The Winter Soldier's character development through time travel is complex. He might travel back to a time when he was still Bucky Barnes, before all the trauma. This encounter with his former self could stir up memories and emotions that he had long buried. As he moves through different times, he could learn new values and ways of thinking. For example, in a more technologically advanced future, he could learn about new forms of therapy that help him deal with his past. Time travel also gives him the opportunity to see how the world has changed because of his actions, both good and bad, which can shape his future self.
Time travel is a great device for the Winter Soldier's character development. Firstly, it allows him to break free from the cycle of being a weapon. When he travels, he can meet people who see him not as the Winter Soldier but as Bucky Barnes. This can boost his self - esteem. Secondly, seeing different historical events can give him a broader perspective on life. He may realize that there are more important things than just following orders. Thirdly, time travel can introduce him to new allies or enemies. Interacting with them can teach him about trust and betrayal, further shaping his character.
