Such brutality was not accidental. The SS guards would often force prisoners – exhausted from hours of hard labour without sufficient food and water – to race up the stairs carrying blocks of stone. Those who survived the ordeal would often be placed in a line-up at the edge of a cliff known as "The Parachutists Wall" (). At gun-point each prisoner would have the option of being shot or pushing the prisoner in front of him off the cliff. Other common methods of extermination of prisoners who were either sick, unfit for further labour or as a means of collective responsibility or after escape attempts included beating the prisoners to death by the SS guards and Kapos, starving to death in bunkers, hangings and mass shootings. Inmates were also simply beaten to death, as in the case of Viennese Jew Adolf Fruchthändler.
