One of the reasons that humans are so prolific throughout the planet is that we (by the standards of most animals, anyway) can eat pretty much anything. While many other animals have very specialized diets, we can put all sorts of things into our mouths and derive nutrition from them. This allowed humans to travel all of the place and find something to eat just about anywhere. The evolutionary flip side of this is that human nutritional requirements are rather diverse, too. There are things like iron and vitamin B12 that are rare or absent in many plant sources. Of course, nowadays, soy and milk (and soy milk, if you prefer) can provide these essential nutrients too, but soy requires too much processing for non-agricultural people to be able to get any use out of it and the microevolutionary adaptations that let humans digest lactose after infancy are also seemingly only as old as agriculture. This means our early ancestors wouldn't have had any of these alternative sources, and would have -needed- to eat meat. That's why we have those sharp canine teeth, though they're a bit blunted compared to the fangs most true carnivores have.
So, I don't think it's proper to say there is "no biological need," when one thinks in terms of the long-term evolution of the human race. However, nowadays we do have alternative choices, so those who would prefer not to can still have a nutritionally complete (or mostly; there have been some studies saying that children must eat certain amount of meat to ensure proper brain development) diet without it.

No, but being smarter than all of them does, at least by the law of the jungle.

What's to say they won't be just as bad, if not worse?

And my point above was to make the argument that neither could humans, at least talking about early humans living in a "natural state."

No, it doesn't. I disagree with quite a bit of what you've written, but it seems to be quite civil. I'm certainly not going to try to track you down and beat you up for what you believe-- maybe there's hope for our species after all.

Gorillas might look up at the Moon with curiosity, but we built a rocket, stuck some humans in it, sent them there and they walked on it. I think that's pretty amazing.
Oh, me too. I hope you didn't put me in the group that thought humans were pretty much worthless and whatnot, because that's not my view at all. For me, seeing these great things that humans are able to accomplish makes it all the more disappointing that for the most part we still seem unable to overcome our petty squabbles and assorted racism, sexism, and other bigotry, and put all that effort towards accomplishing the great things that we are capable of when we actually put our minds to it. If we (collectively) spent as much effort learning about each other and the world, universe, and so on as we spent in destroying all of those things, we (collectively) would be a lot better off already.
