When I read Eliezer's original post, my moral intuition crashed. I was confused, and suspected something was wrong with either the question, or with me.

Are you really suggesting that choosing to not commit to an answer immediately but to instead think about it and explore the scenario for a while was the wrong answer? If the scenario were instead "choose TORTURE or SPECKS within the next N seconds or get one at random," and was real, not a thought experiment, then see Eliezer's point: inaction is an action.
