The problem with using intelligence as a basis... you can reduce the intelligence of a being -very- easily in D&D... also.. not every human is born sentient...
As for eating itself, no, not evil. Meat is meat.
Heck, I have a (copyrighted) culture of humans that are largely lawful good, who eat their dead as a sign of reverence (and because they don't want grandpa rising as an undead servant of an evil necromancer). The great heroes of the culture come back as ghoul-like creatures, and they raise ravens and other carrion-eating creatures as pets to make sure, if war occurs, nobody has to suffer the indignity of being eaten by lowly maggots, or shambling under the power of your own foes. In D&D terms, the leader of the largest tribe is more or less a paladin.
