These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Magnificent Bastard - *Napoleon, who goes by "Leo Bone, Royal Navy of Great Britain" and later "Napoleon Bonaparte, Prime Minister (and de facto ruler) of the Kingdom of France".
Also John-Spencer Churchill, who rallies Britain to repel the French invasion, then invades France right back, then proceeds to rebuild Britain whilst ruling it like a dictator. Frequently compared in-story to Napoleon, and vice-versa.
Moral Event Horizon - Lascelles galloped right over it. It is possible to cheer when he gets eaten. On the other hand, its possible to think Hiedler crossed it when he started eating people (possibly). And of cours there's the bit where Steampunk-Revolutionary-French-from-Hell-on-Crack troops not only turn Rome into a burning bloodbath of rape and pillage, but also quite deliberately murder the Pope.
This Is Your Premise on Drugs - The alternate French Revolution. "Steampunk Revolutionary France from Hell on Crack" has recently been admitted to AH.com's pantheon of arch-villains.
