Hatred is important as it means “strong aversion.” The experience of hatred tells us that we feel that the object of hatred is bad for us. All emotions are based upon logical reasons. All we need to do is find out “what are the reasons the emotions that we are experiencing?”
In psychology, Dr. Sigmund Freud defined hate as an ego state that wishes to destroy the source of its unhappiness. In a more contemporary definition, the Penguin Dictionary of Psychology defines hate as a "deep, enduring, intense emotion expressing animosity, anger, and hostility towards a person, group, or object." Because hatred is believed to be long-lasting, many psychologists consider it to be more of an attitude or disposition than a (temporary) emotional state.
Hatred, anger, fear, irritation, frustration, etc.. are not "bad feelings" as they are based in real and logical reasons. Becoming aware the logical reasons that gives rise to our emotions and moods is called "Emotional awareness" or "Emotional intelligence."
For example, “Good people don’t get angry or hate anything.” This sort of learned behavior can be counteractive to the process of understanding and then mastering our emotions.
We need to understand our emotions and to do this we need to tune into the full range so that we can understand how and why they operate and how we can be in charge.
UNDERSTANDING NOT REPRESSION
Being in charge does not mean repression it means understanding. The person who thoroughly understands the “how and why” of human emotions is able to control their emotions – to suppress when not appropriate. To suppress when they feel that they may react robotically, without awareness, but not to repress as in the example of somebody who cannot tune into or understand their emotions.
The repressed personality is still a victim of their emotions and moods. All the repressed person had done is to learn how to squash their emotional responses to life. This produces a dry and lifeless person. This is not a healthy personality to emulate. The repressed personality is an unhealthy and dangerous, as the repressed emotions begin to disturb the person and their interaction with life.
Constant and habitually repression leads to illness and can be nasty for other people.
A repressed personality can often be like a time-bomb waiting to go off. Many repressed personality types feel so confused and ill-at-ease with their emotions that they either adapt a robotic life repertoire of inflexible routine (to keep their minds off the repressed feelings) or try to numb their confusion by substance misuse (eg: alcohol and drug misuse).
The repressed person may have many life issues and developmental stages that they need to go through – they need to gain these experiences to give them confidence in life. This is made easier if they admit and acknowledge that they have issues and problems that need addressing.
If approached with honesty, humility, respect for life, love, and an openness to trustworthy advice then this can actually be fun. In matters of romantic relationships we need to be open to rejection, failure, and being hurt – but that is life and all things pass and become healed with time, patience, and insight.
