The vast, vast majority of ethic systems seek the minimization of human suffering as a good, considering it ethical or righteous in some way. Even anti-natalists believe this after a fashion, believing that preventing human beings from being born somehow results in a net reduction of suffering in the world.
However, recently I came across someone who was espousing the opposite belief, arguing that we must increase the net suffering of humanity for the survival of our species. Specifically the argument I heard went like this: most species in nature have their population controlled through a combination of predation and disease. Most species are infested with many species of parasites, and studies have found that removing parasites and diseases from the environment causes their population to explode because it removes their population controls. Similarly, reducing the individual's overall health impairs their ability to find food, find mates, avoid predators, or successfully raise offspring. Environmental stress is also a well-known factor in preventing pregnancies in humans. Humanity's current overpopulation on the planet is because due to technology and societal change we've mostly eliminated most forms of Malthusian population control: war, disease, famine, and predation are becoming increasingly rare, but as a result humanity has become hyper-efficient at stripping all the resources from an area and converting it into human biomass because we are simply too efficient as predators without any natural checks. Therefore, this person proposed that for the long term survival of humanity we must basically return to a state without modern technology where we constantly exist in a state of poor health and suffering from disease, parasites, starvation, etc. to reduce reproductive fitness and cannot access the technology necessary to ameliorate these problems as a constant check on our reproductive rate, else humanity become so efficient that we over-exploit our environment and go extinct.
Now, obviously most would consider this philosophy pretty evil by most definitions of the term and I suspect the individual who said this was an edgy little troll who just wants to see people suffer or else get a reaction, but it made me wonder if there is a name for philosophies that seek to maximize human suffering, rather than minimize it. I tried looking it up but couldn't find any philosophical idea similar to what this person suggested, even though there were some tangential similarities...
- It's not anarcho-primitivism, because anarcho-primitivism argues that returning to a primeval state would be a net good for human wellbeing, rather than a net increase in human suffering. This ideology believes in trapping humanity in a never-ending hellscape from which there is no escape rather than a "return to Eden".
- It is also very specifically not anti-natalism, because anti-natalism believes in the voluntary choice of individuals to not reproduce (e.g., the Voluntary Extinction Movement), and believes that doing so reduces the net suffering of humanity. I have seen some anti-natalists argue for the manual, involuntary abolition of life for those who refuse to follow their ideology and stop reproducing (read: murder), but most anti-natalists seem to consider them nutjobs who miss the point of anti-natalism being about voluntary consent. Additionally, the end goal of anti-natalists is for there to be no humans at all, rather than humanity existing in a constant state of suffering.
- This is also very different from eugenics because eugenics typically argues for the imposition of harm to a select subset of people in the idea that it will promote a greater amount of good for everyone else. Again, this is based on a utilitarian principle of maximizing human wellbeing, even if the selection of who suffers and who doesn't is based on immutable traits.
The closest thing I have been able to find is the fictional trope Dystopia Justifies The Means, in which a character seeks to create a system that maximizes suffering either because they are a manifestation of elemental evil or because they are an extreme misanthrope that wants to inflict suffering on others. Darkseid from DC Comics is perhaps the archetypical example of this, he desires absolute control over all life, but that control is expressed when he gets power through making the populace live in squalor and suffer for the sake of suffering. As expected of the trope, this is both because Darkseid is the anthropomorphic personification of the idea of tyranny and his own personal life is pretty screwed up (both parents were abusive, mother killed his fiance who was his only source of positive emotional support).
Obviously such a philosophy would be horrifying and immoral to most moral frameworks, but I am wondering if there is an actual name for a philosophy that seeks to increase the suffering of humankind beyond "cartoonishly evil".
