Let's say that a virus spread throughout the world and damaged the areas of the brain that are responsible for emotions. The entire population was affected and could no longer experience any emotional reactions, although their reason and intellectual ability was unimpaired.
Would morality change if we no longer have any emotional reaction to cheaters, thiefs, inequity, or tragedy?
Maybe it's difficult to answer such a hypothetical, but any opinions would be appreciated.
Emotion-less or emotion-free creatures/beings have been explored in science fiction, including Stanley Kubrick's "2001" and "Star Trek." See what Wikipedia says about the 1956 B&W movie, "Invasion of the Body Snatchers," at http://en.wikipedia.org/wiki/Invasion_of_the_Body_Snatchers .
