the world is that bad things happen like the Holocaust.
Our job is to keep the mitzvos the best we can and maintain our emunah. It’s all somehow for the ultimate good. In the meantime we’re very limited as far as what we could see. We don’t know what the outcomes will be. We just have to keep the Torah the best we can.
