This artical tells about a man who lived in a NK labor camp. You get punished for not reporting others missdeeds, so when his mother and brother tried to escape, he turned them in and watch them get executed.
He then escaped by climbing over his electrocuted co-worker as he lie on an electric fence.
Read the story, you will like it 
It is an enviroment that would instill a competitive adversarial relationship between all inmates, and even the guards at that. So I think you're onto something. Perhaps some aspects of ASPD are conditioned, rather than really always hardwired? I wonder if its possible to ever move beyond that, he says that sometimes, he still feels like he's back in the labor camp, like its not over. Reminds me of PTSD.
