Cylons being manipulated by other cylons doesn't absolve them of guilt.
BSG did have a few instances of the reverse of OP's question tho -- where the "good guys" turned out to be bad" -- trying to say this without spoilers; it's a 20 year old show but ffs of you haven't seen it, go see it now.
- the (temporary) new admiral
- several main characters during the part where they live on the dirty planet
- a very specific set of seven main characters (wink wink) ... .and more,..
And there's one specific example of the full 360 -- a character that starts good, turns bad, but turns out they were actually good all along. I won't give the name, but they were passing messages to the resistance.
That show was awesome.
One note tho, on the topic generally: flipping character alignments is a frequent pre-shark-jump thing, and is often bad writing. In BSG, tho, all of the "flips" are pre-planned, or at least 100% true to their character (eg the 360 example above).
That's kind of an individual thing. Like, I get it, I get what you're saying, but, when I think about the books (which I used to love), I just didn't think of them fondly anymore; I can't think of any of those characters without that irritation and disappointment coming up.
I was super excited about having my kids read those books -- and my oldest started the series, but then needed a break to mature a little before hitting book..3 I think? Idr. And now I just don't really care whether they read them. (If they do choose to read them on their own, I won't tell them about JKR until after they've finished them.)
However I have no problem setting aside the shittiness of Knut Hamsun or Henry Miller; I still really enjoy their books. Heidegger? Too shitty for me. Picasso: meh, he's fine.
That's My Hot Take: if it bothers you, acknowledge that, and don't force yourself to be uncomfortable. But also don't shame people for whom her toxicity is something they can set aside.
(As long as they are setting it aside and not enjoying the work because of her toxicity.)
That said: pirate her shit, you don't need to give her money.
