Quote from : Why Does He Do That?: Inside the Minds of Angry and Controlling Men Book

ABUSIVE MEN COME in every personality type, arise from good childhoods and bad ones, are macho men or gentle, “liberated” men. No psychological test can distinguish an abusive man from a respectful one. Abusiveness is not a product of a man’s emotional injuries or of deficits in his skills. In reality, abuse springs from a man’s early cultural training, his key male role models, and his peer influences. In other words, abuse is a problem of values, not of psychology. When someone challenges an abuser’s attitudes and beliefs, he tends to reveal the contemptuous and insulting personality that normally stays hidden, reserved for private attacks on his partner. An abuser tries to keep everybody—his partner, his therapist, his friends and relatives—focused on how he feels, so that they won’t focus on how he thinks, perhaps because on some level he is aware that if you grasp the true nature of his problem, you will begin to escape his domination.
