@yaypie Does your game have any notes on the root cause of this behavior?
The root cause tends to be that someone wants to steal my horse and that I do not want them to steal my horse.
Having reached an impasse of wills, the offending party typically proceeds to steal the horse, whereupon I employ bullets to remove them from said horse. Inevitably a stray round discommodes a hat or a noggin or some lesser extremity of a passerby, at which point the passerby (or an avenging party thereof) enters the fray and things get, for lack of a better word, medieval.
I'm not sure there's much to be learned from the game about human nature, except inasmuch as it is apparently human nature for disagreements about horses to have violent consequences.
