This was such a tragic case, awful thing to happen and I agree with one the early pps who pointed out we can't possibly know enough about it to form conclusive opinions.
However, when the subject is one that affects the lives of so many, its natural that discussion will take place.
Personally, I think there's been enough research to show that people in shock often behave and talk in ways like she did in the video. We can't know, really, how much shock and disassociation played in her initial reaction to her attack on him but we should acknowledge that some women may well behave in this way when in a disassociation state because they've snapped after years of abuse.
We're also told that she behaved in a deliberately provocative manner. Now some relationships become toxic because the initial victim doesn't know how to stand up for themselves except by adopting aggressive and abusive behaviour too.
We can't know if this was the case here, but we can acknowledge that it happens in some relationships. What does seem clear is that they had a toxic relationship in which there seems to have been abuse on both sides. I've known men be the victims of awful dv by women and just because the balance of numbers swings the other way doesn't mean they should be denied justice or protection.
Being unable to prove abuse in court doesn't mean it didn't happen, so this could be an awful case in which an abused woman finally snapped, experiencing some sort of mental fugue state. Or it could be that she was the abuser who coldly murdered him. Or it could be that it was a highly toxic marriage in which a series of events led to her murdering him so horribly.
The jury found her guilty of murder and tbh, on the little we know, I don't see how they could have come to another conclusion.
That male violence against women goes unjustly unpunished, or lightly punished, is terrible and needs urgent addressing. Anything less than a life sentence for men who murder their partners in a temper or through claiming rough sex is abhorrent. But I think in this case we can't say anything other than justice has been served, however tragic the circumstances leading up to the crime may be.
It's hard to comprehend for some people that one of "our own" could have committed such a terrible crime, especially when we witness so many women denied justice and help when they're the victims of domestic violence, but if we deny that her guilt could even be a possibility then we are just as bad as all those men who claim Not All Men and deny their friend or colleague could possibly have raped that woman because He's-Such-A-Nice-Guy or a guilty verdict would Ruin-His-Life.
Their families will have to live with the reality of this terrible crime forever and probably with very little support. Their children must be going through hell.
