How does the morgue in Guatemala City serve as a wakeup call for Frank as noted in the memoir, Monkey Boy?

The basement morgue in Guatemala City that the nurse takes Frank to visit after a cocktail party symbolizes the brutality of Guatemala’s civil war and the lengths its government took to conceal the reality of its campaign of genocide. The morgue then is a wakeup call for Frank. The obscenity of the mangled bodies stacked in the morgue symbolizes not just the violence of the internecine war in Guatemala but in all such civil wars conducted between oppressive authoritarian governments and advocates of human and civil rights. Frank has been covering the war in his magazine articles, but until Ursula escorts him to the dark basement of the hospital where she works Frank has never actually looked into the dark heart of the war and the human toll of a government fighting its own people, a military government bent on silencing opposition viewpoints through arrests, torture, and murder.
