Go back in time and do something to prevent Vasily Aleksandrovich Arkhipov from becoming the Executive Officer on the B-59 Soviet nuclear sub in October 1962. He’s the guy who talked the Captain and the Political Officer out of launching the nukes when they thought they were being attacked by the US Navy during the Cuban Missile Crisis. His persuasiveness is generally considered to have avoided WWIII from starting then.

Procrastinate, the world is going down the drain just fine without my help.

Shoot Arch Duke Ferdinand. Few people even now about it today, but he was subject to a horribly mangled assassination attempt that many scholars belive would have set off a major war in Europe had he died.

I hate the ‘hate’ part (pardon the pun) of the question.

I’d rather go back in time and get Jesus and bring him back here so that he can go all ‘temple money changers’ on today’s MAGA Christians asses, give them a proper yelling to.

Can I appear anywhere? Pop into white house or Kremlin during the Cuban missile crisis and say: I’m from the future, you must attack, or… Then travel back to the future without finishing the sentence.

Go back to 2011ish and unleash WanaCry on a world that is not ready for for a global crypto locker.

Go to back to the big bang. You presence alone will butterfly effect the earth out of existence.

Wait until I’m about to die, then go back to when the first land-dwelling animals first started coming ashore. I’d bring a bunch of cockroaches with me and then I’d die there. Either the roaches or my decaying corpse will hopefully cause enough change to the timeline that humanity never develops in the first place.

I think that’s the most I could screw over the (human) world.

I’d kill Harambe. Wait a second…

Hmm I don’t know. Probably go back to Germany 1940 and give them all the information needed to develop nuclear weapons first. You just know that Hitler would’ve pushed the red button a hundred times over if he had the chance.

Buy a cheap pistol, go back in time, and shoot Gutenberg.

We’d still be living in medieval times.

I’m heading far into the future - say 1000 years or perhaps 100 if communication would be an issue. I’m going to grab all sorts of portable devices and tools to take back with me, and I will maintain the remainder of my life without sharing my goodies. The world is screwed because they get no fruits of my intense labor, but that is fine since I hate them anyway. For that afternoon of work, I get to live a great life while everyone else must suffer in modernity.

My name is Friedrich Trump (aka Frederick Trump) and I already did that and even had a nice hump.
