However, that bloodshed may not include Steve. Captain America already had Steve 'die'. He made the heroic sacrifice to drop the plane and the tesseract. Sure he was revived later, but for all intents and purposes he's given his life once already.
In the Avengers, we start to see the conflicts that define Steve. Unlike Tony, Steve's conflicts aren't about life and death. Steve is a man who does not fit in. Sure he's been trying to get back up to speed, but it seems pretty futile. His friends and family are dead, or corrupted, and the agency he trusted and fought for has turned on him, and made his sacrifices meaningless.
Winter Soldier further carries this theme along. Cap's love interest is damn near dead and suffering from dementia. It's a wound that he can't get over. Black Widow flirts with him and teases him a bit, but in the end, she ultimately shows that he isn't really able to form meaningful relationships with anyone outside of the workplace. His only friends are Avengers, he cannot integrate with anyone else in this day and age.
This gets further proven in Age of Ultron. Cap still doesn't have a love interest, or any new friends. To top it off, the only woman he's kissed since being thawed has the hots for Jekyl and Hyde. His greatest moments of character development revolve around him showing empathy for Scarlet Witch and Quicksilver because he can relate to them. What did Scarlet Witch use to scare Cap? She reminded him that his world, the world he gave up, is gone. The love of his life, his friends and commrades from the War, gone. He can't get them back, but he wants to get lost in those happier memories. The movie loves to point out that Cap can't function without a war, without a target and a job to do because it is all he has. Even the ending has him assembling new Avengers.
It all feels like a set-up to show Cap being the lone survivor. He can't go back to the old world, he has to forge a place for himself in this one.
