I wonder about this. I know its difficult to know the further back one goes. But I do think there was a greater tendency to believe both sexes were capable of moral and immoral behavior. There appeared, in England at least, a striking shift between the 18th and 19th Century. One measure of this might be the dramatic fall in the % of the imprisoned population which were female, from about a quarter in the 18th Century to 5% in the late Victorian era. Most of this was achieved by "reforms" that made females not responsible; for debts., for crimes "influenced" by husbands or lovers, crimes where their mind was unbalanced etc. Prior to this busy period of legislation making in the mid Victorian period the attitude had a more individual responsibility cast. Put simply each person was responsible for their sins whatever the temptation or excuse. That's not to say there wasn't the usual gynocentric background to this but I do think there is a shift. Curiously I was first alerted to this by "Marxist" feminist researchers who made a distinction between the "conditions" of women in the agrarian era and the rise of the Bourgeoisie particularly as the industrial revolution sped up. Typically they decided this was worse for women as they were "denied agency" by the protective cloak of "benign sexism" that raised women on to a pedestal and surrounded them with protections from being held accountable for "sins".
