Have you ever met someone with emotional issues, i.e. anger management issues? There are indeed many people with habitual "programmed" emotional responses which are detrimental to their well being and are extremely difficult to manage.
You might like to read the works of the evolutionary pyschologist and athropologist Dr. Paul Eckman. He posits that emotions are valuable life saving forces that help us act quickly in critical situations without having to think. However, our emotional habits have also evolved over many thousands of years, and so many of the emotional responses which may have saved our life as a paleolithic hunter gatherers may no longer be relevant and can have the opposite effect in a civilized society.
