In fact the film makes a big deal about the lingering torment of being laughed at. A Jewish roommate of Hitler’s, Schlomo Herzl, is forever teasing the young artist. However he also takes him under his wing and treats him like a son, and it’s clear the humour is affectionate and for Hitler’s own good. Hitler simply cannot take being laughed at or looked down to by a Jew though and he finds Schlomo’s care for him repugnant. Nevertheless he exploits it. He accepts Schlomo’s help to prepare him for his interview and entry exam. He lets Schlomo sell his post cards for him so that he can pay rent. He treats him like a slave and then sets about robbing him of his young love. Evidence of a later political pragmatism perhaps?
