Do we have a dark side that we can’t help it? The self-responsible answer is no. It’s a character choice that needs to be consistent over time.
The process between the conscious and the unconscious goes as follows:
Every action and thought is motivated by the unconscious at some level. Some motives are temporarily not acted out as long as the mechanism of repression works. Distraction, stress, sleep deprivation, and drunkenness can release repressed behavior by activating the subconscious. Whatever we plant in our subconscious mind and nourish with repetition and emotion will one day become a reality. Therefore, there is no excuse for the stressed or drunkard who ask what took possession of them. All behavior in any situation, including the subconscious surfacing, is created through the conscious. One can only act out what was before accepted to be put into the self. Consequently, to learn to behave by suppressing unwanted behavior (i.e., because fearing negative social consequences) is not the goal. Instead, one should cultivate thoughts and a worldview that can only generate desirable behavior under any circumstances.
