Spatial, your idea assumes everyone agrees with you, and if they do, you'll have managed to get the entire humanity tied on a train track.
Such a task is barely even possible in all honesty.
Here is what will actually happen. After your turn, when you run to the next person about to pull the lever (me, BT, TC, anyone else) to tell them about your masterful idea, they will look at you like you're mad and pull the lever, and then the only thing you will have accomplished is doubling your body count.
From the basic model, there is no interaction with the previous subject/subjects.
The worse case scenario is that your idea somehow takes root until someone with sense pulls the lever, in which case, depending on how effective your stupidity was, you'll have managed to exponentially increase your kill count, possibly surpassing the likes of chairman Mao. And then in the exceedingly unlikely worst case scenario that you manage to somehow achieve what you wanted, all 8 billion of us are waiting to be run over by a train, and you'll be awarded humanity's last and greatest Darwin award.
Setting aside Spatial's retarded idea that could result in the extermination of humanity, what I find difficult to evaluate about the problem is whether or not I'd have the nerve to pull the lever. It feels easier to pass the responsibility on. However, given the rapidly increasing body count, it's the right thing to do. So, I'd do it.
As I mentioned to Nathan in a previous post, the rules are unclear, and if everyone passing means death for all anyway then it would make sense to kill the first person. That was never mentioned.
My model suggests the game ends when there's no more bodies for doubling, which ends at 33 people. If that rule is implemented, then I got it right. It wasn't, nor was the rule of imminent death for all if 33 people pass. The game in this case should end, because it cannot double anymore, and no one decided to make a kill.
If 33 people passing means the game can no longer continue, then not a single soul died. On an interplanetary scale the world who does this would be more advanced than one who killed even the first person.
When presented with this, a normal person would pass on it. In real life if you handed someone a pistol and asked them to kill some random person or else 2 others more will die, they'll most likely pass up on it anyway.
A very small percentage of people have the nerve to kill someone, and an even smaller percentage has the nerve to kill someone without it haunting them for life.
