"In the storied history of our corps, no adversary honored us more in battle than the Japanese soldier. He was a formidable adversary who though suffering enormous privations and misery that would have rocked lesser men, never lacked nerve, dedication or determination in the cause he fought and died for....country and duty. His toughness made our corps hard and worthy."
The Japanese have been hit hard, brought to their knees and they're hurting but they're by far not beaten. They will survive and they will go on...it's part of their heritage and in their nature.
the former implies nothing worthwhile came of it, while the latter is the very opposite. In the Atom goes to Mars episode, the officer (Ketchup) redeemed himself from his treachery in sabotaging Atom's umbilical cord or giving him a nearly empty energy cassette by leaping into a vehicle and charging straight into the enemy. Atom could not endure this act, because to him, the man intended to die or was heedless of the overwhelming odds. But because of this act, the tide turned against the enemy. Thus, though he may have been attempting suicide, he also because he was not worried about his own death, was that much more effective in his attack. If he had just run out there unarmed and yelled "shoot me! I cannot bear to live with the guilt of my treachery!" that would be throwing his life away, though it was obvious that he deserved death.
