Philosophical question

The late Norman Schwarzopf, quoted in The Daily Beast:

“The truth of the matter is that you always know the right thing to do. The hard part is doing it.”

Is that true?  I don’t know.  Is wondering whether it’s true just a way to evade of “doing it”?

from wikipedia, Vietnam 1970:

As the wounded man flailed in agony, the soldiers around him feared that he would set off another mine. Schwarzkopf, also wounded by the explosion, crawled across the minefield to the wounded man and held him down (using a “pinning” technique from his wrestling days at West Point) so another could splint his shattered leg. One soldier stepped away to break a branch from a nearby tree to make the splint. In doing so, he too hit a mine, which killed him and the two men closest to him, and blew an arm and a leg off Schwarzkopf’s artillery liaison officer. Eventually, Schwarzkopf led his surviving men to safety, by ordering the division engineers to mark the locations of the mines with shaving cream.
