Doesn't DPPt have a house in Sunnyshore in which they refer to him preferring machines to people/Pokemon as a kid? I would imagine that means that whatever spurred him to create a cult group and try to create another world/etc would have arised from that then as a beginning. I think his grandpa was also in Platinum in some route who wished he had helped him earlier or something...

So I guess some family-related fued might have made him think emotions was teh bads. Not much else to go on from what I recall with that though, and idk about manga/anime.
