He meant human heroes killing many human villains. They very purposely didn’t do it much after A New Hope. It became mainly faceless and non human characters in the later films.
No, he didn’t. As I quoted George again in my post:
George Lucas: Yeah, we very consciously didn’t kill very many humans in those movies.
The facts in the “movies” (plural) themselves prove they also did do this after Star Wars (1977).
George forgets the title of his films are “Star Wars”, and also the more bloodshed content in them.
He wants to play down some of the violence in them as he aged, had a family, and maybe wants to leave a moral legacy behind.
Looking for justifications for his retcons and false claims is not new to him.
I will not derail your thread further as this is about the many differing and changing incarnations of his Sequel Trilogy, including the times George said they did not exist and never existed, other than his previous vague claims and ideas.
