He (Tony) really wants to murder Bucky with his own hands in this scene. That’s really the thought process we were following…
…We wanted this to be a brutal grudge match between these characters. And obviously this wasn’t the case but for the smallest fraction of a second we wanted to make you believe that the shield might go in Tony’s face. But Cap is not that kind of person. Cap is the kind of person that, no matter how much he loses control and the end of the day he is purely trying to end the fight. If you go back and look at the sequence just about everything he does, every move he makes, is to disable.

Director and writer commentary (aka directors Joe and Anothy Russo and writers Chris Markus and Stephen McFeely) regarding the final battle between Steve and Tony in Civil War.

Pretty damn sick of reading meta that paints Steve as supposedly the overly violent one in that final battle scene in Civil War. It is especially precious when such blatantly wrong meta is tagged in Steve’s tag with zero regard to basic fandom politeness and common courtesy. So here you go, concrete, empirical evidence that no, STEVE wasn’t the overly violent one in that scene.

Source (like literally you can download the director’s commentary and listen to it FOR FREE so there is no excuse to post such blatantly wrong meta, in the character tags no less, unless you’re purposely going out of your way to be an ass).

Tony was straddling Steve’s chest earlier in the fight, and he threw a punch at Steve’s head which shattered the concrete when Steve ducked aside. Yes, Tony was mad with grief. Yes, Ross had pushed him to the breaking point. Yes, Zemo poked his big red shiny candylike button to get him to go off, but at the end of the day, Steve had to fight Tony to keep him from committing cold blooded murder, and I think by the time the phone arrives, both of them realize that. They both know they’d been shoved into the worst possible place by the end there, and they both have the hindsight to be feeling stupid about having gone there, but Steve and Tony both know that Tony was teetering on an edge he couldn’t have recovered from if Steve hadn’t stopped him in Siberia.
