I don't think it fits a ideology, more like a cult - but the idea of a group that believes life is pain and the universe is imperfect, so the logical course is to kill everyone. Kinda like angry gnostics with more nihilism.
And by everyone, they mean everyone. And everything. Because of the theory of evolution stating that life can arise from chemical reactions, they can't "just" kill everyone. No. They have to destroy the universe to render it unfit for life.
So this leads to some weird group of strangely cheery and scientifically-interested people whose entire cause ammounts to the destruction of all all reality, gleefully studying and working and research and fighting, while singing songs to the end of all life and the universe.
Presuming this is aimed at making non-existing ideologies, I have a weird one.
Essentially, revolutionary confucianism.
The core idea is that power, to be legitimate (in having the mandate of heaven) and strong, requires consistent and constant challenge.
How I see this developing is in a "east asia industrialises first" tl as another approach at liberalesque values. The better versions would promote things like democracy as the constant challenge of the mandate, whilst darker versions form a sort of social darwinism.
The difference is on the onus.How is this different from the ideal of 'rule by the sword' as used by Steppe Nomads? Wherein the ideal ruler is the strong and fearsome, not always the legitimate by birth and so forth. This was effective for creating powerful leaders, especially in martial matters. However, it promoted a persistent instability and requirement for rulers to gain victories against ever more dangerous enemies to acquire needed legitimacy.
I’d note that “patriarchy” (and probably “matriarchy”) refers to a more complex concept in human history than denigrating one gender more than another; “misogyny” captures that kind of thinking better.Hyperpatriarchism = the elimination of cis-women through the development of human cloning via artificial womb and the creation of a single-sex species via deliberate femicide
Hypermatriarchism = the elimination of cis-men through the development of parthenogenesis technology and the creation of a single-sex species via deliberate androcide

I’d also note that killing off all human cis members of a gender isn’t necessarily the same thing as wiping out said gender to the extent that dominant social paradigms (like patriarchy) can no longer function. As an example, if heterosexual women in a society got rid of men, they might replace them with android constructs.
