...if he was a bit more patient? TOS' "Space Seed" depicted a Khan Noonien Singh as "brilliant", but his arrogance proved to be his downfall. He should have bid his time to make his move. Or better yet, just petition the Feds for clemency, then set up shop on a colony if he was to opposed to integrating with normal society. Maybe if Khan was not such an ego-maniac, he could have used his brilliance to re-direct the Federation into something he could control. BONUS: What if Khan turned good? Meaning, based on pure altruism, what could Khan do to make humanity, and this the Federation, better? How would the TNG era turn out?
