Bruh I'm trying so hard to ignore that Sasori hasn't betrayed the Sand village yet. Sasori betrayed and killed the 3rd Kazekage which made Rasa the 4th Kazekage. To further strengthen his post, Rasa declared war on Konoha which started the 3rd Ninja war. Pakura was Rasa's main competetor for Kazekage's position. That's why he sent her to sure death mission.
Wrong, Sasori has already betrayed the sand I have mentioned this briefly in one chapter, and no the war didn't start after Sasori killed 3rd kazekage. 3rd Kazekage was alive when the war started he was killed during the war. You are right about Pakura, I changed her age and the time she was killed so that messed up things a bit by not too much. I also mention about this briefly in chapter 63 which will be chapter 65 on webnovel
