The Pot Calling the Kettle Black

Helena assumed she had far more power than she actually did if she believed she could turn around and seek to see Bethany punished for speaking her mind.  This was not the world she'd been born into when Templars and their Chantry minders could do more or less what they wished.  No, the playing field was far more equal now and she wasn't afraid anymore.  Still, probably best to let Helena believe she held power for the moment.  Bethany could always disabuse her of that if need be.

So instead, she laughed.  Perhaps it was meant to be a chuckle, something to lighten the tension, but it came out bitter and disbelieving.  I know full well what I have seen over the years.  You can feel free to ask around - there are others who can corroborate everything I've said.  Helena hadn't even gotten half the story or any of the details and still bristled.  She had no idea.

As for Dairsmuid, who said anything about blood magic?  They were simply living as they always had, following their own centuries-old traditions which had caused no trouble for anyone.  And they were murdered for it. Bethany hadn't been there, but she'd seen the reports.  She was well connected enough to know the truth of it, and blood magic had nothing to do with it.

I will grant you, however, that some of the vilest things I have ever seen did stem from blood magic, but blood magic isn't around every corner.  Sometimes evil hides in plain sight, no magic required.  Nor was it always awful.  It usually was, yes, and Bethany had no intention of ever using it, but she couldn't say that everything the Wardens did was evil, for example.  She didn't like blood magic, and in her mind it would forever be linked with terrible things, but objectively she couldn't say every single use caused harm.  And besides, the Templars themselves used blood magic.  After all, what were phylactories if not that?
