I find it important that ethical inhibitions are not absolute. Sure, they feel absolute, but history shows they aren’t nearly as absolute as they feel. Even if we (tentatively) accept that our moral inhibitions are an adaptation, it seems probable that our ability to violate them is also an adaptation. Finally, what worked in an ancestral environment is not guaranteed to work now. In short: even if ethical inhibitions evolved as described, it doesn’t follow that obeying them is a good idea.
