I just want to say thanks to everyone for your comments and I now realize the obvious flaw of incorporating any extremely personal connection into a mathematical morality calculation. Because, as BlueSun pointed out that causes problems on whatever scale of pain involved.
if you were faced with your Option 1: Save 400 Lives or Option 2: Save 500 Lives with 90% probability, would you seriously take option 2 if your loved ones were included in the 400? I wouldn’t. Faced with statistical people I’d take option 2 every time. But make Option 1: Save 3 lives and those three lives are your kids or option 2: Save 500 statistical lives with 90% probability I don’t think I’d hesitate to pick my kids.
I also learned not to grandstand on morality questions. Sorry, about the “would you do it? really?” argument, I won’t do that again.
However, I still fall on the side of the dust specks after rethinking the issue, but due to the reasoning that the 3^^^3 individuals would probably be willing to suffer the dust specks to save someone from torture, while the tortured person wouldn’t likely be willing to be tortured to save others from dust specks.
I am basing my reasoning on the probable preferences of those involved, so my answer would depend on the feelings of the people to being dust specked/tortured.
I’m not entirely clear what exactly you are asking with number 1: are you just asking 1.6 seconds of torture vs. 3^^^3/ 1 billion dust specks? If so, I’m essentially indifferent, it seems like both are fairly inconsequential as long as the torture only causes pain for the 1.6 seconds.
For number 2, a billion dust specks would probably get to be fairly noticeable in succession, so I’d prefer to get 1.6 seconds of torture over with, because that isn’t really enough time for it actually to really be torturous (depending on what exactly that torture was) rather than deal with a constant annoyance.
