How is Alex Steiner conflicted with regard to Nazi beliefs?

Alex is Rudy's father, a tailor who does not hate the Jews, but was somewhat relieved when the Jewish tailors competing with him were driven out of town. He is conflicted in this way. Alex refuses to let Rudy be inducted into an Army training academy and is punished with conscription. After the war, Alex, who has lost his entire family in a bombing raid, reopens his store and is kept company by Liesel.
