I read the Einstein biography. Highly recommended. But to the parents point, I came way think Einstein was a huge asshole, especially given his pop culture representation as a kindly old grandfather type.
Probably every human being looks like a huge asshole if you put their entire life under a microscope. Even Mother Teresa did some giant asshole things if I remember. You're just not aware what a huge asshole you are because someone hasn't written a very good biography of your life from a perspective different from yours (or you havent lived long enough)
