The Death Note lets you kill anyone by writing their real name in the notebook, although you must know their face.

I'm going back to the like 1780s and going full John Brown.

I have a special and unique hatred for Diego de Landa, burner of the Mayan books. I would remove him and as many of his associates as possible from history.

[–] Hadriscus@jlai.lu 3 points 2 weeks ago* (last edited 2 weeks ago)

That's a great pick, damn ! fuck that Diego guy

Can I throw in Vespucci and/or Colombus as well ?

Quick, find Donald Trump's family tree and start pruning the old branches

[–] trxxruraxvr@lemmy.world 14 points 2 weeks ago (2 children)

Could do the same with Hitler, Stalin, Pol Pot and other dictators. Juist kill one person in each one family tree and see how it works out.

Earthdivers is a graphic novel. In the future, a group of Native Americans discover time travel and decide to use it to fix the mistakes of the past. First problem is Columbus.

Orson Scott Card did something along these lines in the book Pastwatch.

His whole bloodline. I'd do the research, and make sure I get his family tree.

Ooh, looks like Emperor Constantine was just smote by a thunderbolt from a clear blue sky in full view of the entire senate.

Maybe we won't be spreading that cult he liked around, seems like it pissed off Jupiter something fierce.

[–] ivanafterall@lemmy.world 7 points 2 weeks ago (6 children)

Same idea, except I'm going all the way back for ol' Abe. And I don't mean Lincoln. Important clarification nowadays.

Probably not an outcome I would want for the world but out of scientific curiosity I would be interested in what happens if Ögedei Khan dies of old age instead of drinking himself to death in December 1241, just before his army has the chance to completely steamroll Europe. That might be one of the most extreme butterfly effects in history.

But all the people I want to kill is alive now, that is unfair.

Charles Babbage and Ada Lovelace were on the verge of inventing computers back in the 1820s.

I'd like to see what happens when I get them to suceed.

[–] gajahmada@awful.systems 11 points 2 weeks ago (3 children)

How do you suppose to achieve this with a Death Note?

[–] Postmortal_Pop@lemmy.world 4 points 2 weeks ago

That's just the backup

[–] ozymandias117@lemmy.world 3 points 2 weeks ago

Not OP, but you can control people before their death, so... Probably write other people around them and force them to help before their suicides?

[–] DagwoodIII@piefed.social 2 points 2 weeks ago

I'm in 1820 with all my knowledge of the future.

I don't need the Death Note.

[–] IronBird@lemmy.world 4 points 2 weeks ago* (last edited 2 weeks ago) (2 children)

alexander the great, indirectly probably kills just about every western despot after him and we'd all be speaking mongolian probably

[–] luthis@lemmy.nz 2 points 2 weeks ago (1 children)

I doubt it. No one speaks Latin now.

[–] IronBird@lemmy.world 3 points 2 weeks ago* (last edited 2 weeks ago)

alexander dies christianity and the roman model never spread across europe, all of christiandom dies in it's crib (note, havent actually looked at the history of this all that closely).

catholism never takes off and we don't have the HRE or any of it's bastard children. no german empire, no french, no english, no protestants spreading to the new world etc.

[–] TheWeirdestCunt@lemmy.today 2 points 2 weeks ago

Tbf Alexander already died at a pretty young age, he was only in his 30s afaik.

[–] sexual_tomato@lemmy.dbzer0.com 3 points 2 weeks ago

Doesn't matter what era.

First, before using the death note, publish everything you know about the future and its tech. For example, even if you barely remember the periodic table, filling out anything you remember about it would significantly expand humanity's understandimg at the time. Describing protons, neutrons, electrons, photons, quarks, positrons, neutrinos, bosons, etc would be a century or more ahead of its time. Knowing about radiation at all would save tens of thousands of lives from suffering just from avoidable exposure deaths.

Any modern common knowledge about germ theory, DNA, cell biology, virus structure, or the idea of antibiotics would be revolutions at the time. Just knowing penicillin comes from mold would save millions of lives, not to mention the isolation of stuff like insulin.

