[Newt sighs. Okay, she has a point. But it can't be that simple.]

It's not like the world is neatly divided into good and bad people, Alphys. [He doesn't know her world, sure, and it seems pretty different from the setup he's used to, but that kind of thing has to be true across the board.] Maybe you're not that good, I don't know, but you're not bad, either. Bad people don't feel bad about making mistakes. You're clearly pretty upset about this, ergo you're not a bad person. Not in my opinion, anyway. [And he considers his opinion to be fact, so.]

Look, if you really want to make things right, there has to be a way to do that. You're smart. You'll figure something out.
