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

As I have explained in earlier chapters, abusiveness has little to do with psychological problems and everything to do with values and beliefs. Where do a boy’s values about partner relationships come from? The sources are many. The most important ones include the family he grows up in, his neighborhood, the television he watches and books he reads, jokes he hears, messages that he receives from the toys he is given, and his most influential adult role models. His role models are important not just for which behaviors they exhibit to the boy but also for which values they teach him in words and what expectations they instill in him for the future. In sum, a boy’s values develop from the full range of his experiences within his culture.
