Uhmm, he wanted to create peace in the ninja world and it was something he couldn´t do in his life-time alone, he was the jiuubi jinchuriki but he knew that he knew that the jiuubi would go free when he died, he knew he was going to die, he separated the jiuubi into nine parts when he was nearing the end of his life, sure he was something of a god while still alive but when he died he was just like everyone else, human.
He wanted to bring peace and he couldn´t do in his life-time so don´t you think he would´ve continued to live if he could?
