    Belgian Congo/Jewish Holocaust is right up there. I wouldn't say a specific person but innumerable people involved.

    King Leopold and Hitler were THE authority, so ultimately they signed off on the death and suffering of millions of Congolese and Jews (and other minorities) respectively.

    For the Congo: imagine a father staring at the severed hand and foot of his five year old daughter. That's a photograph searchable online, and needs to be seen to understand the violence and dehumanism of colonialism.

    For the holocaust: we have all seen at least one picture. But imagine a baby being smashed against a wall because it wouldn't stop crying. Pretty women (maybe even underage girls) being raped. To say just a small part of the atrocities of the holocaust.

    Well, I haven't even included Unit 731. General Shiro Ishii.

    Now, what to say about today in 2026? Who's to say these atrocities are not being repeated?

    Hitler and king Leopold are great answers. The things they perpetrated are very difficult to stomach. I consider myself someone who is fairly desensitized, especially growing up during the wild west of the internet. Unit 731, though? I can't. Absolutely the most vile humans to have walked the face of the earth. Humans aren't born good or evil, but rather have potential for either. The fucking shitstains of unit 731 found a way to maximize the human capacity for evil. Naming anyone in that group is the correct answer.

    While Hitler, Pol Pot, Beria, and Kissinger are all good and obvious contenders, I think these will be surpassed by someone who is alive right now.

    But who? Well, it's most likely someone who already has significant resources at their disposal. For all their flaws, I don't think the lizards of Amazon, Google, OpenAI, and Facebook have much of an agenda beyond growing their fortunes. But I am convinced we haven't seen the final form of Peter Thiel.

    Thomas Midgley, Jr

    Invented CFCs like Freon, which caused the hole in the ozone layer, and then later went on to pioneer the use of lead in gasoline, which is estimated to have resulted in the cumulative loss of millions of IQ points from humanity during its use, not to mention lead-derived cancers and other illnesses.

    Possibly the single greatest negative contribution to the environment and humanity.

    The effects of lead poisoning were already very well known, 8 people died of lead poisoning at DuPont during the development and Midgely himself suffered the effects of lead poisoning after "proving" his compound was safe in a public demonstration.

    He absolutely knew there would have been widescale negative health effects if they continued to push the product on the market. He also knew about widely available alternative "anti-knocking" agents they could have used but they were unable to be patented and so there was no profit.

    He is absolutely a case of someone who simply did not care about the consequences of his work beyond what profit could be extracted.

    CFCs are a slightly different issue because no one could have reasonably anticipate their effects on the atmosphere and he was long dead before those effects were starting to be felt.

    I don't believe he would have stopped developing them even if he did know however.

    The universe got the last laugh however after he became entangled in self made contraption to help him after he developed polio, suffocating him.

    To address both you and the person below you: he deliberately gave himself lead poisoning on national television by inhaling the concentrated vapor of leaded gasoline for over a minute. He did this not because he was ignorant of the health dangers of lead (he had already had lead poisoning TWICE BEFORE), but because he was purposefully misleading the public.

    Surgeon General Shirō Ishii (Japanese: 石井 四郎, Hepburn: Ishii Shirō; [iɕiː ɕiɾoː]; 25 June 1892 – 9 October 1959) was a Japanese biological weapons specialist, microbiologist and army medical officer who served as the director of Unit 731, the largest biological warfare and chemical warfare unit of the Imperial Japanese Army.

    Ishii led the development and application of biological weapons at Unit 731 in the puppet state of Manchukuo during the Second Sino-Japanese War from 1937 to 1945. This included the Battle of Changde, the Kaimingjie germ weapon attack, and the planned Operation Cherry Blossoms at Night biological attack against the United States, which intended to spread a weaponized bubonic plague. Ishii and his colleagues also engaged in human experimentation, resulting in the deaths of thousands of subjects, most of them civilians or prisoners of war.

    Ishii was later granted immunity in the International Military Tribunal for the Far East by the United States government in exchange for information and research for the U.S. biological warfare program.

    I think that where we are today, it's more important than ever to really recognise that there is absolutely no "evilest" person. And moreso, almost all of them genuinely believed they were being a force for good.

    The main reason for there being no "evilest" is because there are not just tens, or hundreds, but thousands of people who have committed horrific atrocities which even as individual acts would be in contention for the evilest.

    Just within the Holocaust, you have so many individuals perpetrating such evil. The croatian fascist groups always stick out in my memory for the raw personal brutality.

    However, there are so many comparable situations throughout history that we know very little about. Sacking of cities, mass rapes, Jeffrey fucking epstein, what's been happening in Sudan, what happened in Ethiopia a few years ago, the Holocaust, the Mongols, the ottomans, the British empire, south American dictators, the Japanese empire, the russian empire, the soviet union, al Qaeda, the Taliban, ISIS, the IRA, the Vikings, and on, and on, and on.

    Yes, arguments can be made about how much more evil things are when they are organised etc. However, in my mind, organisation is just a tool that we have improved. We need to be hyper vigilant that anyone, at any time can end up being so radicalised that they are willing to perpetrate evil. Including ourselves. We are not really different from these evil humans.

    There's a difference, now, though:

    Humankind's doing its "mitosis" thing.

    Humankind is dividing-by-alignment.

    That only happens 1x per world, ttbomk.

    ( after the original Industrial Revolution, the Roman Empire, then the "seedling" that that was, in our world eventually grew into a "sapling", the official Industrial Revolutions-sequence..

    then, as population reaches ecological-saturation & technology simultaneously reaches world-breaking power, ClimatePunctuation kicks-in..

    etc

    all eventually enforce The Great Filter.

    & in that Great Filter, alignment polarizes.

    Anti-Life polarization & With-Life polarization.

