**SPOILERS ALERT**
Bucky Barnes is Steve Rogers best friend. In first Captain America he fell off a train and Steve couldn't help him. Everyone thought that he was dead.
Then in Captain America 2: The Winter Soldier, it became clear that he was in ice just like Steve Rogers. So both were young after 70 years. But Bucky was brainwashed by Hydra and was sent to kill Steve. So basically he beame an assassin and killed people. But it's all because that he was brainwashed and didn't know what he was doing.
And in a scene where he removed his mask and Steve said, "Bucky?", he couldn't even remember his own name and just responsed with, "Who the hell is Bucky?" but you can see his face was kinda lost and he slightly remembered unclear stuff, but still tried to kill Steve. Because what he remembered was nothing than maybe he saw Steve somwhere else. He then told this guy, Alexander who was matermind leading Hydra that he saw that man (Steve) somewhere. So they kept brainwashing him.. ;-;
