I've watched humans destroy each other when I could stop it all in a heartbeat. Do you know what that does to someone after centuries? Could our mission have been a mistake? Are we really helping these people build a better world? We're just like the soldiers down there: pawns to their leaders, blinded by loyalty.
Since I’ve been in nonstop rant mode ever since Eternals came out on Disney+ I would like to mention how I love how the Thinkers were largely the ones who helped stop the Emergence, whereas the one who actively chose to fight against the team’s plan was the primary fighter of the team. It goes to show that you don’t always need to use brute force in order to solve conflict (although in some cases it might very much be needed)—sometimes you can use alternative options that don’t need to be obviously violent.
