Maybe it's me, but "Comforter caused the Hurt" sounds more ambiguous than "Comforter is the one who hurt them" to me. The first doesn't imply the the comforter meant to hurt the other person, it can be used for accidental hurt. The second sound to me like the comforter wanted to hurt the other person.

Anyway, they aren't my tags/kinks so I have no feelings in one way or the other about them.
