Literally all it takes is one man on that jury with the mindset that women are to blame for a man's transgressions.
I know this seems implausible given what we know, but these men exist everywhere. There's even some women who buy into the trope that if a man cheats, it must be because his wife has some sort of character flaw.
Look at everyone in the beginning who was assuming that it was SW who was terrible with money just because she was in a MLM? Or because it's the automatic assumption that if a woman doesn't hold a "real job" she can't possibly be responsible with money? (Sorry, but I've never held a "real job", been married since I was 19 and a SAHM, and I handle all our finances since our bankruptcy 14 years ago. A bankruptcy that was due to medical debt from an unforeseen medical emergency where I was close to losing my life. I have rebuilt our credit, and I pay everything on time and don't own frivolous things other than the photography equipment I have personally saved for by selling my artwork. My husband works full time, and I love him to death but he is impulsive with spending and not attentive to what gets paid or when it's due and he knows it so he has me handle things.)
There are plenty of men out there that think when men get out of control in a marriage, it must've been provoked by the woman.
That if a woman is raped, it's 'cause of her choices. What she was wearing, because she was drinking, etc.(Same line of thinking.)
All it takes is one of them on this jury. One. One of them to buy his BS story that she killed her babies.
