If David is truly trying to "discover himself" which is in itself a human trait, he will undoubtedly inherit the same failings humans do when then are trying to find themselves.
1) They become the center of the universe. Narcissism in its truest form when you value yourself and your needs above everyone elses.
2) Power corrupts and and absolute power corrupts absolutely. Without a (moral/ethical/programmed) framework to bridle your values, you become empowered to do what is not right in the sight of others.
3) A never ending journey to fulfill your needs. No man is an island and that is true of anyone trying to become one. Without appreciate influence of others, you will spend the rest of your days seek ones own self-gratification without ever truly realizing it.
Wow, that was deep...Sometimes I scare myself...
