That doesn't seem like that much of a dilemma, because the consequences of inaction do not clearly compete morally. It's possible to list endless hypotheticals, but the end result will always be this:
The only rational way to have absolute morals (that means you will never do anything that violates these principles), is to be able to guarantee that these morals will never compete. Otherwise when absolutes meet, you're going to have a problem. People are going to suffer, they are going to die, and they are going to be innocent (eg: collateral damage).
