Naruto Thread (Spoilers For Sure)

Wait he said that he thought about the future more maybe he didnt win the fight so he could get some of the 1st hokages power, maybe he used all his energy to make a strong zetsu type clone of himself killing himself too, so that he could live in the future, and would the 1st hokage really kill someone? I think he would be more naruto style and beat him but left him to live cause he couldnt bring himself to kill his rival\friend like sasuke and naruto.
