BBC:s Olenka Frenkiel intervjuar Kwon Hyok, en avhoppad agent som berättar om gaskamrar i den nordkoreanska Gulag-arkipelagen:
”’How did you feel when you saw the children die?’, I asked.
His answer shocked me.
‘I had no sympathy at all because I was taught to think that they were all enemies of our country and that all our country’s problems were their fault. So I felt they deserved to die.’”
