Right, but choosing the lesser of two evils is simple enough. That's not the kind of dilemma I'm talking about. I'm asking whether or not there are wholly undecidable moral problems. Choosing between one evil and a lesser evil is no more difficult than choosing between an evil and a good.

But if you're saying that in any hypothetical choice, we could always find something significant and decisive, then this is good evidence for the impossibility of moral dilemmas.
