If we killed hitler we would have more competent nazi and possibly still third reich over here but no Poland and I am selfish I wanna exist ya know
Best person would be trump as it is recent enough to not suddenly cease to exist due to various butterfly effects, still pretty risky though. All of people that died by accidents between trump election and today would be from different, new set. You can calculate probability even based on average yearly accidents.
God I shudder to think what if u killed Julius Caesar. We would be like unrecognisable due to all branching out possibilities over the years. Real quantum parallel worlds shit
Well now we're getting really speculative. But probably what we have now but with something like undember or under and duoly or duoer in the 11 and 12 month positions.
Might be able to avoid The Nazis and The Bolsheviks gaining power altogether by going to 1970, buying a year's worth of McDonald's food, and delivering it to Taft in 1911. He's so damn fat he got stuck in the tub in The White House. He'll happily eat that shit and hopefully die before the 1912 election, allowing Teddy to have his third and fourth term. In a head to head race between Roosevelt and Wilson, Wilson doesn't have a prayer of winning.
The good news is that if someone went back and changed the past, then events would transpire such that they never had to go back in time for that reason, and so they wouldn't., i.e. nothing would change. Not unless the whole exercise spins only the time traveler off into their own new universe in which they're the only one with a memory of this alternative timeline from which they came.
