The Avengers bloody rampages

If she's too inexperienced and acts without thinking, then she shouldn't have been out in the field. That's just bad decision-making by the team leader and that bad decision-making cost many civilians their lives.

And that's what the Accords were for. To prevent bad decision-making by the Avengers, resulting in inexperienced Avengers being out in the field and acting without thinking, causing the deaths of many civilians. But Steve Rogers didn't want to sign the Accords because Steve Rogers wanted to be a tyrant with no oversight and no limitation on his power and authority.

Because that's how heroes are supposed to be. People don't want to read about ordinary people doing ordinary things. People want to read about extraordinary heroes doing extraordinary things. That's why throughout history, the greatest heroes have been not ordinary people but great figures who have been head and shoulders above ordinary people, from Hercules and Perseus in ancient times to King Arthur and the Knights of the Round Table in medieval times to Superman, Batman, and Wonder Woman in modern times.

That's also why people watch professional sports. Nobody wants to watch a playground basketball game with ordinary people playing. People want to watch an NBA game with the best players, like Michael Jordan or LeBron James.

And that's also why perfection is idolized and revered in sports. When a pitcher pitches a perfect game, it's celebrated as an epic achievement. The 17-0 perfect season by the 1972 Dolphins is still revered as the greatest season in NFL history because they achieved perfection. Michael Jordan, who was a perfect in the NBA Finals, is considered by most people to be the greatest basketball player ever. And Joe Montana, who was a perfect in Super Bowls and never even threw an interception in a Super Bowl, is considered the greatest QB in NFL history.
