Those are 2 little sociopaths, with no empathy toward others. Their baby mama and sperm donor should be sent to the nearest vet to be neutered and spayed so they don't have an opportunity to shoot out any more monsters like these 2.
Seriously, these "kids" are into the second stage of sociopathy. The authorities or some serious adults should look into the immediate neighborhood and determine the incidence of abused, injured or mutilated pet killings.
Clearly this is a government housing neighborhood. I can't imagine any normal family living among these feral little animals by choice.
