Kurt Vonnegut Jr. has a lot to say about Massacres. He witnessed the firebombing of Dresden in World War II. His novel Slaughterhouse Five is based on it and his experiences since.
It is so short and jumbled, Sam, because there is nothing intelligent to say about a massacre. Everybody is supposed to be dead, to never say anything or want anything ever again. Everything is supposed to be quiet after a massacre, and it always is, except for the birds.

And what do the birds say? All there is to say about a massacre, things like "Poo-tee-weet?"

I have told my sons not under any circumstances to take part in massacres, and that the news of massacres of enemies is not to fill them with satisfaction or glee.

I have also told them not to work in companies that make massacre machinery, and to express contempt for people who think we need machinery like that.
