I hate the term Torture Porn and wish people would stop using it. I understand the reasoning behind it, a la, "I get off on watching people get tortured (fictionally), and this movie tittilates me in that way." The problem is a) the term "porn" will cause many people (including respected critics like Roger Ebert) to misunderstand the term, and think that it includes sex or nudity, and b) Torture Porn films are fictional, where the torture is acted, but in pornography the sex is real. (Not counting Skinemax style softcore, which can barely be considered "porn.")

So ignoring that term, you're asking about movies where a woman is responsible for sadistic torture.

Good examples I can think of are:

- Hard Candy
- American Mary
- The Girl Next Door
- Ilsa, She-Wolf of the SS
- I Spit on Your Grave (remake franchise) focuses more than the original did on using torture in the revenge
- Salo (both males and females inflicting torture)

From your examples, The Loved Ones is a good one, where the theme truly is about torture, and the monster is a woman.

A'Linterieur is not really a torture film, but the female antagonistic is certainly sadistic, and inflicts plenty of harm in her quest.

[SPOILER]
Haute Tension is not a torture film, and the viewer doesn't know the monster is a woman until the end. Like Inside, she does inflict plenty of harm though.
[/SPOILER]

The Saw films are torture films. The female antagonist (Amanda) is really only directly applicable to Saw 3, where she begins to construct the torture traps herself and becomes even more sadistic than Jigsaw. [SPOILER] I guess you could include 2, although that would be a spoiler, and she's not really doing the torture in that film, just helping capture people. Including Saw 1 seems like a stretch.

I just noticed that the title of your post includes "hyper violent movies," not just torture porn. In that case, I would definitely include A'Linterieur.
