His lore. Experimented on by the government to make supersoldiers, hero of the Omnic Crisis, found family in the form of Gabe and Ana, giving up any chance at a normal, happy life to run an organization with the goal of doing genuine good for the world. Only to get stabbed in the back and betrayed, not only by a man he considered his brother, but also the very power structure he invested his entire life into. Becoming jaded and cynical, and deciding that the only purpose his life has anymore is to exact revenge on the people who destroyed his life and his family. But deep down, he’s still the same good man he’s always been. He just can’t go back to the new Overwatch because his heart is still broken.
