At 28 minutes in: Fritz Haber breaks apart nitrogen from thin air, for the common good of feeding Germany and the world, and makes it possible to sustain 7 billion+ people with “bread-from-the-air” agriculture.
Then he breaks apart nitrogen, to annihilate enemy lines in WWI, for the common good of Germany.
Then Hitler uses Haber’s technology to annihilate Haber’s own Jewish family and friends in the gas chambers, in WWII, for the common good of Germany.
We are a powerful force whether we think we are or we think we are not. We make change when we realize this. We can choose to use our power to give life or to make death. What comes around will go around, because we are all one. We all want the best for The Common Good. Our paths diverge because we have different definitions of The Common Good.
