You **might **have “a lot” of time (or you might not) - but the choice to be made is unchanged. No one is accused of murder (legally or morally) because the child dies in removing the tube - not if time is short (acute tubal rupture pending - emergency surgery required), nor if it is lengthy (early detection).
The time available to exercise judgment and/or seek counsel is only ever the time prior to which one must choose an action (eg. to flip a lever, or leave it as it is, to have surgery or not). The trolley problem (and ectopic pregnancy) both set a hard limit on that time frame. Whether it is short or long is irrelevant. Prudence requires doing what can be done within that timeframe. How fruitless to demand more time than exists - when the time has passed, the judgement is made for us. Our obligation is to use our best judgement in the time available for forming judgements.
It seems you are arguing it is immoral to “flip the lever” (or submit to surgery) if the circumstances are such as to require that decision to be made quickly (say, within seconds or minutes), but it is moral to flip the lever (or undergo the surgery) if the circumstances are such as to allow one to “take a lot of time to take counsel” and then decide to flip the lever. But previously, you claimed the act of flipping the lever was wrong because it was intentional killing. Now you say it is wrong because we did not think for longer than the available time for thinking. I think you need to think again Tom.
