In that case, no, and you’re not responsible anymore. Those people working on switching out the trolley parts had every available opportunity to fully stop the trolley, more-so than you. You diverted it to save a life immediately, that crew maintaining this Trolley of Death are the real murderers.
They couldn't have replaced the trolley parts had you not sent it.
My favorite trolley experiment is still the dad presenting it to the little kid, who proceeded to think outside the box and moved the one person to the other track with the second. And then ran them both over.
At the very least, if you throw the switch you then have a thousand miles to figure out a way to save them. Or to put the other person on the same track, depending on your style.
After a few miles down the tracks, I won't see or hear the trolley anymore, therefore i can not be certain it even exists anymore. It may have run over someone, it may have derailed, it may have exploded, it may have run out of fuel and stopped, a black hole might have opened up in its path and swallowed it whole.
Problems like this aren't unsolved, it's just that these problems have different answers depending on the context.
Is it the same trolley that kills the man? Yes because repairing the trolley doesn't change it's name.
Is it the same trolley that kills the man? No because it is physically not the same trolley.
Humans divide their cells until the original cells are gone. Are they a different person?
Yes they are.
No they aren't.
Depends on what you're measuring or what problem you're trying to solve. But both perspectives are simultaneously true. Wait until you get to math and find out there's different lengths of infinity. It's all tools used to solve problems.
This is exactly why these trolley problems don't work. When we strip away all context and ask simplified questions the nuance disappears and the question becomes almost meaningless.
That's why I think these are mostly nonsense. These types of questions aren't philosophical, they're psychological. They don't teach anything, they just test what you value, and they're not the best types of questions for doing that either.
In that people have been creating their own trolley problem memes to illustrate either how they think Biden is just as bad as Trump or that despite Biden being imperfect, he's still the ethical "flip of the switch".
I love the downvotes though on a simple question. It's ironically unencumbering to be projected onto without any context to base one's disagreement or anger.
