There were "baddies" on every side, but one side was the morally "rightest" - the ones fighting for their freedom and independence (aka North Vietnam, the communists). All the rest were colonial powers trying to force a corrupt puppet state which had nothing positive going for it other than being against the communists. So, motives-wise for war crimes, I'd take "freedom (not individual, for the country and peoples) and independence" over any of the reasons why France, the US or China were there. Still war crimes, still needed to be tried, but nobody did that anyways in that war, so all else being equal the motives "win".