    Every world of people-similar-to-our-kind would have to go through it, same as "puberty", but for whole-species )

    As the process progresses, the polarization is going to become more & more extreme.

    So, until now we've been mixtures, every individual ( with few exceptions ), but .. that's going to be changing, until there's zero mixture left, & everybody ( near the end of this century ) is absolutely-polarized, 1 way or the other.

    I don't believe that. Sociopathy is extremely common in those that achieve high levels of power. Most of them used and manipulated others credulity around things being forces for good to increase their own power. For such people getting what they want is their only real criteria for good.

    While that is true, I think that many of the most successful at building a following are true believers. Hitler is a pretty good example.

    I think Mao or Pol Pot also started out quite idealistic and then we're warped by power.

    I suppose it's very difficult to really say one way or the other, and I would argue that true evil is only possible when the intent is purely self serving.

    Even with sociopathy, they may genuinely think they are doing good without feeling empathy for those they harm. However, it's a very good point that many of those that rise are sociopaths or become sociopathic.

    I'm seeing that people aren't having a good objective framework for judging evil, so here's my dimensions-of-evil, including the stuff in DarkTriad & DarkTetrad:

    • narcissism
    • machiavellianism
    • sociopathy/psychopathy ( to this point is DarkTriad )
    • sadism ( to this point is DarkTetrad )
    • nihilism
    • displacing objectivity
    • displacing correct-reasoning
    • displacing evolution/growing from a life, or from lives
    • displacing autonomy with puppetry/authority

    The more dimensions of evil, the worse.

    The stronger on any dimension, the worse.

    Ancel Keys established a spurious link between cholesterol and heart disease. His Seven Countries Study was an early application of regression analysis. What is very rarely mentioned was that Keys omitted 5 countries (more? Can't exactly recall) that didn't fit the regression he wanted to show. (Ref: "Good Calories, Bad Calories," Gary Taubes)

    Keys' contributions to lipid hypothesis fucked the metabolic health of millions for decades.

    Regarding Keys' centenarian expiration, go find a pic of what that dude looked like for the last few decades of his life. I'll pass on the longevity and his diet plan.

    And if you're interested in how nutritionally screwed we are in the US:

    • "Hacking of the American Mind" and "Sugar" by Robert Lustig, a Harvard endocrinologist

    Ok, so, regarding these ideas:

    • "it has not been revealed enough how damaging sugar is" -- I would agree with this. I'm not sure that was his intention in particular.
    • Ancel (intentionally?) overlooked some data when forming his theory -- I would agree with this too. But it doesn't make the harm of cholesterol moot. Or do you now want to ignore the other data yourself? It just makes the situation more complex than simply "fat alone is bad". Too much fat is still bad.

    He made a step, perhaps a bit too long in a mistaken direction, but understanding didn't and won't stop with him. How everyone reacted to his theory was also part of the fault.

    He made a step, perhaps a bit too long in a mistaken direction, but understanding didn’t and won’t stop with him. How everyone reacted to his theory was also part of the fault.

    These are excellent points and spot on. We're all looking for the silver bullet and elevator pitch, even those of us who know better. "Oh, just stop eating fatty meat, eggs, and salt!" Except it's way more complex than that. To Keys' credit, he also highlighted the importance of weight management/obesity, cardiovascular health, and "regular" exercise. The definition of "regular" of course keeps getting modified.

    Too much fat is still bad.

    Agreed, although too much of anything is bad. "The toxicity is in the dose." Keys pushed replacing saturated fats with PUFAs, which became a whole different problem with industrial PUFAs becoming the norm. Industrial PUFAs are high in Omega-6 EFA while being low in Omega-3 EFA. Humans don't actually need any digestible carbohydrates to survive, but we very much need fats and protein to live. Nutritional research has merely been negotiating on where the borders are.

    But it doesn’t make the harm of cholesterol moot. Or do you now want to ignore the other data yourself?

    We worry too much about exogenous cholesterol, when endogenous cholesterol is the real problem. Cholesterol is a lot like that joke about the guy looking for his keys in the middle of the street. "Did you lose your keys around here?" "No, but this is where the light is." Cholesterol, especially back when nutrition policy was being set, was what we could easily measure, and that was a correlation that science pursued. Epidemiological studies are notoriously tricky, sometimes just a step above anecdote. And to discuss these things in any serious detail requires a couple book-feet of text, most of it being contextual qualification.

    Regarding the importance of cholesterol as a risk indicator: What's probably closer to the truth is balance of HDL to LDL and cholesterol to HDL, with triglycerides being a case-by-case basis. If I recall correctly >500mg/dL being the absolute level for concern and interventions, with >200mg/dL being considered abnormally high.

    I think in the end, we all have to find what works for us at our given point in life. Because no silver bullet and there's no way to discuss these things simply and quickly.

    I believe the current view on LDL is that its level what the body needs it to be and generally doesn't require intervention. However, the Tg/HDL ratio is a reasonably good indicator of your metabolic health. OTOH Tg should be below 100 mg/dL, and ideally it should be lower than the HDL reading. The ratio of Tg/HDL should be below 1.8, using mg/dL.

    Cholesterol has not been scientifically established to the cause of heart disease in human beings. It was based on a study that was done on rabbits fed cholesterol and vegetable oil. The ensuing focus on low-fat diets has caused in my opinion an untold amount of suffering, including my own NAFLD.

    But ya know what has been proven to contribute to heart disease, atherosclerosis, dyslipidemia, NAFLD, hyperinsulimia/Type 2 diabetes, and chronic inflammation? Refined carbohydrates (Taubes, Lustig, et al).

    I kinda understand the downvotes because we've had 50+ years of saturated fat fearmongering. But when you start digging into this long running, test-in-production experiment on human diet and health, it's hard to avoid conspiratorial thinking.
