@Sasukefan7849 Sasori didn't have strong motivation to fight while reincarnated. Also Kankuro had Sasori's human puppet in their rematch, while Sasori was in his human body lacking the modifications he had inhabiting his puppet body.
This happened already. Sasori beat him while he was still in the hiruko shell. And Kankuro will always lose to sasori. If he is not using a puppet, he made himself.
