Arthur Morgan is a cold, brooding outlaw who often resorts to violence and has very few qualms about killing.  He isn't above joking or employing sarcasm with his friends. Despite his ability to commit great acts of violence Arthur has his own moral code and doesn't believe in what he deems as unnecessary killing, especially if it endangers himself or those he cares about.  Arthur cannot be bought, bullied or intimidated, regardless of an antagonist's size, strength, wealth or power.
