Erich, might be of interest for you, but the British military cemetary my great grandfather is buried in (in France) also had several German soldiers intered there for many years.
I think for many people back then who set up the cemetaries, they thought that the whole war was insanity, and whomever was killed, it was just another poor soul caught up in events.
That is how I believe it is in most wars. You have take time to remember the dead and honor them in every way possible. All fallen soldiers have one thing in common. They are soldiers and should be remembered for there duty and sacrifice.
To all soldiers from past wars, may you never be forgotten.
