Heroes are not created equal. Most people recognize the name Sully Sullenberger, but far fewer can tell you what Alan Turing did during World War II.
Fewer still could tell you that Turing was chemically castrated because he was gay, and committed suicide shortly thereafter. But thanks for bringing one of the most horrifying wars in history to an abrupt end, I guess?
Society isn’t always kind to its heroes. We ask for an ill-defined yet idealized sort of perfection, and when our heroes fall short, we make sure they fall twice as hard.
Some might write this phenomenon off as a minor inconvenience for the rich, successful or famous, but times have changed. The human costs of war pale in comparison to the battles humanity will face in the years to come.
