I don't have a problem with Wes becoming a Traveler or becoming disaffected with Starfleet, but in the episode they did it pretty clumsily. Making him behave obnoxiously then pulling his abilities out of nowhere with some high minded idea to leave it all alone and let people possibly die.
They could have done the exact same thing, built up his Traveler abilities in the first half of the episode, had Wesley conflicted about leaving Starfleet and made his decision based on that instead of making it about some haughty principle about not protecting people in need.
