> Almost every person beneath a capitalist system has a material interest in wealth. That does not translate to intent to seize it.If intent does not matter, only interest, then there is no war crime in bombing boats.

That's a different topic, legislative intent is different from criminal intent, the latter does not change the fact of wrongdoing, only the severity of it. Bombing sailors in a wreckage situation is either a war crime or gross military incompetence which may lead to court-martial. This together with interest-as-motive are decided based on facts and logic, not philosophy - these arguments support my view, not yours.
