And he's quiet as he listens to Vash explain something horrible happened because of him, his expression non-judgemental. Just sad.]

But you already are. The moment you looked upon what had happened, and said "I want to be better". And then you kept to it, did you not? You said you vowed to never take another life again. You may not see it, it is truly hardest to look at ourselves and see the good around what we believe to be flaws, but I feel you have lived up to it.

[He won't ask if Vash caused it deliberately, accidentally, or simply by existing. He refuses to judge someone. Instead he offers Vash a smile, an actual true smile, untainted with the twisted love of before.]

I do not know your entire story, I will not judge what this place made you do, but if your love was so complete that in this worlds way, taking them out of it to spare them misery was the only thing it made you do... Then I think you are a better person. More than you think.

[He didn't dig his fingers into someone, peel them open like grotesque candy wrappers, all while decrying that their pain was right and just if they wanted peace.]
