You don't understand the concept of a a "strawman" if you think me speculating that your knee-jerk rage at anything Disney is perhaps based on a dislike of Disney itself. Alternate theory-- you're treating our discussion as a debate or argument, when I'm having a friendly back and forth to share our thoughts about the show.
Sam and Bucky represent the U.S., so declaring the U.S. to be the villain makes no sense. Apparently, to you, the U.S. is both hero and villain? If you feel that way, you're onto something, but it isn't a hero-villain dichotomy. This show is VERY good at pointing out nuances of opinion and behavior, and it can be easy to look at only the surface level and declare someone, or something, good or bad. But the villain is not the U.S., and I see zero reason anyone would think that. The Flag Smashers have clearly, definitively, and inarguably been painted as the villains from the get-go.
Your final paragraph doesn't make a lot of sense. My belief is that in a world with superheroes, the heroes do need to be held accountable, but not with anything as extreme as the Sokovia Accords from the Civil War film. That's an entirely different discussion than anything in this show.
Bucky and Sam didn't exactly break Zemo out, but they were instrumental in encouraging him to escape, but even if we dismiss that nuance, I don't see it as anywhere near as big a deal as you do. A very common trope in comic books, or hero stories in general, is one in which the hero uses unconventional, and often illegal, methods in order to do the right thing. Sometimes, the ends justify the means. So temporarily freeing a criminal in order to capture a band of criminals and save thousands, perhaps tens of thousands, of lives, before returning that criminal to prison, is, in my mind, a completely justifiable trade-off.
Let's put this in a real world context. Imagine that a week before 9/11 you knew something was coming, but not what. All you knew was that Ramzi Yousef, the guy who bombed the World Trade Center in the ‘90s, could lead you to the terrorists who were planning something, and he had some grudge against them, so you knew he’d help you. If you had the means to illegally free him long enough to lead you to Osama bin Laden in time to prevent 9/11, after which you’d deliver him back to his cell, would you do it? Does saving the lives of 2,977 people justify busting him out for a couple days? I’d do it. Would you?
As for Walker— of course he should be held accountable for murdering someone. So should Sam, Bucky, or anyone who oversteps their boundaries like that. If Bucky had shot and killed Zemo, I’d hope the Wakandans would be delivering him to the raft instead of the Baron.

Are you talking to yourself? Because I said I didn't like one Disney show and your reply was that I have "a strong Disney bias." That's literally a Strawman, bud.
