You actually provide me with an opportunity to make clear what I meant. I think I meant a couple of things, actually.
I guess I have to confess, I was partly inspired by Star Trek, and Vulcans, specifically. Vulcans have no emotions. Now, I am not saying there could be an alien civilization with no emotions. But what about just, say, less emotions, or more blunted emotions? This actually would make a good thread in itself (can a humanoid civilization exist, where the “people” have no emotions?).
I also was envisioning an advanced being that is less-compassionate and less caring than us. Reptiles, I think (at least on earth), are often like this, in my opinion, at least. Again, though, I have to wonder if they wouldn’t just annihilate themselves, with nuclear weapons, or even just genocide. But as many of you have suggested, or at least alluded to, I am just using earth and human values when I say this.
