I’ll get this out of the way right now, I’m a progressive socialist and Kissinger’s legacy in the world is one of reactionary repression and suffering. I find pretty much everything he stood for to be wrongheaded and harmful to society.
That said, celebrating someone dying in the way that’s happening now shows disrespect to human life and an utter lack of humanity. I understand the motivation, but it should be fought against by remembering that no one is ever just one thing, everyone is a mix of good and bad, and we certainly shouldn’t give in to the desire to rejoice at another’s death, no matter what we think of them.
For my part, I agree. I don’t celebrate death. I sure as hell ain’t gonna mourn evil people, or pretend the world isn’t objectively better off without them. I’m also not gonna lose any sleep over other people doing it. I’ll happily celebrate any good things resulting from their death. But death itself isn’t to be celebrated, not for me.
