So far, at least for me his reasons are not all reasonable ( reasons for killing people are never really reasonable but still ) if you weight it against what he has doen and how many he has killed.
Surely, next week we will learn about Yahiko's death then. It's not a horribly bad chapter, it does give a bit more justification. I agree it's not all that reasonable but when you are starving, living in a war-zone and something even marginally worse happens, you can snap. Most likely Yahiko's death pulled the plug on any sort of mental stability Nagato had.. I mean even Konan says in the chapter before the Invasion "can't you stop this madness?" and he says "this is my justice." It's making Nagato's character marginally better but he still needs some more bad incidents to be believable.
