The Boy in the Striped Pajamas Chapter 6

Maria is a maid for the family. Back when she was younger, Father took care of her and her mother, saving her life. He took her under his wing and paid for all the expenses for her mother's medical bills and funeral. This tells me that Father is actually really caring deep, deep inside his soul. This is very different from how Father acts now. He's now helping to torture people when back then he was saving them.
