I despise anyone who becomes a soldier of their own free will. The moment you enlist, you accept that you could be obliged to kill, and that you will have no control over whether that killing will be justified.
In other words, you accept the possibility that you could become a murderer.
Seems like you went to the more touristy places. Or Munich. Or a touristy place in Munich. They tend to be a little brusque and unfriendly there… It really pays off to look for places on Maps which are highly rated and a little off the beaten path. Some real gems there. I could name a few restaurants in Berlin which serve awesome German (!= Bavarian!) food that isn’t repetitive.
