[Ratatouille] How come Anton Ego reputation remain intact after Gusteau's death?
gpt
That wouldn't lessen Ego's reputation; it'd inflate it.

Ego isn't renowned for his kind and gentle words, praising and encouraging rising stars in the culinary world. He essentially rules by fear, combining an incredibly refined palette with a cruel but clever writing style; the persona of the vicious critic is half of why he's so well-known. It's his gimmick.

Gusteau's death would've just added to the legend of Ego; especially if he was as callous and unsympathetic after the death as he is with everything else. Imagine a scenario where someone asks Ego if, in the light of Gusteau's death, he intended on revisiting his review of the restaurant, only for Ego to answer something like "Why? Did the food improve?". 

Sure, people would say Ego was an asshole, and very few people in the industry probably have anything nice to say about him when they know he isn't listening, but regardless, it builds a reputation.
