As stated in Jin no Sho, usage of Outer Path — Samsara of Heavenly Life Technique always results in the user's death. Konan believed that Nagato could survive, but that was most likely a lie made up by Obito to make sure Nagato would have use the technique willingly. Obito survived temporarly because he had Black Zetsu sustaining his life force, and subsequently Naruto's Yin–Yang Release allowed the Uchiha to live even without Black Zetsu, but the two Hokage wannabes knew that it would work only for a bit.
