I don't imagine that he did. [ Mahito certainly wasn't someone that went out of his way to endear himself to people in any way. ] It's not a kindness, but she was certainly someone that essentially offered herself up to be the perfect victim for a more apathetic killer to target, no matter how unintentional it was. Agreeable, and vulnerable.

... I wish I could say, Meg. But with so few of us left, it needs to be soon.
