LizzieSiddal: He’s not mentally ill otherwise this would have come out at his sentencing.
00100001: Well, what motivated a perfectly sane person to do this??
In the context of patriarchy, Couzens's actions seem sane in the same way that the actions of a honey bee seem sane when it stings an invading hornet to protect the hive even though using its sting will kill it. Couzen's actions had the effect of protecting and reinforcing patriarchy, the evidence is all the renewed bullshit advice for women on how to avoid rape and murder by further restricting our actions. That he ended up in prison himself was collateral. Of course, he didn't consciously murder Sarah "for the patriarchy" any more than a bee thinks consciously of the hive, he acted according to his conditioned misogyny (literally, the hatred of women), a desire for power over a woman as a proxy for women as a class, and the feeling of entitlement sufficient to take it. Under patriarchy, men like Couzens are a feature not a bug: a small number of men (Lisak and Miller (2002) suggest ~6%) have to be conditioned to hate us enough to rape us, and a smaller number to murder us, to perpetuate patriarchy.
Men like Couzens are the kamikaze pilots of patriarchy, they "take one for the team" to keep women in line for men as a class. Elliot Rodgers and similar MRA/incel murderers can be thought of in the same way. You may remember that within days of Rodgers's Isla Vista attack, MRAs were saying publicly that more men would kill women unless women started having sex with submitting to rape by incels.
The actions of Couzens serve to keep women as a class subservient to men as a class, by reminding us of what happens if we try to exist in public or try to say "no" to men's demands.
- When we are too scared to walk home from work and quit our jobs, that job vacancy is freed up for men.
- It's easier for men to abuse us in the home if we are too scared to leave in case we end up like Sarah, "better the devil you know".
- All this "don't walk alone", "don't drink", etc serves to restrict women's movements and so makes more space in bars, workplaces, education, everywhere for men.
- If we are scared that "no" to sex will prompt beating or murder, we say "yes" and open our legs even when we don't want to.
You might have a look at some second-wave feminist literature. Dworkin and Morgan both explain this stuff.
