Query: This is really sick book

This book gets away with its machismo and inhumaneness by being placed in a "cultural diversity-old world charm" perspective. The theme of "boys will be boys" is presented as integral to family humor, "male bonding," and a cute old grandfather."Tom" is unfit for children. It teaches that it's cool to be cruel without any comparable teaching about what animal slaughter truly entails or how the girls feel being taunted by twisted little boys. At the end grandfather and grandson are "wink[ing]" and "think[ing] of something else to do."
