Is It Ethical To Fictionalize The Holocaust

In 1933 through May 8, 1945, six million Jews were killed by Adolf Hitler's Nazi regime and its collaborators. Some historians believe that the Holocaust included the killing of 5 million non-Jews bringing the total to exactly 11 million (wiki). Other than the Jewish, Slavs, Soviet POWs, communists, homosexuals, Jehovah’s witnesses, and the mentally and physically disabled were other victims of this genocide. This chaos was known as the Holocaust or the Shoah. Ever since 1946 movies have been made every year since the following year (wiki). Only a year since the dreadful event occurred. "The stranger" directed by Orson Welles was the very first feature film to include footage of concentration camps. With that being said there is over hundreds of films dedicated to the Holocaust. could it be ethnical to the Jews, homosexuals, and the mentally and physically disabled?
Yes, first-hand testimonies of the Holocaust are becoming rare, but that does not enabled Hollywood to make up
But, that doesn't mean that we should continue making films about the same subject; the Holocaust. Some films can lighten the mood of the Holocaust by adding light situational under tones such as romance. By adding something along the lines of this to the existing horrific mass murder murdering scenes the Audience will be touched by the couple kissing in the middle of all of the chaos, while learning more about the Holocaust. Maybe if the Holocaust films were told by the perspective of the imprisoned Jew then the films would be worth the making. But that will never happen since the point of view is too horrific for the innocent public
