IRL, It's bad moral-wise. It always had been, it always will be.
That being said:
At the same time, story-wise, let's be real, man or woman, if they forced themselves onto another, man or woman, it'd be bad, it'd be evil. BUT they ARE the Enemy. They ARE the villain.. They ARE evil. What we think as moral, or wrong, or evil, does not apply to their way of doing things. A villain will do- guess what- villainous things. They don't care. Murder, pillaging r*pe, or destruction. Evil is evil. They might understand it's bad, but, ultimately, they DON'T care, or have a stupid reason to, or some background nonsense that made them like this, whatever, it's a normal Tuesday for them, man or woman. Evil will be evil.
IF!! IF the HERO did this, man or woman? THAT would be truly evil, because they know, and understand, and are definitively choosing this route of action. They would be, in my opinion, worse than the villain.
Both aren't good paths forward, and both are equally bad, and its evil. -but I also think that's the point when being written into a fictional story. It's meant to be EVIL.
