You are not pushing facts...you said they were innocent. They are not. D&D facts are that the GUR are monster killers and they do so for hire. The headcanon that you are pushing is the innocent part. That is my point.
They are guilty before those whom they called "monsters" and for whom they were paid money. And we "monsters" are guilty before them. And the fact is, it's the same as always, " who wins is good".
