Even when I did find a balcony with glass around it I still couldn’t cope. I have lost 1/2 my life, any chance of a career, family & friends. 23 yrs following ross river, EBV, barmah forest unfathomable pain, mcs last 12 yrs. I did 5 yrs in a car. Annie hopper program saved my life.

However by the end of the battle there's something most fans do not notice, Sasori wasn't killed by anyone, he killed himself. Chiyo was poisoned, and Sakura was stabbed badly and already weakened enough to die, Chiyo herself confirmed that Sasori jumped into the trap himself, if Chiyo was on her own he would've killed her simply with his poison, if not then with anything else.

1. Sakura Vs Shin

If Sakura was on her own she would've been done for since the very first attack which was the senbon needles/threads from hiruko's mouth and left arm. And through his battle with kankuro you can see that Sasori actually wanted to become an eternal piece of art along with his parents which was the reason he allowed himself to get killed when Chiyo used his parents to kill him.

Sakura Vs Shin

Think of it like this, how can someone in the age of 15 with no weapons stronger than a few puppets made during the village war, take down the third kazekage? The third kazekage was known as a very fearful weapon in the shinobi world and in the history of the sand village for his iron sand abilities, how can someone who took down such a person, get killed easily like that? It doesn't need much logic, Sasori had allowed himself to get killed, he let his guard down that's true but he could have finished both of them off if he actually attempted to really kill his grandmother like he'd took down plenty of villages on his own with his puppets.
