I'd arrange for Hitler to be accepted by the Academy of Fine Arts in Vienna. His application was denied twice.

I'd travel 9-10 months before he was born and have sex with his mother.. 2 birds, 1 stone.

Go even farther back. 1000 armed soldiers, weapons and fuel and conquer the known world. Introduce sciences, medicines, vaccines. Create a social democratic limited monarchy (you know what's best) and destroy religion and encourage education. Make peace and trading partners in the far east and Americas and Southern Africa. No colonization.

Thinking outside the box: get him accepted into art school.

It's just a joke, but sure why kill him. You could also just abduct him or imprison him all his life. The error that is made here is that Hitler is not seen as a human being but as some evil monster from hell. Without him there would still have been fascists, there would still have been other dictators who could have done the job. The environment that brought us Hitler also brought us a population that supported him and looked the other way when their neighbors got sent to be killed. Killing baby Hitler accomplishes nothing. If you want to make the world a better place try to fight the the evils of today. Hitler is dead, he lost, but racism, bigotry and stupid conspiracy theories are alive and well.

You are not considering what things would be/could be inadvertently changed by your actions in the past. You "change" Hitler, millions more live increasing the current population level in the U.S. and elsewhere resulting in your parents thrust into poverty due to increased competition...you die from malnutrition either as a baby or before being delivered. Another scenario...WWII is averted, Nixon rather than John Kennedy is not elected president. Communists still our enemy, put missiles in Cuba, Nixon orders invasion, Soviet commanders fire their nuclear artillery at the invading American army, which results in a world wide nuclear war. The point being, any change, no matter how small, could change world history, let alone a major thing like changing Hitler's actions would most certainly change what is the norm now.

Imagine this, Hitler grows to be a reasonably sucessful happy painter with a few liederhosen strewn babies and a jolly wife. Oh the while the Eugenisists in UK and US became increasingly more vocal and strident in their views. Bouyed by popular enthusiasm and belief. People like Winston Churchill, Susan B. Anthony amongst many others were great proponents of the Eugenics movement and even by the begining of WW2 were talking about enforced sterilisation of some groups in society. Elizabeth Cady Stanton, an abolitionist, was utterly opposed to black sufferage and in some parts of EU enforced sterilisation continued until the 1970s! Hitler was bound to happen. The mix was already in place, the (poorly gathered) science was there. I suggest had we (like John Lennon suggested) loved and cared for Hitler, someone else would come to the fore. The same as Gadaffi, Osama bin laden and yes even Trump. These people are just wired wrong, the trick is to not be around them when they go off!

I would do neither. Changing the past will change the future in unintended ways. Remember Star Trek the Next Generation and the "Prime Directive". Too bad they didn't listen to wiser people. They kept letting their emotions get the better of them.
"The Prime Directive (also known as Starfleet General Order 1, General Order 1, and the "non-interference directive" ) is a guiding principle of Starfleet, prohibiting its members from interfering with the internal and natural development of alien civilizations"

baby hitler was doomed from the start, with a violent, horrible father and a mom who had lost so many babies that by the time she got to little adolph she was ready to smother him with love and protection. you could not change, with your time machine, her death, which affected him horribly, or his later parkinson's. i'm not saying killing him would change anything either. his rise took place in the perfect storm(trooper) and if it hadn't been he in charge, someone else might have been. (mussolini rose to power without hitler's help, right?) so you probably couldn't change him, and killing him wouldn't have worked. and who KNOWS what other things would've been affected, not all for the better.

if you ever get that time machine, go back and tell the jews who said "what're they gonna do, kill is all?" to get out while they can, or rise up against the nazis. tell the nonjews to rise up, and show them what's going on. neither tactic might work but that would be what to try.

g

You have a bunch of "ifs" regarding his change..."try" and change him..."If" I could guide him...and what IF you couldn't change him or guide him? You wasted a perfectly good time machine and at least 6 million Jews and countless others died because of him...I guess your conscience wouldn't bother you because you tried right? To me the scary question is why you picked poor Hitler, because he's been so misunderstood? You can't come up with any other mass murderers to "save?" Let me guess, your next question is on an Israeli boycott? If you could "change" Charles Manson would you? If you could "change" the KKK would you?---there are good people on both sides you know

Go back and find whoever orchestrated the treaty of Versailles and kill them at birth therefore Germany wouldn’t have become economically oppressed and Hitler wouldn’t have relevant.

Never forget that money is the root of all evil you can either give people too or little but when you do both those with too little will get theirs and that’s when their suffering will be felt by all.

Given what he was capable of, would it be worth the risk? I'd strangle the little shit.

After changing Hitler, I'd change Tr$mp.

Neither by killing or changing him could lead the way to someone far worse

Neither. I'd make sure his parents never met.
Just like I'd make sure 45's parents never met.
If it's just one person, you just make sure their parents never meet.
If the person is never born, they don't need to be changed or killed.

A couple of magic mushrooms in his morning oatmeal would do it.

It's a tough one.

Actually killing a child is horrific - and even with the young Adolph it would still be horrific.

But could he be 'changed'? Maybe or maybe not. If not, of course, then utter horror ensues.

To be honest, if I had a time machine, I would want to travel back even further - and offer Adolph's father a condom.

Hindsight is everything...thank goodness we can't go back...it is interesting to imagine all of the connected lives and events that would ultimately be affected but the scenarios are endless enough to keep writers busy for a bit...

I wouldn't have time to fuck with that shit ? to many fun things to do and find out ? now in answer to the question, change. killing isn't my bailiwick or should I say for forte.

Those are my only two options? I wouldn't do either. If I changed Hitler, something else would have happened instead and it might be better or worse than Hitler. I have no way of knowing and it's not my job to save the world. If I were going to try to change something, it would be circumstances that I know of personally and that I would have a chance of deducting a different outcome to.
