== Change to the lead == 

 I made a change that was reverted, left a note on the user's talkpage, but seems he doesn't read his talkpage, so I'll paste the relevant info here too. Khan was not exiled from earth, as the lead said. Following are quotes from TOS:Space Seed. 

  
 At 10:45 into Space Seed, Spock explains why it would be completely illogical to assume these people were exiled in this ship 

 Spock: "If you're suggesting this was a penal deportation vessel, you've arrived at a totally illogical conclusion." 
 Kirk: "Oh?" 
 Spock: "Your earth was on the birth of a dark ages, whole populations were being bombed out of existence. A group of criminals could've been dealt with far more efficiently than wasting one of their most advanced spaceships" 

  
 Here's a quote from Space Seed (20:02 mins in) where he and Kirk are discussing who Khan is: 

 Spock: "By my estimate there were some eighty and ninety of these young supermen unaccounted for when they were finally defeated." 
 Kirk: "That fact is not in the history texts." 
 Spock: "Would you reveal to war-weary populations that some 80 Napoleons might still be alive?"  

 Further quote, from Space Seed, from an exchange between Kirk and Khan (at 25:57) indicating that Khan left on his own. Khan doesn't deny he fled, only denies he was afraid: 

 Kirk: "You fled. Why? Were you afraid?" 
 Khan: "I've never been afraid." 
 Kirk: "But you left at the very time mankind needed courage." 
 Khan: "We offered the world order!" 
 Kirk: "We?" 
 

 There is no indication whatsoever that Khan was exiled AFAIK. I have reverted back to my orginal edit. Please explain how "exiled" could possibly be correct before reverting this edit.
