Also, the ability to feel pain does not equal self awareness. Pain is quite the abstract concept, and in reality only serves one simple purpose: To prevent an organism from sustaining damage to itself.
Hell, I'm an amatuer game programmer, and my NPCs feel "pain". When they take damage of any kind, they react defensively in order to not take any more damage. Is it cruel to then destroy them? No, they are not aware of their own existence. They are merely lines of code with an image assigned to them which represents an obstacle of some description.
In a similar way, it is not cruel to kill an entity that is not aware of itself. If I kill a mouse, and it feels pain while I kill it, does it understand the pain it feels? No, it is a mouse. It is a simple organism whose brain only serves the utilitarian purpose of allowing it to control its limbs in order to lead it to food and a mate, which will allow the species to continue. If I kill a cow, is that cruel? In a way the cow is even less aware than the mouse. It has been bred by humans for so long it practically lacks a survival instinct, and its only purpose in existing is not, in fact, to continue its species by reproduction; but to continue it by being eaten, which will give incentive to humans to breed more of its species. This is the truth of the matter, expressed in the plainest of terms.
Also, morality is purely subjective. I shouldn't have to tell you this, but I will anyway. If there were no humans or other capable sentient beings, there would be no morality, therefor morality is a construct of sentience. You control your own morality, you produce it. Others also produce their own moralities as well, and while you may try to influence them by expressing yours, forcing your own morality on someone else is both nonproductive and doomed to fail. Only you can choose your morality, though there are often better choices than others.
OT: Well, look above. I don't really care, and I can even empathize if a person truly dislikes the taste or texture of meat, or if their vegetarianism is for medical reasons. However, people like manic_depressive13 annoy me to no end. Though I'm about 90% sure he's trolling, but if he wasn't, he'd really piss me off.
