Thunderbolt Ross: Huh. Five years ago, I had a heart attack. I dropped right in the middle of my backswing. Turned out it was the best round of my life because after thirteen hours of surgery and a triple bypass, I have found something forty years in the army had never taught me... perspective. The world owes the Avengers an unpayable debt. You have fought for us, protected us, risked your lives. But while a great many people see you as heroes, there are some who would prefer the word "vigilantes".
Natasha Romanoff: And what word would you use, Mr. Secretary?
Thunderbolt Ross: How about "dangerous"? What would you call a group of US based, enhanced individuals who routinely ignore sovereign borders and inflict their will wherever they choose and who, frankly, seem unconcerned with what they leave behind? New York, Washington D.C., Sokovia, Lagos...
Steve Rogers: Okay. That's enough.
Thunderbolt Ross: In the past four years, you've operated with unlimited power and no supervision. That's an arrangement the governments of the world can no longer tolerate.

Tony: We need to be put in check. And whatever form that takes, I'm game. If we can't accept limitations, if we're boundary-less, then we're no better than the bad guys.
Steve: Tony, if somebody dies on your watch, you don't give up.
Tony: Who says we're giving up?
Steve: We are if we're not taking responsibility for our actions. This document just shifts the blame.
Rhodey: Sorry, Steve, that — that is dangerously arrogant. This is the United Nations we're talking about. It's not the World Security Council, it's not S.H.I.E.L.D., it's not HYDRA....
Steve: No, but it's run by people with agendas, and agendas change.
Tony: That's good! That's why I'm here! When I realized what my weapons were capable of in the wrong hands, I shut it down. Stopped manufacturing.
Steve: Tony, you chose to do that. If we sign this, we surrender our right to choose. What if this panel sends us somewhere we don't want to go? What if there's somewhere we need to go, and they don't let us? We may not be perfect, but the safest hands are still our own.
Tony: If we don't do this now, it's going to be done to us later. That's the fact. That won't be pretty.
"Compromise where you can. Where you can't, don't. Even if everyone is telling you that something wrong is something right. Even if the whole world is telling you to move, it is your duty to plant yourself like a tree, look them in the eye, and say, 'No, you move.'"
— Sharon Carter quoting Peggy Carter (quoting Cap from the original comic)
"The Black Panther has been the protector of Wakanda for generations. A mantle passed from warrior to warrior. And now because your friend murdered my father, I also wear the mantle of king. So I ask you, as both warrior and king, how long do you think you can keep your friend safe from me?"

Steve: If I see a situation pointed south, I can't ignore it. Sometimes I wish I could.
Tony: No, you don't.
Steve: ...No, I don't.

Vision: [straining] If you do this, they will never stop being afraid of you.
Wanda Maximoff: I can't control their fear. Only my own.
Captain America: Did Stark tell you anything else?
Spider-Man: That you're wrong. You think you're right. Makes you dangerous.
Captain America: [kicks him into a gangway] Guess he's got a point.
Captain America: You got heart, kid. Where are you from?
Spider-Man: [straining] Queens!
Captain America: ...Brooklyn.

Tony: Did you know?
Steve: I didn't know it was him.
Tony: Don't bullshit me, Rogers, did you know?
Steve:...Yes.
Steve: I didn't know it was him.
Tony: Don't bullshit me, Rogers, did you know?
Steve:...Yes.

T'Challa: Is this all you wanted? To see them rip each other apart?
Zemo: My father lived outside the city, and I thought we would be safe there. My son was excited. He could see the Iron Man from the car window. I told my wife, "Don't worry. They're fighting in the city. We're miles from harm." And the dust cleared, and the screaming stopped. It took me two days until I found their bodies. My father still holding my wife and son in his arms... And the Avengers? They went home. I knew I couldn't kill them. More powerful men than me have tried. But if I could get them to kill each other... I'm sorry about your father. He seemed a good man, with a dutiful son.
T'Challa: Vengeance has consumed you. It's consuming them. I am done letting it consume me. [retracts his claws] Justice will come soon enough.
Zemo: Tell that to the dead.
[points gun to head, T'Challa stops him]
T'Challa: The living are not done with you yet.
Iron Man: [points one of his blasters at Captain America] Stay down... final warning.
"That shield doesn't belong to you. You don't deserve it! My father made that shield!"

"Tony, I'm glad you're back at the compound. I don't like the idea of you rattling around a mansion by yourself. We all need family. The Avengers are yours, maybe more so than mine. I've been on my own since I was 18. I never really fit in anywhere, even in the army. My faith's in people, I guess. Individuals. And I'm happy to say that, for the most part, they haven't let me down. Which is why I can't let them down either. Locks can be replaced, but maybe they shouldn't. I know I hurt you, Tony. I guess I thought by not telling you about your parents I was sparing you, but I can see now that I was really sparing myself, and I'm sorry. Hopefully one day you can understand. I wish we agreed on the Accords, I really do. I know you're doing what you believe in, and that's all any of us can do. That's all any of us should... So no matter what, I promise you, if you need us - if you need me - I'll be there."
— Steve Rogers
