Well the point of the movie was whether Col. Kurtz was sane and everyone else trying to silence him was nuts.
LOL you beat me by a few seconds in pointing out the major theme of the entire movie.
But by any true warrior standard (i.e. Genghis Khan) Colonel Kurtz was the sane one, he was charged with waging war on an enemy — Kurtz was pissed off that his men were dying because the politicians wanted the US to wage war with The Marquess of Queensberry rules for fighting and the enemy was fighting with no rules. In the movie, Kurtz was very clear on what the mission was — It was the politicians that kept yanking at his leash, he finally bit the owner and took matters into his own hands.
Best quote from that movie: “charging a man with murder in this place was like handing out speeding tickets in the Indy 500.” Second best quote is: “We train young men to drop fire on people, but their commanders won’t allow them to write “f%$#” on their airplanes because it’s obscene!
“War is the remedy that our enemies have chosen, and I say let us give them all they want.” ~ General William Tecumseh Sherman.
Essentially, if you are not fighting to win - quit!
