The question you asked seems to be more speculative and poetic rather than something that can be objectively answered.
London, like any city or community, has a complex history with moments of both triumph and tragedy. Throughout history, cities have experienced various events that have brought both joy and sorrow to their inhabitants. The emotions of a city, like London, are reflections of the emotions of the people who live there and the events that unfold.
It's important to recognize that cities, being composed of diverse populations, experience a wide range of emotions collectively. Whether a city "cries for its atrocities or sorrow" is a matter of interpretation and can vary depending on the perspective and the specific events and circumstances involved.
As we move into the future, it is essential to learn from history, acknowledge both the positive and negative aspects of our past, and work towards creating a more inclusive, compassionate, and understanding society for everyone.
