i hypothesise that worms influence flesh-eater’s brain & behaviour.
it is not uncommon that the worms & eggs from flesh enter the brain and chest of flesh-eaters.
it is a so-called “hidden pandemic”, with many cases in China & USA which are misdiagnosed as brain cancer, lung cancer, flu, coronavirus, mere “headaches”, and more.
just like toxoplasmosis affects cats, i think their brain parasites affect the behaviour of the host to get angry at non-flesh eaters (“vegans”) more, like they drool at the mouth shouting “wHERe dO yOU GeT ProTEiN fROm?!? EaT SoME baCoN mMM BaCoN …” as if i never used to eat steak almost every day?
i think those parasites are influencing them to encourage more people to become hosts of the parasites.
y’all have brain parasites like the RAAJA from “Earth Maiden Arjuna” Anime series.
