What's the tragic part about Anne Frank?

The main tragedy is that an innocent young girl who was only fourteen years old, and who harmed no-one, was brutally killed by the Nazis, along with her sister and her mom. They all died in the concentration camps, where they suffered terribly, as part of Hitler's plan to destroy all the Jews in Europe. Before Anne and her family were discovered, they had lived in a secret room in Holland, which family friends provided for them. But they were betrayed and the Nazi troops found them. Only her father was able to survive; fortunately, a family friend rescued her diary, and it survived too. The other tragedy is that the Allied troops liberated the concentration camp where Anne and had been held, but sadly, the liberation came a month too late-- by the time the camp was liberated, Anne, as well as her sister and mom, had already died.
