Most of the writers have clearly grown far too attached to their pcs to let us abuse them. I can kind of understand, I've been a DM for almost 20 years now, and having to hurt some npc I love would pull my heartstring but this is a porn game. Nobody is invested in the story.
I like being a piece of shit netori fat bastard, I like being a harem master vanilla boy and I like good old ntr. Let me break Ryn into a pathetically adorable dependent trap boi, let me corrupt Cait into having even less self-respect than she does now and -truly- become the village bicycle, and let me abuse Kinu to give her an actual reason to hate me... Oh well, at least my anger at wasted potential keeps making me feel alive.
Honestly, I always saw Corruption genre being sort of separated into two areas.
The serious corruption and the goofy corruption
The serious corruption refers to stories that involve corruption that take place in a grounded world with a serious, believable stories that you can imagine happening to someone IRL. It's the reason why Emergence had a period where it shocked people, due to being presented as a more realistic take on the idea.
The goofy corruption refers to stories where the characters basically exist to be corrupted (or have that option). There isn't any drama in it - you are enjoying... dare I say it, a power fantasy of being this bastard who's cock turns any girl or boy into a total slut. There is little logic to it - if the story wants characters to become corrupted it will get there in the hottest, most bat shit unrealistic way designed to fulfil a fantasy.
CoC2... I can't view it as a serious story. It has moments and beats I can take seriously, but for me, it's a story about an average guy with a big cock who recruited a slut that can heal him and fucks anyone as her religion and a massive hunk of a bull who is his bro he is willing to bang chicks (and boys) with, who go to the forest to stop evil Red Woman and 90% of the local populace wants to jump on their cock. This is goofy and with good writing it's a simple, yet fun premise that can still include worldbuilding and story that is engaging.
Dark Knight, especially if it was actually realized well, could in theory make the game more grim with options of making characters vastly different, but in a way that is still activating my cock. However, it's really hard to say for me if it would be the right way to actually add corruption to the game.
Do I want to be the bastard that makes woman cry before turning them into mind broken sex slaves with Tobs being forced to write a 20 paragraph long descriptions of their inner conflicts and struggles? Or do I want to be some Dick Dastardly Richards, who turned his goofy pink cat into the local cum dumpster who enjoys every second of her new life and still goes onto the usual adventures with the MC?
I believe this is one of the reasons why Dark Knight is so undercooked. Devs aren't sure if Dark Knight should be this edgy, grimdark story or a vessel for the player who wants to enable as many degenerate and immoral content as possible without being barraged by angst that writers themselves aren't too interested in, because they care about
their story the characters that they've put in the game too much. They take the story of the game too seriously to take a piss and embrace the goofy corruption, yet are too attached to do the serious corruption.
