Adolf Hitler: His Family, Childhood and Youth

One of my biggest questions is what made Adolf Hitler to be a monster, killing 6 million Jews? One day I visited the campus library and found two books on Hitler, a thick one and a thin one. I remembered the question and I picked up the thin book.

These are what the book told me about Adolf Hitler.

• Seeing the photograph of his infancy, Adolf Hitler was a sweet baby. If you were able to go back to the past and meet him as a toddler, I don't think you'll have enough courage to slaughter and kill the tiny future-beast in cold blood.
  
• As a child, he never felt the true love of his father, Alois. He used to get harsh treatment from the father.
• He loved his mother, Klara. She always find ways to protect her children from the anger of his husband.
• He was a brilliant student in primary school and junior school. But he performed very poorly in senior high school.
• He was a quiet boy and a loner, but he loved to play Americans and Indians with his peers. A preparation for becoming a Fuehrer? Mmm, I dunno.
  
• He was a dreamer, an acute one. He aspired to be an architect but failed to enter the Academy in architecht because he was considered not having enough aptitute for the discipline. He prentended that he were an architect student, spending his time drawing and wandering in Vienna.
  
• He hated the city planning of Vienna. He wanted to destroy it all one day and rebuild it according to his own design. He truly had that chance when he came to power.
• He was very lazy, so lazy that he always wake up late in the morning all his life.
• He lost his savings due to poor financial management and he lived as a tramp for quite a time. There were many mornings when he went the five or six clocks to beg for a soup from a convent which situated only a few doors from the apartment where he resided as a young gentlemen two years before.
• Another charachteristic of the later Hitler already discernible in childhood and youth was his difficulty in making long-range decisions. As a boy he was unable to accept the fact thata series of small decisions, made or postponed, ultimately amounted to a major decision. (p. 155)
• He was highly influenced by a cheap racist magazine called Ostara.
• None of his teachers posed very strong influence on him.

Apparently my question above has not found its sufficient answer from the book. Maybe I should borrow and read the thick one. But what I learn quiet a lot from the book, two are as as follow.

• Never underestimate anyone, be he/she your student, your pupil, your maid servant, your driver, anything. You'll never know what he/she will become and you'll never know what he/she will do to you when you are already old and they are in their peak performance.
• Don't underestimate the potential of influence your actions and speeches have to others. They may be better or worse individuals. Make sure you choose the right one.
