Why did Kakashi kill Rin in Naruto Shippuden? Explained

Naruto Shippuden and the tales related to it are like a discussion that can go on for eternity. While some of the stories were fulfilling, the others were gut-wrenching. And when it comes to tragedy king Kakashi, most of the events were heartbreaking until he grew up. One such event is when Kakashi took the life of Rin. Despite being discussed a lot amongst the cult fans, a majority of followers still don't know the reason behind the heartbreak that sent Obito Uchiha on a dark path and forced Kakashi to shut down his emotions.Moving ahead in the article, let's have a look at the reason behind the tragedy. Kakashi, Rin, and Obito were on a mission first, where Obito got severely injured. Knowing that he will die for sure, Obito gave his one-eyed Sharingan to Kakashi and asked him to protect Rin at all costs. In the Third Great Ninja War, Rin was kidnapped by the Shinobi of the Hidden Mist village. And she was forcibly made the Jinchuriki of the Three Tails. The plan of the Shinobis was to let Rin go to Hidden Leaf village, and as soon as the beast unleashes, it will destroy the people and the place. However, Kakashi comes to rescue and tries to take Rin to the Hidden Leaf village (so that they can solve the three-tailed problem with the help of elders). Due to constantly being attacked by enemies, Kakashi pulls off Chidori to eradicate the enemies. And the mishap happens here as Rin intentionally jumps in front of Kakashi. She did this to save Konoha from the attack of the three tails. The moment was not only shocking for Kakashi but also for Obito. The Uchiha saw the scene live and thought that Kakashi had betrayed him and broken the promise to keep Rin safe. This was the main reason why Obito went rogue (along with him being manipulated by Madara Uchiha) and in future became the initiator of the Fourth Shinobi War.
