Except that somewhere down that chain someone is almost certainly going to choose to kill people, so by passing the trolley on down to them you’re responsible for killing a lot more than if you ended it right now.
And since every rational person down the line is going to think that, they’ll all be itching to pull the “kill” lever first chance they get. So you know that you need to pull the kill lever immediately to minimize the number of deaths.
Only the person pulling the lever is responsible for his/her action though. There is a difference between passively passing on and actively murder someone
If I hand a machete to Jason Voorhees I think I’m at least partly responsible for the people he hits with it. I know what he’s going to do with that thing.
Except you’re not passing a machete to Jason Voorhees. That would be “double it and pass it to the next person who you know is going to pull the lever.”
You’re passing a machete to the next person in line. You don’t know who that is. They may or may not pass the machete down the line. Considering I would not expect a person chosen at random to kill someone when handed a machete, it seems unethical for me to kill someone with a machete just to prevent handing it to someone else.
If we all collectively agree to just pass it on, then either:
It’s infinite, and it just passes on forever, or…
It’s not infinite and somebody at the end has no choice, in which case nobody in charge of a lever has killed anyone
So yeah, I say pass it on.

Dentological ethics: you have a duty to not murder people, so you don’t pull the lever
Utilitarian ethics: pulling the lever will kill less people

I know Jason is somewhere down that line I’m handing the machete off to. And the farther down the line he is the more people he’s going to kill.
If it’s infinite, you’d basically be gambling that no evil person exists.
