The reason you have an aversion to eating whole animals is because you can’t distance yourself from the act of choosing to have that animal killed for a delicacy.

When you get a package of meat, most of negative mental impacts of the decision are taken out on slaughterhouse workers, who have tremendously higher rates of depression and anxiety. Put simpler, they have to find ways to deal with the negative emotions that come from the type of work they do.

Thats sort of how paying for stuff always has been, just the distance is father and we’ve figured out how to take the bad feelings and put them on marginalized groups who aren’t us. Bad feelings affect profit.

So if you had to go and point out which animal you want your cut of meat from, you’d likely have the same negative reaction to watching it be butchered as you would putting a whole dead animal in your mouth.
