Not caring to look myself, did this man's father raise him?
My father certainly influenced my outlook on many aspects of life when he raised me. I am of course responsible for my own actions, and it is everyone's responsibility to rise above the shortcomings of their parents, but to ignore the role a parent plays in their child's development is just silly.
For example, my father is an evangelical christian. I am not. Realizing that my father is gives a window, however murky, into my development and provides context for many of my beliefs and convictions.
Noting the similarities between the father and the son gives us potential insight into the [lack of] moral development of the son.
Not too much, except for the first eleven years, Albert Speer Jr. was born in 1934. In 1945 his father got sentenced to 20 years in prison and served until 1966, mostly in Spandau. Wikipedia states that he wrote many letters to his children from prison but "found himself unable to re-establish his relationship with his children, even with his son Albert".
>you strongly implied that his father being a Nazi somehow influenced his own behavior
A lot of psychological traits of a person form in early childhood. Do you think his childhood environment was very conductive to development of an unconditional empathy and other humanistic feelings toward other human beings, especially ones of non-"Aryan race"?
