Sure, but just because we relate to them more doesn't affect the ethics of killing other things that are just as alive but are simply less relatable. This has been a strong theme in the progression of civilization.

Ending life to feed our own is how much of nature works, and we have to deal with being a part of that in our ethical thinking, regardless of how associated we are with the life we're ending.

It's simply something to think about: Most people are as flippant about ending the life of a plant, as some are about ending the life of an animal (or various different species of animal, including fish & insects).
