We are the sin eaters. It means that we take the moral excrement we find in this equation and we bury it down deep inside of us, so that the rest of our case can stay pure. That is the job. We are morally indefensible, and absolutely necessary.
~ Byers' philosophy

USAF Brig. Gen. Eric Byer is the main antagonist in the 2012 movie The Bourne Legacy.

He was portrayed by Edward Norton, who also portrayed Aaron Stampler in Primal Fear (1996)Steve Frazelli  in The Italian Job (2003), Nova in Alita: Battle Angel (2019) and Derek Vinyard in American History X.


Byer is a part of the National Research-Essay group and a former USAF Brigadier General. All of his actions have to do with brainwashing and causing murder. Byer discovered damaging content, which led Treadstone and Outcome agents to meet in public. Byer decided to kill all Outcome agents to prevent Treadstone from discovering Outcome's top-secret technological genetic advances. He tried to use a drone to kill Aaron Cross, the protagonist, and Number 3. However, a wolf uses it. He genetically brainwashed Dr. Donald Foite into killing all of his clients and then himself. However, there was one person, named Dr. Marta Sheering, that survives. However, Byer sends officials to murder her, but Aaron Cross saves her. Eventually, he sends LARX-3, a chemically engineered soldier, to kill them. However, even this fails when Marta Shearing kills LARX-3 by crashing his motorcycle.


  • Outcome, the program Byer heads, is jeopardized by Jason Bourne, even though Bourne never physically appears in the movie. Norton and Damon co-starred in Rounders.
  • In the scene where Eric Byer learns that the "Outcome" who survived the cabin drone attack was Aaron Cross, and recognizes the name without surprise. This is because Byer was Aaron's Commanding Officer in Iraq in 2003 and was the one who recruited him for the Blackbriar Project which explains the scene of his "death" shown on the Fallen Heroes website he shows to Weisz. The Blu-ray and DVD feature these scenes that were cut out of the film.
  • Edward Norton and Jeremy Renner have both played MCU heroes.
  • Edward Norton previously worked with Stacy Keach in American History X.
