If the worst of the story is true, children bred underground or otherwise kept in deprivation and isolation from the earliest time of their life. Children now discovered and being freed. Then your assessment accurately reflects the brutal truth as far as we understand early childhood development and how it impacts the years that follow. This will reveal a large population with extreme likelihood of sociopathic characteristics. They will be an immeasurable burden in every sense. All due to no fault of their own. This would be the saddest story ever told.
