describe the suffering of people which made anne upset

Anne has not seen the horrific suffering of others personally but she can imagine and sympathize. At times she holds an empathy with others that suffer while she is in hiding.

It’s utterly impossible for me to build my life on a foundation of chaos, suffering and death. I see the world being slowly transformed into a wilderness, I hear the approaching thunder that, one day, will destroy us too, I feel the suffering of millions. And yet, when I look up at the sky, I somehow feel that everything will change for the better, that this cruelty too shall end, that peace and tranquility will return once more". - July 15, 1944
