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 that point you pretty much got a whole day to go and rescue the guy, assuming trolley is traveling around 40-50mph

The trolly might not have but your choice did.

Couldnt the person tied down escape by the time the trolley comes?

Trolley of Theseus!

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.

Can someone please stop the maniac who keeps tying all these people to trollie tracks?

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.

Easy task: Pull the lever, jump into car, rescue the man, far away. Then burn down the trolley and everyone involved in your misery.

If you take a thought experiment and replace all the thought with meaningless garbage, is it still a thought experiment?

How does one replace the trolley's trucks (wheels and axles) without stopping it over 1000 mi?

So much work when all I want to do is run over people with a trolley.

Like the axe in John Dies at the End!

Was the trolley build by NEWAG?

You're definitely not guilty.
