I can't avoid feeling conflicted with each episode, and I think that's exactly what the author wants us to feel.

Karen, although she's strong and truly believes in what she does, is still naive, and sometimes strength is not enough.

Because of this, Araragi-kun tries to take care of her, after feeling guilty? In this specific case, it makes me wonder: are we, the viewers, the ones with a twisted and perverted vision of what's happening, while what is happening is actually something natural? Or is it just unwarranted fan service?

Beautiful photography, though, as always.
