No, the reason you see rape and murder as bad or wrong is because you have been raised in a society that sees these issues as bad or wrong. For a long time in male-dominated societies, there was no punishment for rape. Assaulting a female wasn't seen as problematic in the same way that it's seen as problematic now. That's a societal more that you have come to terms with being raised in a society which determined, at a very young age, that this was something you didn't do.
The same thing is true with sexual objectification. You grew up in a society (I did too) that said, for decades, that this stuff was acceptable. It's hard to admit that society might be wrong about this. It's far easier to accept that somehow it's normative when it's not.
Gravity-defying breasts aren't "normal." Breasts that large would sag, and sag tremendously. What's more, the female would probably be hunched over due to their weight, as there's no way to realistically hold them up with such a small frame. Again, even if we're talking fantasy we can assume that there are things like gravity, giving that when the characters jump, they come back down to Earth. Certain aspects of characters seem exist outside of such realities however, giving rise to mystical, gravity-defying breasts.
What's more, even from a statistical standpoint NONE of the women are as powerful as the men. The Sorceress's INT is A, the Wizard's INT is S. There's not a lot of explanation given here, but it does say that there is a mechnical implication that women are weaker than men in all faculties, even when women are pursuing the same practice (Wizardry). The case of the Amazon versus the Fighter/Dwarf presents the same mechanical problems. Even if there is some truth to differences in physical stature in the real world, if anything (including gravity-defying breasts) can exist in a fantastical game world, then it makes sense that females can be just as powerful, mechanically, as males. Yet they are not in this game.
