Fixed that for you. 
But really, in my opinion, her sincerity is real, but meaningless. WoJ has said that actions, not intentions, matter, and produce consequences.
I don’t follow Butcher’s q&a stuff from his marketing appearances, just the book (no short stories, either). An interesting side effect of this statement, though, is how we should then look at the death of Susan. If only actions matter, then Dresden murdered his daughter’s mother. And, that’s just one of the most obvious actions to revisit. I’d think a more nuanced perspective would work better otherwise, you’re into absolutism in a grey world.
What I like about this character, Deirdre, is that she represents both horror, ugliness and pain on one hand, but also victimhood, love and selfless sacrifice on another.
As most here would agree, she is a self serving, angry person with a long history of brutal and perhaps even casual violence doling out death when it suits her without a second thought. Her disdain for those outside her circle was made clear.
On the other hand, she seems to truly love her family and, for lack of better word, her colleagues. She was born into that circumstance. She was as much a victim of the denarians as any others cited in the books. Moreso than most, even as they got death’s release whereas she was moulded into complicity. She’s the twisted reflection of herself; her capacity to love, to care corrupted and turned on itself. Yet, she stll holds the capacity for love, for selfless sacrifice.
Anyway, I think she one of the more interesting characters in the books. Most are pretty shallow, but her appearance in this last book elevated the character over most of the others in the serial.
