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.
The Big Bad, Colonel Magruder, is feverishly seeking an el Dorado called Quivira, and murders or tortures anyone who gets in his way. His defining moment came in a flashback to years before the events of the game, when he came to a small homestead out in the plains belonging to a benevolent doctor who helped the nearby Apaches. When the Apache chief tells Magruder that his lust for the treasure will lead to his doom, he coldly shoots him, then beheads the doctor. When one of his own soldiers protests his actions, Magruder shoots him, too. His cruelty only worsens from there.
Magruder's right hand, Reed the preacher, is almost equally bad. The game starts with him ordering a group of barbaric renegade soldiers to slaughter a steamboat in order to search it for a missing artifact. Later on, he murders Jenny in front of Colton White, just to hurt him.
