CoC2 unlike CoC1 really does not allow your main character to be an asshole much. In CoC1 you could practically be a walking murdering turborapist. Not that it was well written, but it was a thing.
I'd guess the places where they get paid have policies that disincentivize this sort of stuff. Patreon for one isn't fine with content like that.
I feel like patreon thing is just an excuse. I mean, this one of more popular and sucesfull western indie porn games on patreon and at large. It did well on steam selling 10 000 "units" in its first month which is more then a lot of higher budgeted porn games actually accomplished. And that is with free version being available. And I do not think that anything really stops them from moving there main money earning method away from patreon. Like to subscribestar or something similar. Since, well, no matter how much everyone complains about this game (justifiably so) it is one of few games of its kind and it is also updated frequantly. Which is something of a rarity in itself for western hentai games. So we and everyone else are lacking in options here so we are stuck with Savin and Co. So we are forced to follow them.
And besides, I do not think that Patreon is that concerned about its rules. Only thing they really seem to have problem with is hardcore PC incest, "realistic" depiction of violence and rape and shota/loli content. So I do not think that is the real reason for lack of content that can be described ass "fuck this world in most literal sense".
No, the real reason why there is no corrupt/evil contents is because,frankly, most of authors are just not that interested in it to begin with.Like, for example, both Bubbles and Some Kind of Wizard are not really into the whole idea of corruption. SKOW flat out said that she is not interested in supporting corrupt hive along with corrupt Azzy. She will never be a companion as she herself said. Since it is more work for her for things she personally does not enjoy to write. Now, this could be because we are in early stages of the development (that took four year but whatever). But nothing is really giving me hope since I feel like only Savin, B and Wsan are into it. So future corrupt/evil content seems to be like afterthought like current batch of it is.
Another reason why I am not that hopeful for a corrupt route is because it does seem like a lot more work for a lot less payoff. Now, while I am not sure about statistics, I bet that most people that play games default to good guy route even if evil one is just as interesting (which this one currently certainly is not). Which probably makes it lot less appealing from writers point of view to write something that a lot of people would not interact with. Combined with it just being a lot more work on writers plate.
I know that this is there job and all, but I can see how that could be seen as to much. Lets look at Wsan as most extreme example when it just comes to corrupt companion content. Not only does he need to write content for 2 pure companions, he would also need to write stuff for there corrupt conterparts.
Now there a ways around this. You could write content, quest and characters that only have corrupt routes. That way, when writing something, you do not need to worry about splitting your attention for both and corrupt and pure content. Or some other ways I am not currently thinking of..
Still, I could be wrong. I do hope that there claim that, since Kassyra released her daughters, corroption will be more prominent in the story. I at least hope. As things stand, stuff like enslaving genderbend Hirrurd, Wsans "break the dom" routes and teases of Cait/Brienne demon forms could pave the wave for something more substantial. But at same time, those are things Wsan and Savin wanted to add from beginning so my comment for the rest of authors still stands.
I hope I am wrong since I like playing as jackass-
