Why won't the Avengers help the "irrelevant" people?

And it just happened. The total destruction of the city just happened like one second before

Kind of like how Han and Leia kissed on Endor right after they saw the Death Star blow up in the sky. Like I said before, it's a natural reaction to celebrate the end of a war immediately by hugging and kissing someone you love. So there was nothing wrong with Superman and Lois kissing after surviving what could've been the end of the world since that's the natural reaction for anyone surviving such an event.

But Steve Rogers waking up after 70 years and instead of asking "Did we win the war? or "Who won the war" and instead of being glad and relieved that the war is over, Rogers doesn't care at all about who won the war and is only disappointed that he didn't get to go on a date with Peggy Carter. That's much worst than 2 people sharing a kiss after surviving what could've been the end of the world.
