[That's the problem with killing. It gets easier, the more you do it, even when it's necessary.] Or because you want to, [he echoes, nodding a little. That sounds like maybe the root of the problem, right there - determining whether Helena truly wants to do this, or whether she's only been programmed to believe she does.

And determining whether there's truly a difference. He believes - knows - there must be. But he also knows how convoluted it can get, trying to find that answer. It's why he has no solution to the biggest thing weighing on his mind back home. It's why he's here.

It's almost ironic.]

Maybe she doesn't. Maybe that's what this is about - getting her to figure that out. [Steve shrugs a little. Bucky's been here longer than he has, and he's got more experience. This is his thing to solve, although like hell Steve's just going to let him flounder, if he can help.

He's also here to remind you, when you need it, that you're doing the right thing. Because he absolutely believes that. Bucky's heart is always in the right place.] Well. Just in case you needed reminding. [Because he knows Bucky would be the first in line to remind him it wasn't his fault, if something like this had happened. Even if maybe - definitely - he wouldn't be convinced.] I guess the important thing now - right now - is damage control. Make sure it doesn't happen again. Work from there. [Because just plain punishment isn't going to work, in a case like this. They both know that.]
