[The silence is intensely uncomfortable, and he knows that it's probably hypocritical to care so much about this, when he's killed others with far less concern.]

I think he would have taken longer to do so. And he would've had more trouble hiding and gathering a competent army.

[Coulson makes sense, but he's never been able to keep himself from 'what ifs' and 'maybes'. What if he'd been a better brother? What if he'd just taken the money Swordsman offered? What if he'd just stayed with the circus instead of killing?

It's never helped.]

He made me into everything I've tried to avoid becoming. Or becoming again.

[He says it quietly, lips pressing into a hard line.

He looks up sharply when Coulson mentions his mistake, frowning a little.]

You didn't make any mistake. Loki would've killed anyone he encountered, I don't doubt it.
