Arthur Morgan is the main protagonist in the video game Red Dead Redemption 2. He is a member of the Van der Linde gang, a group of outlaws on the run in the late 1800s. Arthur is a skilled gunman, tracker, and survivalist, but he also has a conscience and a sense of honor that often sets him apart from his fellow gang members.
Throughout the game, Arthur struggles with his loyalty to the gang, his own sense of right and wrong, and his declining health. As he discovers more about the world outside the gang and forms relationships with other characters, Arthur begins to question the morality of the gang's actions and his own role in them.
As the story progresses, Arthur becomes increasingly disillusioned with the gang's leader, Dutch, and his erratic behavior. He ultimately chooses to help those who have been wronged by the gang, even if it means going against Dutch and risking his own life. In the end, Arthur succumbs to his illness but leaves a lasting impact on those around him and on the player.
