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: Again, Silva. He has a habit of dealing out a ridiculously appropriate (and often over the top) lesson and/or punishment to anyone he thinks needs one. For example: one sailor is mocking the coxswain who has become terrified of the sea since arriving in the new world (for very good reason, and the coxswain continues to do his job despite being humiliated by his own fear). Silva's response? To pull the pin on the chain the mocking sailor was leaning against, leaving him to go tumbling over the side and only save himself by grabbing the chain. Afterward, he's afraid of the water.
His "prank" on Chack (a Lemurian who joins the Americans on Walker): Silva proclaims Chack's sister to be his wife...and she goes along with it! Poor Chack was this close to murdering Silva when that happened.
That racist asshole who raped a 'Cat in book two. Walker's other enlisted men lynch him for it.
Walter Billingsley wades into this territory when he abducts Rebecca, Sandra, Sister Audrey, Silva, and Lawrence and blows up the dock's fuel reserves, killing 17 people. He steps up a notch by ordering the captain of the Ajax to fire upon two Lemurian ships because the female Lemurian captain of the frigate dared to speak to him and concocts a plan to "dispose" of all hostages but Rebecca and have the captain and the men loyal to him executed by a Kangaroo Court for "firing upon a defenseless ship". His death comes courtesy of Silva setting Ajax's powder magazine up to explode.
