Is eating meat ALWAYS wrong?

There are many reasons to become vegan. The environment, health, ethics, et cetera. I became vegan on a purely ethical basis, however I see no reason to refrain from eating meat that hasn't been factory farmed (or farmed at all). Suppose you came across a dead squirrel in the woods after it fell from a tree. Would it be wrong to eat that wild squirrel (that for the sake of the argument, will not give you any disease)? Or is eating animals always wrong despite the circumstance?
