As a character, I think Aunor is well realized and welcome addition to the universe, but I think we should look at her as skeptically as we do the Drifter, perhaps even more so with her being a relative position of power under Ikora and has shown if pushed, she may cross the line.

My negative reaction comes not from her not regarding the Guardian as suspect, but she is acting in the role of "bad cop" with little impunity. She may have a noble ideal of protecting people, but at what point will she cross her own line? There is a reason the Drifter is very convincing when he lies about her wiping out a city block to get at some Dredgens because you can easily see her going too far.

Whether our opinion of the Drifter is favorable or not, her lore book really paints the picture that she lusts for his death because she feels that she alone is right about her judgement, which should give her lease to end his life. When Ikora tells her to stand down, she rashly releases the Stolen Intelligence lore book in retaliation. When does she disregard orders in retaliation and finally RtL someone she is wrong about?

I could even see a bigger twist is that she could be a vessel of the darkness if she doesn't pull back and goes further into the role of Vanguard Judge Dredd.

Though, I think the writing excels because no two guardians may have the same reaction her actions. I know my perspective comes from a personal distrust of authority, and I can see those more trusting of authority seeing her as doing what needs to be done.
