You don’t suffer after you’re dead. Being reincarnated and killed infinite times is infinitely worse than being killed once. If each trolley kills at the same rate, the actual amount of created suffering should be comparable, but I’d argue that since the infinite people don’t revive, we can assume that the trolley is replacing their normal deaths. This means that the suffering they would experience from dying normally never happens and the infinite people option actually creates less suffering overall.
