I wanna know your answer so I'll be boring and direct.
Who would you save from death if you could, 1 toddler or 100 in-vitro embryos? "Magic" scenario where you have to choose one or the other.
Honestly don't even respond if you don't want to I'm just annoyed so many people miss the point of the trolley problem and try to talk about the trolley. It's just to make you evaluate your choice! The trolley isn't the important part!
You already have my answer: try to derail tram in order to save both. If I fail, I fail. Knowing that I tried to save 101 people is all that matters because in the end the tram operator will be the one sued to make the family(ies) whole.
You are being obtuse. Don't answer if you aren't going to give a valid answer... It is just wasted effort. There is no real trolley. You aren't being heroic by not answering this question with a valid answer.
