@ymlgarcia Well its just like anything i suppose, we say the word "livestock" or " sheep" ot " chickens" and the truth is a lot more subtle and nuanced than that, for example if you raise your own animals and you get to know them a little, it might be a lot harder for you to kill one animal than another one, because there could be one animal thats a but smarter or has more character, and you can kind of sense its sentience. Similar to if you were an executioner an your job was to execute a group of humans, there might be one in particular that you are familiar with, and you kind of like, and you kind of dont want to execute. Most sentient empathetic humans would probably try to minimize the pain or discomfort that the animal feels when you go to slaughter it. Supposedly this is one of the things that kosher and halal are all about. I heard back in the pre-euro days of maoridom, there were tohungas(doctor,wisemen,witchdoctors, whathaveyou) that were tasked with knowing the most humane ways of strangulation or garroting so when a person got sick with the mate puku or was affected by an illness they could be humanely strangled and their suffering abated. It kind of reminds me of one evolutionary benefit of being a more sensitive human being, that being that the average person tasked with executing someone else or a group of people might not be a clinical psychopath with no empathy, so if you can appeal to that person in the right ways they would probably be more likely to let you live or let you go when their superiors werent looking. If however you show absolutrly no sensitivity or extra sentience, that person probably wouldnt have any compunctions about executing you just like everybody else. This is why i think traits like blue eyes and things survived in evolution. In some cultures they say anything that stands our is bad, though i think in some ways of looking at it, if you stand out, you might be more likely to be kept around as a novelty. For instance the first wolves that were domedticated as dogs were likely the ones that showed extra sentience. This idea also has implications for religion and spirituality. For example if there were superpowerful spirits or gods who could reveal or hide themselves and manipulate the fabric of reality at will, it makes sense that they might only reveal themselves to those who are extra sensitive or sentient. Its the old adage, when a pure vessel receives pure water, it will remain pure. If a dirty vessel receives pure water it will become dirty.
