Isn't it more likely that she's simply a murderer?
a man gets set on fire and killed, and we blame the victim, as a society we have to, we have to view women as being completely incapable of malice, it HAS TO be the man that MADE her do it.
a man that sets his wife on fire doesn't get a free ride, when was the last time anyone ever blamed a female victim for being killed by a man?
