I tend to feel that is the general answer, but that at some (arbitrary) level of absurd disparity of outcome, it becomes morally imperative to act. Like that 5-to-1 standard trolley problem is a hard question for me to answer, and on different days, I pick different answers. Probably "do nothing" most days. But if you made it 50,000,000-to-1, it is not a hard problem any more. Somewhere in between those two is "the line" where the fact that you are becoming a murderer is outweighed by the value of the life you saved. Yes, if I could be certain that I could save 50,000,000 lives by murdering someone, I think it would be a moral imperative to do so. That wouldn't change the moral evil of murder, it just outweighs it. I think. Don't ask what I'd do "in real life", I won't know until it happens (which I pray it will not)
