Would this be a bad thing? Humans, created with very long intestines, were designed for fruits and vegetables which take much longer to digest than meat. We were given hands to pick fruit off of a tree. Dogs/cats, however, have very short intestines; they cannot fully digest vegetables/fruit, but can fully digest meat. So, it's not that humans need meat to survive (we were not created to be meat-eaters), but rather that it's a choice of diet..
I take from your frequent use of the word Created, and Designed that you support the idea of biblical creation. If that is the case, then God certainly did intend for us to be meat eaters, even going so far as to dictate the proper way to prepare our meat.
If on the other hand, you are an evolutionist despite your word usage, you have to recognize that factoring all our bodies systems together, we are not evolved as exclusive carnivores, like cats, nor as exclusive herbivores like cattle, but rather as Omnivores like a bear. Our intestines are long enough to digest some juicy fruits and vegetables, but not long enough to digest nor chambered enough for dry grains and fibrous veggies. Our teeth have the canines and pointed molars to tear meat, but also flattened molars and wide incisors for cutting and grinding vegetables. While fruits are certainly the most ideal thing for our intestines, it can cause trouble if that's all we ate because our metabolism is prone to diabetes if given too much fruit, and that factor is even more extreme in high latitude genetic phenotypes such as Siberians, and Inuits who have been diverging from the main human line to become even more dependent on a meat diet, while conversely, Mediterranean people with a long history of agriculture and a good growing climate have been diverging toward being less dependent on meat. If you are the type of person who sits behind a desk all day, with low calorie, and low cholestoral, and low protein needs, you'll probably do okay as a vegetarian, but if you are active and have high physical demands as our primitive ancestors were, and some of us are today, you will not get your nutritional needs through a vegetarian diet unless you take laboratory produced supplements which tend to have lots of other nasty things in them that cause digestive problems like Crohn's disease.
Hunting deer with a gun can cause immediate death w/o alot of pain; however bow-and-arrow hunting should be outlawed. etc. etc..
Getting back to the origin side of things. Hunting is a task that evokes connections with God and Spirituality and the more primitive your methods, the more that connection is enhanced because of the skill required to perform the task. From a biological perspective, why is a heart shot from a bow and arrow immoral, but being gutted by a cougar not immoral. Prey species, regardless of what they are, have no expectation of a quick or painless death, and the sudden death from a distance might actually cause natural selection pressure to make the species less able of dealing with coyotes, wolves, cougars, bears, and other predators. A bowhunter having to approach the animal closer will behave more like a natural predator, and keep the herd fit. You want to outlaw things based on emotional arguments that are not based on logic, natural history, biblical scripture, or normal interspecieal behavior.
