Great article. I agree it is much harder to have moral courage than physical courage and I think this has started to be recognised with a recent film about Desmond Doss (hacksaw ridge) who refused to carry a gun, was labelled a coward yet saved hundreds under the worst conditions. I also know from first hand experience that details of Hugh Clowers Thompson jr actions during the My Lai massacre are taught at British Officer courses as examples of moral courage to be admired.
You have to be a special kind of individual to exhibit that kind of courage and I don’t think any of us know if we have it in us until we are put in that position.
