The questions I have about Neglected World Jumper are about how Naruto's neglect came about and why it happened. There doesn't seem to be any actual reason or purpose for it. It would be one thing if Naruto was neglected over Jiraiya's prophecy (though most authors fail to execute that well), but from what we've seen in this story, Jiraiya had nothing to do with Naruto's abuse, and certainly doesn't seem to approve of the neglect Naruto suffered if he knows about it.
So what exactly is the reason for Naruto's neglect by his parents? Why did Minato essentially leave him to die when Madara kidnapped him? Why did Kushina abuse him so harshly? And why was Minato amused at the pain that Naruto suffered? Why did he allow it to happen? What are Minato's and Kushina's personal reasons and motives for doing what they did to him, and allowing him to suffer at the hands of the villagers? They wouldn't put forth the level of effort that they did into abusing him without a reason or a motive - what would be the point of wasting the energy to do that when that energy could be more productively spent doing something else?
