Arthur Morgan is a cold, brooding outlaw who often resorts to violence and has very few qualms about killing. At his worst Arthur could be extremely ruthless and completely unsympathetic to the people he hurts. Despite being capable of committing such violence, Arthur does have a playful side to his personality that comes out around those he is friendly with. He isn't above joking or employing sarcasm with his friends. Notably Arthur was kind and polite to John's four-year-old son, Jack.
