[MCU] In AoU Captain America said they couldn't leave a single person left to die on Sokovia. In Civil War he says you can't save everyone. What changed his attitude between these events?

You can't "leave" a single person to die. You try your best, save everyone you can. That's why, in the First Avenger, Cap goes to save the captured soldiers. Sure he might not save everyone, but he's going to try.

Things like Sokovia show him that not everyone can be saved. Huge, extinction level events can happen, and you can't save everyone. But so long as Cap is still alive, he'll keep trying.

> This job... we try to save as many people as we can. Sometimes that doesn't mean everybody. But if we can't find a way to live with that, next time... maybe nobody gets saved.

You can't save everybody. But if you stop trying, everybody dies. You have to *try*. No one gets left behind on purpose.
