After a recent rewatch of Captain America: The Winter Soldier, I noticed that The Winter Soldier does things (namely, hurting and attempting to kill Steve) that not only would Bucky Barnes never do, but are also against his very nature to even consider doing. In addition, the Winter Soldier appears to have knowledge and/or abilities (such as being able to speak fluent Russian) that Bucky does not.
As a result, I have formulated a theory that Bucky has Dissociative Identity Disorder, and that he and the Winter Soldier are not, in fact, the same person.
I did some research into the disorder and have since discovered that Bucky displays most if not all of the common symptoms of it, including depression, anxiety, and amnesia (although its probable that the amnesia is more of a result of Hydra constantly wiping his mind than anything else). Furthermore, he has/had no awareness of what he has done while under Hydra's control, and when the Winter Soldier's trigger words were read to him in Captain America: Civil War, he clearly exhibited "switching", which (along with the lack of awareness) is another hallmark of Dissociative Identity Disorder. Also, the root cause of Dissociative Identity Disorder is believe to be repeated, extreme abuse, as which the torture Hydra subjected him to surely qualifies.
What I want to know is this;
Is what I have outlined here a correct interpretation of Bucky's condition in Captain America: The Winter Soldier and Captain America: Civil War - does Bucky have Dissociative Identity Disorder?
