idk why eating it makes it better, but it does, and most people would agree with that. Morality and feelings arent some kind of objective truth u can just find and explain in exact detail. Maybe pleasure derived from eating is more valid because deriving pleasure from just killing something makes it clear that u are crazy and a danger to society, maybe its not that eating it makes it better but that doing it for no reason makes it worse, after all people kill rats and other pests all the time without eating them for the pleasure of not having them around and no one seems to mind.
And u keep saying things like “slaughter of sentient life” (which is a funny way of saying farming but whatever) as if thats somehow wrong but u have never said why it would be wrong.
