The butterfly effect refers to divergent chaotic systems. Chaos in math isn't the layman's chaos. It doesn't mean wild. It only means there is no closed form mathematical solution. For example stepping on a butterfly can't affect the weather such that the moon would crash into the Earth.

Bumping into Hitler's parents wouldn't necessarily change anything. You have to do something drastic such that he was conceived days to weeks apart such that the sperm was completely different. Even a minor delay wouldn't affect it because the sperm that fertilizes an egg isn't random. There are selection hurdles in mobility that the sperm passes such that the most "fit" is likely the one that fertilizes the egg.

Don't like your highschool bully, just bump into their parents back in time. Or you know, "bump" ( ͡° ͜ʖ ͡°) into their parents

Forcing your high school bully to call you daddy is one hell of a power move

B. F. Skinner would like a word

For twenty-five hundred years people have been preoccupied with feelings and mental life, but only recently has any interest been shown in a more precise analysis of the role of the environment. Ignorance of that role led in the first place to mental fictions, and it has been perpetuated by the explanatory practices to which they gave rise.

on a side note...

Important Note: In order to marry, Alois and Klara had to obtain a dispensation from the Church due to their close familial ties. This highlights the fact that they were indeed related and their marriage was considered unusual for the time.

If the same geopolitical environment still led to World War II but with a different German leader then the outcome of the war could very well have ended differently.

Leading up to major invasions like D-Day in Normandy and the invasion of Sicily the allies implemented major deceptions to confuse the Germans. Despite some senior leadership recognizing at least some aspects of those deceptions, Hitler himself fell for them pretty thoroughly and ordered troop movements that reduced German defenses where the attacks took place, and delayed moving them back because he still believed the deceptions were real. There are other examples of poor decisions by Hitler throughout the course of the war that proved helpful for the allies as well.

If Germany had a more qualified military leader running things then events like the Normandy D-Day invasion could have had a very different outcome. If the Germans had the Normandy beaches better defended then that invasion could very well have failed. And if that happened then there’s a good chance Germany could have won the war.

That's not how time works. If you go back in time and kill Hitler Hitler already happened in your timeline so he's going to happen again. You can't change things that already happened in your past.

yeah. you, your parents, your grandparents, all your people, GONE. never happened. different versions of same still happen, possibly even happy and flourishing. love that for them. Also Hitler still happened, under a different name.

Believe it or not... You've got Hitler Squared now 🤷‍♂️

I read a short story... I don't remember the name of it... Anyway the guy goes back in time and kills Hitler, only to discover upon his return that everything was worse. So he went back and stopped himself.

make his dad pull out

LOL

That's not how any of this works. Not-quite-Hitler would still be exposed to the same influences and grow up to be the same person.
