If one choses to stay in an unhappy marriage and then becomes abusive its very very sad not only for the couple in question but for their kids and loved ones too. 

Many people sympathize with abused wives but when the victim is the husband he is met more with suspicion("he must have provoked her") and contempt("Is he a man?"). This is not right. No one should abuse anyone and just as a wife beater is trialled so should the abusive wives! after all a man who beats up his wife might also say he was provoked and oppressed etc. he too will have "his side" to the story.

And I know of couples, very very close to me, who got married by choice and still turned abusive with the wives being the more vicious abusers!
