I give her the benefit of my doubt when it comes to brutalizing female characters.
It's all about tone. Something like Carol Danvers' torture in MS MARVEL, or Temi's recent rape threat in SECRET SIX, passes the test because of how the supposed victims reacted - specifically, not like victims. There was never any question, to my mind, that no matter what happened to Artemis, much, much worse was going to happen to whoever did it, and she herself wasn't going to be broken by it. She's defiant, calm, and dangerous; there's no trace of fear or helplessness in her, no sense that they have any power over her beyond the simple, very temporary, physical fact of her chains. She reacts like a male character would, and like any hero should, with confidence and control and effective forward action (taunting the guy into hitting her, which stopped him pawing her).
Brutalizing a character is fine. It's required by the genre. It's just that female characters are generally victimized instead, which is not okay. I typically trust Gail to know the difference, which means, yeah, I'm not nearly as skittish about that kind of set-up when she's writing as I would be most other comic authors. It's more about her cred than her gender, though; Rucka's got a good track record too, for example, so I'm not real concerned about Batwoman's apparently unrevealed "tragic past," and I was never skeeved out by Chase's kidnapping or the border abductions in MANHUNTER, so Andreyko gets similar leeway with me.
