While it is true that he may have thought and believed that what he was fighting for was right, the fact to the matter was that he was not. What he was fighting for was U.S. imperialism, working for the fascists(Christians in this case) and dying for the exploiters and oppressors...

"While it is possible, and correct, to hate the way in which those who become “the troops” have been systematically lied to in regard to what their mission is all about, and are cynically used by the ruling class—often ending up killed, or more often terribly maimed and wrecked, mentally as well as physically in a large number of cases—there can be no support for these troops, because what they are conditioned, shaped, and trained to do, and what they are actually doing, is carrying out war crimes and crimes against humanity on a massive scale, all in the service of imperialism. They are not “serving their country”—except insofar as “their country” refers to the imperialist state. Nor still less are they “protecting the rights” of the people of the country. They are acting as the massively destructive and murderous forces of invasion and occupation, they are serving the imperialist system and the ruling class of that system, which lures and then organizes and trains and then deploys them in the pursuit of its interests, in opposition to interests of, and to the great detriment of, the masses of people throughout the world who are the target of this imperialist system." - from Revolution #119

And in standing in oppossition to the way, yet giving support for the soldiers, you know, those signs that say "Support the Troops, Not the War" is also not a correct way to think, it is the same thing as saying "your against the rape, but not the rapist..."Revolution #119)

"All men must die, but death can vary
in its significance. The ancient Chinese
writer Szum Chien said, "Though death
befalls all men alike, it may be weightier
than Mount Tai or lighter than a feather."
To die for the people is weightier than
Mount Tai, but to work for the fascists and
die for the exploiters and oppressor is
lighter than a feather."
- Mao Tsetung
