Who was the kapo who had bouts of madness?

The kapo known for having bouts of madness was known as "Mengele's madman," a reference to the infamous Dr. Josef Mengele, who conducted inhumane experiments at Auschwitz. This kapo, whose name is not universally recognized, exhibited erratic behavior, likely due to the psychological toll of the environment and the moral compromises made in their role. Such individuals often struggled with the dehumanizing conditions of the camps, leading to severe mental health issues.
