Psychology, as proclaimed by ignorant, hack journalists, will usually say, with enormous confidence, that this man is seeking ‘control’, is acting out a model given him in childhood by, typically, his father.
It is probably true that a high percentage of these wife-beating men follow this standardised profile.

It is also true that this does NOT apply to a significant number of such men.

Homicidal maniacs would surely be amongst these!
So, however, would possibly be some revered, God-fearing Archbishops.

Wife-beating is a well-publicised and ’serious’ problem today, but it was not always thus. In many parts of the world, it is still actually the norm!

i. ['Ownership' of ones wife is emphatically suggested by many of our Christian liturgies on the Sacrament of Marriage, for example!]
ii. [ In a nation that relatively recently practiced the ownership of slaves, this manifestation of ownership could well be abnormally prominent, for example!]

"She is mine, and I should not ’spare the rod’ lest my property becomes less valuable." is one such neanderthal response to a scenario such as the above! The wife-beating, I am sure, would sometimes be performed with calm regret, and in supposed obedience to religious teaching, etc.

I really doubt that this issue should be definitively dealt with here. Statistics and canned psychology are simply inadequate for the diagnosis of any human situation!

There is, however, no earthly reason why the woman should tolerate this demeaning, dangerous behaviour, and there is every indication that her husband is capable of doing her harm. This bullying behaviour is wrong [whatever the rationale], and she should not feel any pressure to stay with him.
Of course, she should not feel communal pressure to leave him, either!

There will come the day when he won’t be able to come back…that’s the day your friend will be leaving in a gurney…..

Can you talk some sense into her?

Most women would tell him to get lost. He likes knowing he can do anything he wants and she will put up with it.

Some men have this thought process "If I can’t have you, no one can " along with If they can’t be happy no one else should be either.

Yes, it is wrong and your friend should go to Abuse counseling and get away before she ends up dead.
