Is there any criminal activity committed by women that is or could be justified?
Depends who is giving/assessing the justification. Many people of both genders consider that their offending behaviour is to some extent justified (“I had to do it”, “I didn’t have any choice”, “there was no other way”, “you’d have done the same thing”, etc, are commonly expressed views). Offences which might be viewed by a court as in some measure justified are those involving self-defence. There are cases of women who kill a violent partner after years of physical, psychological and sexual abuse receiving more lenient sentences than murder would otherwise warrant because the extreme provocation and the need for her to protect herself and/or her children is such a potent mitigating factor.
