How are the children on the other sid of the fence treated by the soldiers boy in the striped pajamas?

In "The Boy in the Striped Pajamas," the children on the other side of the fence, who are inmates in the concentration camp, are treated with extreme cruelty and dehumanization by the soldiers. They are subjected to harsh conditions, starvation, and violence, reflecting the broader systemic oppression of the Holocaust. The protagonist, Bruno, initially fails to understand the gravity of their situation, viewing them as mere playmates through the fence. His innocence highlights the stark contrast between his sheltered life and the brutal reality faced by the children on the other side.
