Looking for a high-fantasy series where the protagonist is disgraced/shunned from a position of high status, gruels (and goes through a life-changing transformation) in hopes of trying to prove himself worthy (first superficial, but then later on realizes that his sense of worth is more about Doing Good and Helping the Common Folk), and then ultimately sacrifices his life for a Greater Cause (The Well-Being of Humanity).
Asking for a friend!
