In addition to the smooth plot and good-looking action scenes, the biggest highlight of the film is to make the character of Byrne fuller. In the first part, the reason for the failure of Bourne's mission is that the assassination target is with the child, and he can't bear to attack in front of the child, which makes Bourne a human killer. In the second part, after finding out what happened before and after his first murder mission, he visited the daughter of the deceased, apologized to her, and more importantly, erased the shadow from her heart for many years. As a result, Byrne truly became a "person", a flesh-and-blood, responsible person, rather than a killing machine.
