In all programming languages that I know, integers have a maximum number. E.g., in C that'd be 2,147,483,647. After that, you would run into an overflow, resulting in either...
a crash (train stops, no more deaths),
death count suddenly turns negative (all people previously killed are suddenly alive again and even new people are generated out of nowhere) - until we reach the next overflow when people disappear and start dying again
or - if it's an unsigned integer - death count resets everytime we reach the maximum limit
So compared to option 2, we have a chance of stopping the death count. And even if the train keeps running, we have essentially option 2 but the same people only die very rarely. If we assume a cycle of 1 death per second and an integer boundary of 2,147,483,647, that's just one death every 68 years per person involved. Seems more fair to me compared to 100 people constantly dying over and over again.
Or is it like a Y2K death trolly and when the overflow happens the universe doesn't catch the exception and things get weird. Like suddenly any number can be divided by 0.
At the universities I went to, Calc 2 was integration, sequences and series, then Calc 3 was multivariable. They really pack all the harder parts into 2.
I found linear algebra super hard until I learned it a second and then third time, from different angles. I found it harder to understand when it was taught in a pure maths context, but coming at it from the applied side made me go "oh, so that's why that's like that"
Arguably these are different amounts of bad even before considering this: We generally consider existing preferable to non-existence to some extent when suffering isnt taken into account, consider that if you murder someone quickly and painlessly in their sleep without waking them, they dont really themselves suffer from it, but people will still find you to be a murderer, and would object to the idea that you might do it to them. In the top example, killing the people actually kills them, but in the lower example, it arguably doesnt, because the experiences of the people involved never actually cease, therefore, the lower path seems to me to be preferable because you supposedly get equivalent amounts of "suffering", but different amounts of time that people spend in non-existence.
Well their heads aren't on the tracks and they're immortal, I bet we could rig some kind of device to make them total praplegics and then work on a direct neural interface so they can use computers while they lay there endlessly having their bodies painlessly trisected.
Allegedly it isn't a place where you are tortured, but instead a state of permanent depression from being cut off from God. Just the former is easier for pop culture to portray.
Also, Option 1 would essentially mean the end of the human race. Assuming the rate of killing is faster than the birth rate it would mean everyone dies soon
