The reasons for this behavior may be different. In most cases, such "domestic tyrants" are obtained from men who can not boast a particularly high status. But inside each male (whether cat, male or even a fish-sword-bearer) lives striving to become a "leader of the pack." Therefore, those who can not realize their ambitions in the society, proving its "strength and courage" in the family, strongly demonstrating, "who is in charge." At the same time desire to "trample in the mud" is particularly strong when a man feels that a woman in something superior to him, smarter, more successful in work, activity, and so on.
Another reason why men humiliate women - is the fear of losing it. Representatives of the stronger sex in my heart believe that if to convince her husband that she was stupid, fat, worthless and useless woman, to live close to where (except for him, such a noble and humane) nobody wants, the woman did not dare to leave him . And he's just what it is necessary: that will not go away and it was a century grateful that he did, miserable, happy. Surprisingly, this strategy often works, and husbands do manage to greatly reduce the self-esteem of his wife.
All of the above is characterized primarily for men with wounded pride that vent on women and their complexes resentment of the world. But sometimes it is mentally healthy and quite successful men nevertheless satisfied with his favorite wives "Italian scandal" with deadly insults and physical abuse. Them, then why is it necessary?
Perhaps, in such cases, the blame upbringing. After all, little boys are taught from childhood to restrain emotions: because men do not cry and do not outwardly show their feelings. But they are, if anything, fighting and cussing. It turns out that aggression - physical or psychological - becomes for many the only way to "let off steam". And there could be someone's arm was caught, he is guilty.
