You are born in a city that has been walled off from the rest of the world, and you've been told your entire life that the outside is dangerous, do you think you would ever visit the outside world?
Would you curiosity win? Or would the fear of death win?

If you've watched Avatar, I'm talking about city like Ba Sing Se, but IRL.
Depends on how the city is run. If it's anything like Paranoia's Alpha Complex, I'd probably die before even getting the chance to think about doing anything treasonous like that
{note added: Prior clones seen as traitors and or mutants. potentially also communists. Do not trust any fellow troubleshooters, you are seen as disposable.]
