The first case is straight forward (to me :-) kill the one, save the six. The second case is a bit more morally difficult. I would have to save the one and hope other organs or possibilities come along for the six (I disagree with the future, "god" situation that says the others would die). I would not be able to "harvest" organs by allowing someone to die whom I could have saved straight out; that would be my omelas situation.
