>>12140507I think it's more along the line that he was searching for the truth about his cause. You know, how he's always confused when he hears the player's Pokemon say that they like you. He wants to know the truth - whether Pokemon are abused for human gain or if humans and Pokemon grow together through bonds and friendship. It's the player that is pursuing the ideal world of humans working together with Pokemon.
And it also coincides with the part about the Yin Yang "there is some truth in ideals, and there is some ideal in truth" (the dots in the symbol), because while a world where humans and Pokemon work together and bond is the ideal, there are still those who use Pokemon for their own gain; conversely, while it is true that there are those who abuse Pokemon, humans and Pokemon can live together peacefully.
