Steve nodded, wondering, as he had been a lot lately, whether the majority of this team was really built to handle the true weight of what came with this position. People would die. People would always die, and the bad would keep on coming, and maybe not everyone was prepared to deal with that. It wasn't something that was supposed to be easy to deal with. But...to make those hard calls, to be an Avenger, you had to be able to set your fear aside...push on through it, for the good of the people you were fighting to protect. Pietro and Wanda were just two kids from a messed up home. He never should have brought them into this.
"...In the war..." Steve started, trailing off and thinking about how to phrase this, "...we were fighting for a good cause. And...we had to to do some...terrible things to get there. And you learn that regrets not something that's black or white. You can feel pride and regret. You can know with absolute certainty that you would make the same choice over and over until the end of time, and still regret the consequences of your actions. And no, the regret won't help anyone, or change anything. But it makes you a better person for having felt it. And...I would hope, for your own growth, that you can learn from this."
