Queen Grimhilde's "Thirsty?! Have a drink!" is a Good Example as that Line makes her Pass the Baseline to be Pure Evil as it Confirms that Skeletons in her Dungeon are actual People that she Killed and Imprisoned by Starvation, Murder, etc.
Plus I Believe if that Line was Omitted In-Film, she would be a Villainous Benchmark and all the Skeletons would be Fridge Horror if they are Decorations, Real People, etc. would be Debatable
