[Minato says nothing at all while he listens, noting wryly that it was almost fitting how they were discussing something as heavy as a sacrifice while looking for survivors with little regard to themselves, the rubble seemingly framing all that's left of the dreams they once had.

There always had to be a 'but', wasn't there? He can't claim to know how it feels like living to see his friends die since his position's almost the reverse of Hiro's, but Minato's lips slowly flatten out into a wan smile as the other talks about being selfish, about wanting to fulfill the promises he had broken. In that he could say with certainty that they felt the same way and he replies with a quiet conviction that doesn't seem like it could come from someone as frail-looking as him.]

There's nothing selfish about missing what you once had, Hiro. I can't say I understand what it means to watch your friends live their lives while you protect them, but wanting to protect them and see them happy is just as selfish, isn't it?

You might have made that choice because there was no one else who could do it, but it's still a choice you made on your own...something you chose to do because you're human. [A pause.] Those feelings that you have are what makes you human, not your body or anything else.
