I am not familiar with any Berlin firebombing raids, but there may have been some. Dresden was a horrible mess. Unfortunately, it is a part of war. Hopefully, that kind of thing won't have to happen again.
The Tokyo firebombing raids killed more than the nukes on Hiroshima. Robert Morgan's biography talks about them. He flew the Memphis Belle, and after he came back for the war bonds drive, he flew B-29s in the Pacific. He said that as they flew over Tokyo, they could smell the burning bodies. I shudder to think of the horror of the firestorm.
