Imagine if you will, Hitler or a person as evil as Hitler, who instead of crawling into his bunker and dying, goes into his bunker and into suspended animation to return thousands of years later, to meet an exiled human. The being is from a society that is so far advanced, it has done away with war and evil. Imagine also that this other exile can enter the minds of others and is appalled at what he finds in this evil creature. So appalled in fact that he must perform an act totally unknown in the peaceful society he came from.
