This only reflects a tiny part of the Indian population but, within some circles, Indian women will stick by their husbands sides despite ANYTHING. A saying in Hindi is "Pati dev" which roughly means "your husband is your God".
I'm not trying to insinuate anything by sharing this here except that it was an interesting (albeit anecdotal) experience that I had. I have close friends who have had arranged marriages which are thriving respectful relationships.
Even if she was in the middle of punching me, if you started walloping my wife with an umbrella, my frame of mind would immediately shift from wherever it was to "my wife is being attacked by an umbrella-wielding stranger."
