I agree with this.
I'm not, from a storytelling/drama/thriller/horror side of things opposed to a couple of things. I'm not opposed to vampires being used in stories to tell rape allegories. Because they basically always have been that. You know, provided a story is willing to go into that territory and respect it and have it have meaning and consequences. And I'm not opposed to femme fatales just walking all over the boundaries of heroes, because again, that's part of the stock trope. They seem kind of alluring but just smash your boundaries and make you question your heroism and everything else. And Nocturna wound up being both a femme fatale and a vampire character so the tropes are just magnetic and bound to occur. Using things as pulp story tropes doesn't give them the level of respect they deserve, though.
I remember thinking about it at the time. I do think, particularly in the case of your detective/street crime crime-buster characters, they're going to meet bad people, and bad people are comprised not just of murderers or thieves, but also rapers and stalkers and other their ilk. But encountering these seedy characters is not the same thing as our lead characters experiencing rape and then "end story arc", fresh start next month, true believers! Pretty cliched stuff.
If a murderer successfully murdered Nightwing in an issue you'd probably expect some kind of follow-up.
