The Avengers bloody rampages

That's why Civil War is such a huge failure as a movie. It fails to address the consequences of a super-powered beings acting on their own without any supervision or any accountability for their actions.

That's why BvS is a much better movie than Civil War. Because BvS does bring up those questions:
"To have an individual engaging in these state-level interventions should give us all pause."
"I'm not saying he shouldn't act. I'm saying he shouldn't act unilaterally."
"In a democracy, good is a conversation, not a unilateral decision."
"How far will he take his power? Does he act by our will or by his own?"

These questions bring up 2 important points, that MCU fans who defend Cap's tyrannical behavior fail to understand:

1. The Accords isn't saying the Avengers shouldn't take action. The Accords is only saying the Avengers shouldn't take action unilaterally.

Think back to the Cuban missile crisis. Soviet ships are transporting nuclear missiles to Cuba. American ships have formed a blockade around Cuba. The whole world is watching anxiously to see if a nuclear war might be started. Fortunately, the Kremlin ordered their ships to turn around and no shots were fired by either side.

But imagine if 1 of the Soviet ship captains had unilaterally decided that he was going through the blockade and nothing would stop him. Or imagine if 1 of the American ship captains had unilaterally decided that he was going to fire first. That is why there is oversight and supervision and a clear command structure. So that nobody makes a unilateral decision that results in massive unwanted consequences.

But Cap didn't want any oversight or supervision because he wants to be a tyrant with no oversight or limitation on his power and authority. And anyone who defends Cap is basically saying that when the world is on the brink of a nuclear war, a single ship captain should have unilateral power to make the decision to fire first and start a war.

2. Cap is a former soldier in the US Army. So when Cap orders the Avengers to invade Sokovia and attack residents of Sokovia, is he doing that as an independent mercenary/solder-of-fortune or is he doing that on behalf of the US government? Since Cap is a former soldier in the US Army, Sokovia could easily accuse the US government of violating Sokovia's rights as a sovereign nation and call the UN to denounce/admonish the US government for sanctioning an illegal invasion of Sokovia.

So Cap wants to act unilaterally and wants to be able to choose, but his choices affect others and have consequences for others. But Cap doesn't give a shit about that because Cap just wants to be a tyrant with no oversight or limitation on his power and authority.
