Arthur Morgan was employed as a bounty hunter to locate you because you were the most wanted criminal due to the sizeable amount of money you stole from banks. He was in awe of your skills, but he still needed the money, so he took the job because he needed the money. However, when Arthur discovered you, you had been seriously hurt by some outlaws. Rather than putting you to death, the cowboy rode his horse back to his camp so he could attend to your wounds.
