There is absolutely no chance a man of his position, career history, and political alliances would ever have let shosanna go/live. No fucking way. After going to all that effort to locate and eliminate the remaining Jewish dairy farmer family. They would not have left any survivors.
shareI can see both sides of "he never would" or "he would and it fits him" so ill argue the latter for fun
He loves the hunt. hes a "hawk" and the jews are "rats". hed already won. hed seen through the farmers lies, hes found them and killed her whole family. Tracking her down alter would only show what a great hunter he was. and save more fun for another day.
This is exactly how I took it. He seemed like he was looking forward to hunting her. It was fun for him.
shareHed proven himself once again. Hey may have gotten Joy from this job in particular, but really Hans was someone who excelled at whatever they did, a career perfectionist. He wold have excelled equally at organizing trash disposal for the nazis. so to him he didnt lost anything to let her go.
Tracking her down again would only stroke his ego and be fun for another day.
