Whether it's women or anyone else you can't really pretend morality plays no role in this world, because "nature".

I understand that a lot of RPillers don't even believe in morality, but the fact remains that some make it seem like women's bad behaviors should somehow be excused because "female nature".

That's not how it works. It's like saying "this person has natural sadistic tendencies therefore whatever he does is not his fault!" or "serial killers did nothing wrong, it's not their fault they're sociopathic"
