Compared to that, his past crimes are meaningless. Interestingly, the world was in trouble because of many of his own actions. Sasuke going evil(partly Itachi), Kabuto going Evil(a little with Danzo), mastering down the reincarnation technique, that would have just stayed as it was, if he didn't try to mess with life and death before.

He kind of was brought(or revived back) back for serving those purposes. He was ready to do so, and not do so, under the words of a troubled by the world itself. Plus, he kind of reincarnated someone he himself could not control(Hashirama) and the fact that the world, along with him is gonna go forever trapped in a genjutsu, and stuff isn't pretty easy to pass away. But anyways, those weren't the reasons he did what he did, it was only for the favor of Sasuke and to see what this winds leads him to.
