The most humorous part of the Sokovia Accords is that the UN decided that the best man to enforce rhem was General Thaddeus "Thunderbolt" Ross. The man who ran a super soldier program that lead to failure after failure until one of the experiments went goddamned rogue (Bruce Banner aka the Hulk). Then became so obsessed with tracking him down that he ran a black budget (assumedly, right? Like it had to be) military operation that cost the US military a shit ton of money, and created ANOTHER super soldier monster. This one being a sociopathic British Special Forces obsessed with killing the first rogue experiment. So now he's made two Hulks, spent a shit ton of government money on not only multiple "failed" super soldier projects, but also domestic and international incidents — one of which to quote Dr Banner "broke Harlem" — and required SHIELD to clean it up! They were the ones who had to imprison Blonsky and they tracked Banner the whole time.
Like this is the fucking guy?!
Huh?
Someone kill my moms, I'm blacking out just like Iron Man... the fuck?
and Steve knew the entire time!
Fuck that shit. It's easy to understand Tony's motivation from the accords to Bucky
We actually don't know what Steve knew. We know that Steve was aware of Hydra's involvement in several major world events, including key assassinations, which included Howard and Maria Stark's car crash as appeared as one of the headlines shown during Arnim Zola's monologue in The Winter Soldier. Steve knew Bucky was a brainwashed assassin for them, but he also knew that they had the whole of SHIELD, plus god knows how many government officials. The whole world did. They could've used anyone.
In that movie, by Endgame the same directors were outright saying Tony had the long term view correct vs Cap's correct one movie reasoning
But the problem is that viewpoint isn't expressed in Civil War, and that's where it's important. Tony's arc over rhe course of the MCU is learning about setting aside his ego and essentially preparing the future for a better world. He's becoming the true futurist, and part of that is raising the next generation of heroes and bright minds that will also shape the world. Pepper finally says in Endgame "we got this" as he dies.
The thing is, Iron Man 3 and Age of Ultron are road blocks to this. His hubris and paranoia cause him to go too far. He wants to end the conflict before it starts and be prepared for every situation, but you can't be. Tony operates out of guilt in Civil War and believes he needs to be held responsible for his mistakes. In Endgame he plays the "this is why I wanted to create a system" or whatever, but that's not what got presented. That's not the Tony that was shown. We got a guilt-ridden Tony who wanted someone to hold him accountable so he doesn't go too far while he tries to keep doing what he's doing. So his hubris doesn't get in the way again.
A government funded bottle, which Cap wasn't exactly comfortable with. He proved himself as a hero and got touted around as a gimmick for months until he got sent to the frontlines, then he sacrificed himself only to come back and find the weapon that killed so many and he "died" for is being used by his own government.
Yeah Cap knows big organizations and governments are largely bullshit.
