YMMV / The Scarlet Pimpernel (1982)

• Complete Monster: Citizen Paul Chauvelin is a much more malevolent figure than his novel counterpart. As head of the Committee for Public Safety (or National Security), Chauvelin is responsible for the seizure and execution of France's aristocrats for supposedly being threats to France, often down to the last child. Tasked with arresting the Scarlet Pimpernel in exchange for a Council seat, Chauvelin frames his old flame Marguerite St. Just for ordering the deaths of another family to drive her away from her new husband Percy, then blackmails her into becoming his spy by threatening to execute her brother Armand as a spy for the Scarlet Pimpernel. Capturing the Scarlet Pimpernel—actually Percy—Chauvelin orders the executions of Percy, Marguerite, and Armand out of spite even when he offered their release before being defeated.
• Moral Event Horizon: Assuming Chauvelin isn't already on the other side of this line, he most definitely crosses it when he reneges on his promise to spare Marguerite's life after Percy has been (supposedly) executed. Thank goodness he wasn't as much in control of the situation as he assumed...
