Trust me, I had the same reservations. It's something Pokemon actually take part in regardless of human intervention. They appear to treat it much like a sport or competition amongst themselves.

They are far smarter than the animals back home. Many seem to be able to fully understand human speech.

I realize that, but I enjoy looking after everyone. Once everyone left after the war, despite having nothing but busy days, I felt bereft. My calling is to watch over you.
