You are right about that. I would add that non-human lives are also valuable. I especially believe animal suffering is terrible, ours and others. We are enough to help humankind and also repair injustices to and help other beings.
What I wanted to comment is that I felt this image intensely because it is kind of symbolic. It represents the beauty we are capable of, the way we can be brought together by beliefs and dreams, all destroyed by greediness, selfishness, and unnecessary violence. It is tragic. It is not the value of the building itself, which is debatable, but this I explained.
