After the factory, he seams unwilling to eat them.
Actually, it seems he's rather apathetic to the whole thing. It seems that he doesn't care or notice the yukkuris' suffering; he doesn't want the yukkuri treat he got from the trip because it's bad or something.
Apathetic yes, but we do not know how he felt before he went to the factory as all the images of said factory are flashbacks.
If he's apathetic during and after it his attitude before it wouldn't be different. Of course, that doesn't matter because he's more concerned with how the actual product is (it's gone bad) rather than his feelings about the process.
