That's not the point. The point is that that isn't what the girl in this scenario wants, and there are ample clues that she isn't thrilled about it when you have made rough choices in the past. (There are also ample hints, through his internal monolog, that choosing those options is making the MC act/think more "evil", for lack of a better word, as well.) If you chose to ignore those hints and continued to choose the rough option, that is entirely on you.
There is absolutely some implied judgment going on here, but it isn't about rough sex in general. It's about engaging in rough sex with someone who is clearly not completely and enthusiastically into it, even if she does not explicitly say "no".
This game is not meant to be an open-ended fantasy simulator. It's a dating sim. Many, if not all, of the girls have a "right" and a "wrong" way to approach them. That's what makes it a game. If you fail to come to Sara's rescue (whether it's your fault or not), she dumps you. If you insult Ashley, she dumps you. If you abandon Kim in the club to go to Sara's rescue, she dumps you. This scenario is Roxy's success/failure criteria. She wants to be dominated, but she also wants to be cherished and protected. Get the balance right, and she will rock your world. Get it wrong, and she is completely capable of wrecking you, or at least your balls.
