Eating animals isn't bad because it "hwurts the poor wittle animals feelings X'("
It's only bad because it's an economical waste (uses about 10x more plant matter, land, water, etc), and the animals that are created aren't living up to their full potential of contributing to the world's ecosystem.
If an alien wanted to enslave you in a cage and eat you, and that was the best thing for the universe, then it would be perfectly ethical for that alien to do that to you. But I'd argue that it would NOT be the best thing for the universe, because as a human, even though you are basically retarded from an alien's perspective, you are still able to work and use the brain you have to contribute to society.
If the higher alien being were to keep you in a cage, your potential to be creative and to do complicated work would be completely wasted, it would be very inefficient to do this as a society, and hence unethical.
