Moishe the Beadle, as described in the book "Night" by Elie Wiesel, exhibits this behavior because he has witnessed and experienced unimaginable horrors during his deportation and imprisonment by the Nazis. Moishe has lived through the Holocaust, an event that involved severe persecution and mass murder of Jews, and has managed to escape and return to his hometown. However, the trauma from his experiences has deeply affected him, leading him to become withdrawn and avoid contact with others. He carries the burden of what he has seen and endured, causing him to become introverted and disconnected from those around him. The constant state of fear, pain, and suffering has left Moishe deeply traumatized, resulting in his hunched posture, lowered gaze, and avoidance of interaction with others.
