Answer:
The man in the quote seems to be a caring and sympathetic man who wanted to save as many people as possible from being taken to the death chamber.
Step-by-step explanation:
Elie Wiesel's memoir "Night" revolves around his along with his Jewish people's torturous time during the German Nazi's discriminatory regime under Hitler. This event where a mass genocide of the Jews would later become one of the most horrendous acts of discrimination in the world's history.
The given description is that of the man who was interrogating them on their arrival at the Auschwitz concentration camp. Elie revealed that he was an inmate and he wanted them to lie about their age so that they are not 'discarded' and 'killed'. The use of the words "weary and warm" suggests that the inmate knows what he's doing and wanted to save them from the death chamber. This metaphorical presentation of the man through his voice shows the man may be sympathetic and also cares for the new arrivals, and would want to save or keep alive as many people as he possibly can.
