The butterfly effects would add up and and any zygote formed would not be the hitler-as-we-know anymore, since it would be a different combination of sperm and eggs.
Who needs guns when you got a time machine? Don’t like your highschool bully, just bump into their parents back in time. Or you know, “bump” ( ͡° ͜ʖ ͡°) into their parents.
Dude, don’t you think we tried that? The first time we got Schickelcutlerstalin for some reason who killed everyone with his out off-control biological weapons. Then for some fucking reason we got a fucking snake hitler!
And now we are all out of time-travel juice and locked down in a reality where hitler lived AND an orange is also hitler. Well, I had a little bit left,but a giant testicle came along, kicked me in my testicles,shouted “you want fucking Mother Theresa torturing everyone to death” and disappeared.
Now I am stuck here. Fuck.
