Some people say they do not understand how a whole nation could become sociopathic in a short time and kill so many people who did nothing wrong. The answer is they did not become sociopaths nor psychopath (people are born psychopaths) nor had they been ´programmed´ to kill. The answer is it not as simple as some may think. The Germans were under the influence of human obedience, propaganda and used dehumanisation not to feel guilty because of their crimes.
There are many films presenting the cruelty of the Germans during the WWII, museums with every hall showing a different story, history lessons only on this topic. It all has a reason, during the war as many as 80 million people lost their lives either as soldiers or civilians, which accounts for 4% of the world population in 1939. It is the deadliest conflict in all human history considering the crude number of deaths, therefore it needs to be remembered as a statue of human deprivation, hubris and cruelty for every generation to derive lessons from it and never let the history repeat itself.
People who tried to diagnose the 24 most important people of the 3rd Reich who were captured after the war said that the men, although showing some signs of pathology or lack of empathy, could not be diagnosed as mentally ill and seemed fairly logical in their speech and reasoning. This indicated that there must have been some other reasons for the cruel behaviour. Rudolf Höss, the Commandant of Auschwitz, said ´I thought I was doing the right thing, I was obeying orders, and now, of course, I see that it was unnecessary and wrong. But I don’t know what you mean by being upset about these things because I didn’t personally murder anybody. I was just the director of the extermination program at Auschwitz. It was Hitler who ordered it through Himmler and it was Eichmann who gave me the orders regarding transports.´ This gives a hint at one of the most important factors- human obedience. A famous experiment by Stanley Milgram showed interesting yet terrifying results showing the extent to which humans obey orders. The experimenter tried to show that Americans were less obedient than Germans, however starting his research in the USA he was scared of any further discoveries. Milgram constructed an experiment in which the subject was supposed to ask question to a person (the subject did not know it is not a real person, they heard only sounds)and had to give an electrical shock for every wrong answer the ´learner´ gave. The subject was told it will be an experiment on learning and that the shocks may influence the rate of acquiring knowledge. With every incorrect answer, however, the subject was to give a shock 15 volts stronger than the last. The subjects were informed constantly by the machine whether the number of volts was dangerous and could hear response from the ´learner´ (previously recorded voice). What Milgram observed in one of the first experiments was that more than 60% of the subjects went up to the 450 volts, the highest possible number and probably lethal (which they had been informed of beforehand). This showed that humans do obey even if the orders can be lethal in effect and the person hurt is giving strong signals of their pain. Many subjects protested during the experiment, asked to stop and see whether the ´learner´ was fine, yet not even half did in fact stop. In one of the transcripts of the conversation between the experimenter and a subject, the latter is constantly saying ´if something happens to him, you will be responsible´and then continues to shock the ´learner´. Milgram´s experiment showed that humans under orders are more likely to do harm to others and how without responsibility for our actions we are able to do more than under usual conditions. This indicates one reason a simple German soldier could be able to kill a Jew, a Pole or any other innocent person, they were simply given orders to do so and the responsibility of these acts was taken off their back.
When a human hurts another of his kind he or she may feel guilty, only bad people feel guilty as they did something unforgettable. This breaks a person´s image of themselves as a good and just being, which cannot be tolerated by the conscience. A conflict is created between two contradictory psychological truths, one of being a just and good person and one of being guilty of hurting another of one´s kin. This conflict, in psychology called cognitive dissonance, makes the person feel unease, which needs a solution, which can be in form of regret or many other things. Yet one way of resolving the dissonance is not to focus on ourselves but to wonder what did the other person do to deserve to be punished. If one is a just and logical being they could not possibly harm without reason, therefore the victim is guilty of something, for example they are Jewish and ´as we all know Jews are greedy´. This can go even further, if I did something while I am a good person then it must have been something moral and not outstanding, harming a human is in fact immoral, but my ´victim´may not be a human. In this way one can reduce a human victim to an object or a creature which does not deserve moral treatment, this process is called dehumanisation. In this way soldiers can protect their self-esteem as they are not really harming another person, only a mere creature. It is a mechanism which helps some forced to harm, but also it makes people hurt even when not ordered to do so, for example Hitler dehumanised Jews during the World War II. Hitler thought of himself as a good person because he did not order to kill people, in his mind Jews, Poles and other nations were inferior to Germans. Dehumanisation is another answer to the question of how Nazis could kill so many during the WWII even if the ones who killed the most were ordinary people taken into the army. A great example for this is the idea of concentration camps, people were not treated as equal, they were objects which were to be exterminated. Gas showers show how people were not considered as single units but as a group of rats. Dehumanisation is what makes soldiers treat civilians as rubbish, what makes people laugh at others and what every person does to some extent when we feel guilty after hurting others (depreciation is reducing somebody´s value).
Human obedience and dehumanisation are only two aspects of the various reason why Germans were able to do such cruel things. The mechanisms shown here are in use during all wars, whether it is the Roman Empire, the WWII or ISIS. Studying them helps us understand that these people do not differ from others, they had been simply affected by factors which triggered mechanisms which pushed their boundaries much further. However, an important note has to be made, psychology does not in any way try to pardon or take responsibility from the Germans who killed during the war. All crimes must be punished as actions against humanity and all must remember what was done, what psychology does is providing understanding of the cognitive processes which occur during such events. The victims of the cruelty of the 6 years of war shall remain in the hearts of many longer than any person alive today will ever live, never to be forgotten. Our duty is to understand the events of that time and never let the history repeat itself.
