I agree with your point. Even if they are not humans, but some other intelligent living beings, vivisection is not our method. But they could be something completely different, like humans infected with some parasite (recall this photos of persons who entering elite when they appear suddenly with black eye) or something else. That's why I wrote "up to vivisection".
