Well yeah, that's what the eternal recurrence is. Literally all of the universe is in an infinite loop. When I said my unconscious mind may have played a role in when I got my cigarettes, that's because I'm someone who can actually remember we're in a loop so I actually have the ability to change my actions. Everyone else is just doing the same shit they always have without a chance to escape unless they start to remember events in their own life before they happen. So no, it's extremely unlikely the jew who delivered baby Hitler would ever do anything differently. Although if he did, we wouldn't exist. Think about how unlikely it is for you to be alive. All of history has to play out in an extremely specific pattern in order for all of your ancestors to meet and mate at the correct time. So perhaps every time someone does a different action, a whole other sequence of events on Earth happen, completely different from the one we recognize. It's just that if that did happen, we wouldn't be born and we would never experience it. So perhaps instead of the universe being in a simple loop, maybe the loop is very complex with every single possible reality playing out between the time you die and the time you're born again. You're not conscious of time during such a state of non-existence, so literally any amount of time could play out and it would still feel like an instant.
Just to clarify, I'm not saying every possible sequence of events is sure to happen, I'm just saying that it's a possibility. It could also be possible that only one sequence of events has ever existed and nothing varies in the slightest every time the universe plays out.
