Shin was both a valued snitch (since he’d sold out his family) and the victim of other snitches—as a result, Shin seemed to accept and expect that his peers would inform on him for their own selfish benefit, and that he’d just as soon do the same for them. He continued to participate in cruelty and violence at the camp, partly because he’d been trained to do so since he was a child (and again making it confusing why he suddenly stood up for a peer earlier in this same chapter).
