Untothislast, thanks for copping to an error, and sorry if I sounded harsh back there.
Raod kill: eat at your own risk. Some people get away with it. Some people get away with not wearing seatbelts or not washing their hands after they poop, and in some parts of the world, people routinely eat animal brains (just say Prions!).
Animals: I'll go further than the chimp example.
I happen to think that most of our food-animals are conscious and have emotional states that we would recognize as being similar to our own. The rationale for this is well-understood neurophysiology plus a rather complicated bit of psychophysics which would be a digression to do in detail here (look up Hameroff & Penrose and start reading and thinking about it).
So, chickens, pigs, sheep, cows, and also rabbits and so on, have feelings and are self-aware. For all we know, fish also have feelings and, above a certain size brain mass, are self-aware to some degree. And yet for most humans, there is some form of meat in the diet, and it's not going to disappear entirely.
In the state of nature we're hunter/gatherers. The hunter part kills animals and eats them. On average (with exceptions such as the Innuit) meat makes up a relatively small percentage of the diet but it is still there. Biologically, we've evolved that way. We do not know enough about nutrition to know that we can take all meat out of the diet without any loss of vital nutrients (that is, we do not know everything there is to know about the nutrients in our diets). There is probably individual variance here, along a normal curve from some people needing no meat at all, to some needing a large amount. (I've found that I can get by with two servings of beef per week, but below that I get run-down and tend to get sick, even when following the best available information re. vegetarian food combining.)
Ideally we will find a way to grow meat in vats: if we can grow organs, we can grow "meat" that is indistinguishable from "the real thing." This would remove entirely the issue of cruelty to animals.
In the meantime, it is incumbent upon us to find ways to slaughter animals that are painless or as nearly so as possible (and by pain I also include the stress of awareness of impending doom). I have a citation somewhere in my files about an academic in Colorado who has looked into this in some detail and developed a "best practices" standard that appears to fulfill this need.
As a practical matter, I can tell you what the discussion in our community-planning group has been in this area. There is a degree of consensus on hunting as a source of meat, particularly in the event of disruption in the conventional meat supply. There has also been discussion of the issue of shooting animals that intrude into agricultural plots (gardens etc.). The latter is an outgrowth of the necessity to protect a food supply from predation by wild critters, for example deer. Clearly it's in a hunter's interest to kill an animal quickly, which is to say, more humanely than otherwise: the better to recover the carcass quickly for processing.
In any case, the cruelty issue isn't relevant to dairy and eggs (nor to wool as a source of fiber for clothing, blankets, etc.). This of course requires that cows and chickens (and sheep) are being kept under humane conditions, which can be reasonably assured in a local production scenario.
