Heads up, Hitler's mom died of breast cancer when he was young. If you're going to seduce her, you should be emotionally prepared for the consequences.
Eva: Adolf, why are you destroying everything?
Adolf: My father is a time traveler from the future and he left me. So I make sure he will not exist.
Eva: From the future? So he could also be our son? laughs
Adolf: takes the gun
If you think about it, there are on average 30 to 80 million sperm in a typical ejaculation. So I'd find Hitler's dad on the street, bump into him and jiggle his nuts a bit. Surely that'd be enough to change history.
Adopt baby Hitler and raise him in a way that would not give rise to the kinds of feelings and ideologies that could lead him down the path of ethno-nationalsim.
Plot point: hero person goes back in time to kill Hitler, but finds they have to fight off a bunch of other time travelers from different points in the future bc everyone wants the kill for themselves. Hitler still gets away.
Just finished binging the 12 Monkeys TV show, thats just variations on an oops loop. If you seduce Hitlers mom you'll just end up being the father figure he never met. If you strand him in Nepal then either Hitler or any Austrian who witnesses you doing the timey-wimey dance will just blame an international cabal of time traveling Jews for it.
Starting a relationship with Hitlers mom will eventually end in heartbreak when she dies from breast cancer after several painful experimental treatments. I'd rather kill a baby.
You would have to deal with the social, cultural, and economic factors which lead to the rise of a person like him to power. Simply killing one person in the grand calculus of the social factors at play would likely do very little to stop WWII and it's atrocities. Changing him could have lead to a more radical or desensitized power hierarchy that could have been much worse.
Preempt the war by taking back info on the atomic bomb to Roosevelt so that it could be utilized earlier and more effectively as a deterrent.
Gotta love the heteronormativity on this post. Why fuck the mother? Why not go back in time and fuck Hitler and make him fall in love with me? All hail homo-hitler!