Asserting the existence of the photoelectric effect (photodiodes, solar panels), piezoelectric effect (phone haptics, timing crystals), the thermoelectric effect (any digital thermometer), and remembering that computer chips have something to do with silicon puts us ahead 100 years technologically. Knowing the best batteries are made mostly of lithium and something else puts us 100 years ahead in battery tech.

Knowing that rubber is supposed to be black leads to the discovery of vulcanization early and saves us from decimating the whale populations.

Knowing there are massive oil deposits in the middle east, Texas, Canada, and Mexico, or massive gold/diamond/steel/copper deposits in various areas makes nations supremely wealthy instantly after they extract resources.

For our purposes, though, photography need to advance drastically. If you know this is coming and have time to prep ahead of time, you learn everything you can to hasten the invention of the photograph.

Then you get to work with the death note.

In general: you start eliminating the elite class in whatever country you're in. Slowly, so as not to create a power vacuum that destabilizes the nation.

Because of your scientific predictions that keep coming true, elites keep wanting to meet you to see if you can make them richer. That's how you gather catalogs of faces.

Once your country moves to a strong collectivist government (socialist, communist, whatever) whose officials are chosen by true random sortition, you move on to the next one. Obviously you may have to do things out of order if there's an imperialist military threat to your country, but that's the idea. Keep society invested in the sciences and engineering to advance living conditions for all.

I'm in the US, so I'd focus on the immediate halt of the slaughter of native Americans. Oregon is already a state, so we'd still likely pick up idaho and Wyoming.

That'd probably result in an independent nation of natives in California, arizona, New Mexico, and Oklahoma. Oklahoma absorbs the Texas panhandle as a result.

A separate native nation forms in the Dakotas and Montana.

I'm not sure of statehood sentiment after that; it's likely the Dakotas/Montana vote for statehood as a single state rather than multiple territories- they're landlocked, so would become a vassal state to the surrounding countries (Canada, usa).

Next, tackle the US' existing slavery and apartheid systems. The civil war is over, but slavery still exists in the form of Jim Crow laws and such.

The next hurdle to cross is the rampant corruption inherent in the system. This era already had a great deal of progress- antitrust legislation primarily. I shepherd these movements along and make them stronger.

At the end of my life, from 1900-1920, (I'm 36, going back to 1876, so I'd be 60-80) I make sure to eliminate the political figureheads that destabilized Europe throughout the early 1900s. It's important to stabilize what is now the EU.

Been a long time since I've seen the anime...but can't you schedule deaths for in the future?

I've been on a deep dive about Mormonism, so I'm gonna say Joseph Smith. Yknow, earlier than he was actually killed.

Just for curiosity sake, kill both Marie Antoinette and Louis XVI some time in their life long before coming into power.

I would need to know, though, whether, considering we are already bending the books rules by killing already dead people, I could get away with looking at a portrait/painting/whatever of a person and use it to kill their younger self.

Because otherwise, I would probably kill Napoleon just for fun. No other reason than to have the history books say he climbed into a loaded cannon and was shot out with the cannonball.

Hernan Cortes and Francisco Pizarro were distant cousins so that person.. between the two though I think Pizarro was worse

[–] redsand@infosec.pub 2 points 2 weeks ago

I don't need the deathnote just a tablet with a bunch of books downloaded. Good fucking luck stopping me 🫡

[–] leave_it_blank@lemmy.world 2 points 2 weeks ago

I kill myself. If I have learned anything from books and movies, it's that you don't fuck with time travel.

[–] Apytele@sh.itjust.works 2 points 2 weeks ago* (last edited 2 weeks ago)

Athanasius of Alexandra.

Too fucking easy.

Honestly I'm not even against trinitarianism there probably is something special about the number 3 as often as it shows up in world religions and philosophies but getting dedicated enough to it to develop imgroups and outgroups to start killing people over it was way outta pocket.

Christianity was way better when it was an antiimperialist death cult.
