It was no exaggeration to say that Heidi's humanitarian efforts had a monumental payoff for the German Reich, its wounded veterans, and their families. Less deaths meant fewer orphans and widows. And those that were created were well taken care of by the financial support that Heidi had put in place for them via her nationwide charity.
The result of these selfless acts were widespread, and well known, in part because of the influence the von Zehntner family had over the press, but also because good deeds done for their sake alone were a rarity in this world.
Altruism was a concept that existed in theory only. It was an idea of what humanity could be, but in reality would never be. Any time any human ever did something that could be perceived as selfless there was always some ulterior motive.
