I feel like the game already does that by glorifying it as this casual, cool thing you can just do to others (as well as having it done to you). Making it some every day occurrence doesn't inherently make it less crappy... Rape used to be a lot more commonplace and less severe an issue through IRL human history, as was beating your spouse. With our more socially conscious present mindsets, we can look back on that and think it was crappy, even though it was "normal" at the time. I think it's fair to be able to say that about games that feature the same and in fact, I'll say it! It's shitty that this game prominently features rape in any light that isn't overtly negative. Though I don't at all agree that we should be able to kill off any and all NPCs we don't like, nor torture them, etc.
Tangentially, I can't help but observe that murderboners are viewed as a purely villainous thing here while rapeboners are generously rewarded through ample and extra content. It lets you really mull over the way people view and compare the "severity" of these two acts. People can apply "hentai logic" to rape and handwave it away or even call it cool, but just including murder regardless if it's portrayed sexually or not is too much for so many of you. I just find that interesting, I suppose.
Personally I'd rather have neither. I say take your rape and your murder and kindly shove off. Speaking royally, of course.
