4. He Had The Makings Of An Awesome Mad Scientist
For all the times that Wesley ended up saving the day with ideas that really should have been realized by one of the ranking science officers on The Enterprise long before a precocious 15-year old, he also put the ship and its crew in jeopardy nearly as often. Being a boy genius, Wesley had a tendency to do experiments that he had no business undertaking and he would usually do them without any adult supervision. This recklessness would ultimately result in whatever experiment Wesley was working on going haywire and almost destroying The Enterprise or killing his mom. If only one of his screw-ups had actually killed Dr. Crusher or blown Data to bits or made Wesley bald (hey, being bald at 15 is a traumatic event in the life of boy geniuses that can lead one to a lifetime of crime and a seething hatred of flying men in blue tights) so that he could grow bitter and vow to use his overdeveloped brain to wreck havoc all over Federation space. That would have been a heck of a better destiny for the kid than that nonsense with The Traveler.
