No. I guess you refer to debating moral dilemma in your head, but that's only one aspect of morality.
Not all people share the same moral code, but we do expect all human cultures to have a moral code, and we expect humans to act on it's basis, despite their natural instincts and the rather arbitrary moral rules specific to their culture.
