    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.

    Well current events lead me to believe that allowing the orange turd to live would do the job nicely so in the spirit of laziness I’d do absolutely nothing.

    Life will find a way. Going back can be used to create nuclear winter but even then, life will go on.

    To completely screw over the world, I would go into the future and acquire the source code for a general AI.

    Then the world can be locked down and robots can be built to abuse every human and sentinent being individually, for a very long time.

    Land the time machine on top of the first animal to walk on land. Don’t even have to get out of the machine.

    Go back from 2026 to 2024. Report a pet has gone missing and you heard that an immigrant neighbor ate it. Come back to 2026. Book your dream vacation at the Trump Gaza resort.

    The biggest killer for indigenous people is said to be infections - bacteria and viruses. Collect some in this time - maybe a cold - and go back and presence will be enough.

    It depends on how you interpret “screw over the world”, but I guess “you hate everyone” implies humans. If you go back to the first humans from Africa, before spreading out, that may have the biggest impact - significant delay or suppression in development and spread, or eradication.

      Go back 1000 years before Europe makes contact with the Americas. Infect everyone and let their populations get wiped out, but give time to recover so first contact with Europe doesn’t go as poorly. Also give them horses much earlier.

    Go back to the stone age and drop modern steel tools and weapons where a tribe could find them. That tribe would likely become dominant and perhaps change everything.

      Your plan fails and the proletariat rise up and seize the weapos. You return back to a world of gay space communism.

    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.
