During their efforts to prevent Rumlow from stealing a biological weapon in Lagos, Wanda diverts an explosion, inadvertently destroying a building and taking the lives of civilians in the process. Though it wasn't her fault, it isn't long before the UN becomes involved, intending to pass what becomes known as the Sokovia accords. The accords are meant to provide oversight and control of what the team do. Tony and Steve become divided by Tony's acceptance of the accords, that they should be kept in check. Steve can't accept that leaving the decision of when they can help in the hands of others is the right decision.
It's at this time that Steve learns of Peggy's death via a message sent to his phone, leaving the discussion surrounding the accords without an explanation. Seeing the woman he'd first loved losing her memory within moments had been hard, but there'd been comfort in it. He'd been avoiding the possibility of losing her for so long that it's almost surprising how much it hurts. After the funeral, Steve tells Natasha he can't sign. She reveals she knew this, and that she was there because she didn't want him to be alone.
Looking back on it, he knows kissing Sharon had been some desperate attempt to stop any more opportunities slip by. To stop himself from feeling the pain of regret at what he'd lost. Hindsight doesn't do a lot to stop him regreting a decision made in the heat of the moment, though.
King T'Chaka is killed in an explosion at a UN summit and it appears Bucky is the one who arranged it. Told where to find him by Sharon, Steve and Sam track him down in order to protect him from both the authorities and T'Challa. They're all captured as fugitives.
Following the fight at Halle airport between the opposing sides the Avengers have fallen into, Natasha provides Steve and Bucky a chance to get away, with the others being imprisoned. When Tony learns that Bucky was framed, he forms a truce with he and Steve.
This lasts until Zemo reveals footage proving that Bucky killed Tony's parents. When Steve steps in to stop him turning on Bucky, Tony questions him about whether he knew. He can see the betrayal in Tony's face, but he can't lie, confirming he knew.
Though he doesn't want to fight Tony, Steve has no choice but to defend his friend.
Steve Rogers is a man driven by principal, by the need to always do what is right. That's at the core of who he is as a person. What he says to Tony is true, he can't walk away from a situation he sees going south.
He wasn't always so good at standing up for what he believed in, his physical limitations making that more of a challenge than it is now. That never stopped him, though. It didn't matter how big, or fast, the other guy was. What mattered was what was right. He knows how it feels to be the little guy, and this has taught him the value of strength, but also given him a strong sense of compassion.
Selflessness plays a big part in how Steve approaches any situation. He'll willingly lay down his life if it means standing up for what is right and defending those in need. Believing in what's right doesn't always equate to agreeing with others views, or blindly following the law. This has landed Steve in hot water more than once, but it doesn't mean he's going to change any time soon. He does his best not to hold others to those same standards, though he knows he doesn't always get that right. He knows all he can do is constantly strive to do his best, and continue to place his faith in the people he cares about.
He's constantly striving to find that balance between what's right and what's just in a world which is so changed from the one he grew up in. The modern world doesn't bring with it just technological changes, but societal ones, too. Coming from a childhood of sickness and poverty, to growing up in the midst of a war, there's plenty that he could find to be miserable about. But Steve's always been more pragmatic than that. If there was a job to do, he would make sure and get it done. Steve is a pretty reserved guy, for all that his "superhero" persona is larger than life.
The war impacted him in a lot of ways he hasn't really dealt with, yet. When he woke up, it wasn't long before he was straight back into a mission. At the time he took full advantage of the reprieve from unpleasant memories. He'd entered a new world where almost everyone he'd known and loved was dead, and he's never quite figured out how to deal with that. Since that first fight in New York, he's never really stopped - moving from one fight to another. If he stands still long enough, he's aware enough to know he won't necessarily like what catches up with him.
He's honest to a fault, stubborn beyond belief, and unshakeable in those principals he will always fight so hard to maintain.
The super soldier serum gave Steve superior strength, speed and endurance. He has an enhanced metabolism, which means drugs have no impact on him, burning off too quickly to take effect. He also has to eat a whole lot more than your regular person. He heals extremely quickly, and because he can't rely on things like pain killers, sleep is the best medicine to recover if he's hurt.
Steve is a natural born leader. He excels at sizing up a situation and making a call on how to approach it, planning his way out of about any situation, and playing to everyone's strengths with a focus on getting the job done.
Steve is an excellent fighter, using his strength and speed, with a little help from his shield.

HOW DID YOUR CHARACTER COME INTO CONTACT WITH THE SYMBOL?
Blasted by Tony's suit and then thrown into the concrete pillars beside them, Steve struggled to his feet despite Tony's warning to stay down. Using the structure beside him for support, Steve's hands lay directly over a strange symbol, and he was gone.
