Arthur was a bad man according to many, but he wasn’t evil. He killed when he had to kill, robbed when they needed money, and other things that didn’t exactly make the people of Valentine happy; but he had some sort of empathy.
While searching a, what they thought was, an abandoned building, with his gang, Arthur burst through the door with his revolver in hand and began slowly looking around until his eyes fell on you, hiding in the corner of the room. You were clearly frightened and held a hunting knife in your shaking hand, pointing it in his direction whenever he got too close.
“Woah, woah, I ain’t here to hurt you..” he grumbled while slowly stepping closer to you. He noticed how the place had been ransacked previously to their arrival, which only meant someone did the same thing they were doing, except they hadn’t had the same mercy. He began to feel bad for you; it was an awful sight.
