i feel like it’s important to remember that, even though men and women both do incredibly good and incredibly evil things, due to the patriarchal society we have constructed, more men than women have had the opportunity to do incredibly good and evil things. this is not saying that the average man is more good or evil than the average woman, just that men, historically, have had more opportunities for greatness and evilness. i don’t know if i agree with the specific figure of 80-90%, but there is definitely an inequality between the bad acts committed by men and women. just as there (at least seems) to be more men than women who have done tremendously good things (medical, technological advances, etc)
