As a program of mass murder or genocide, the Holocaust concluded with the end of the Second World War in 1945. In terms of making a philosophical observation, general consensus has made the conclusion that the episode is the epitome of evil. While the events themselves are over, the ramifications and issues raised by the Holocaust continue to be debated to the present day.
The Holocaust or the Nazi's so-called "Final Solution" of exterminating Jews and other populations the regime considered undesirable reached a conclusion when the Allied Forces conquered German territory and took over the camps in the spring of 1945.
The episode demonstrated the human capacity for evil deeds and how these may be embodied and reinforced by social and political structures. Many issues, such as restoration of property stolen by the Nazis, continue to remain unresolved in the 21st century.
