During initiation, is it selfish of Tris to crave victory, or is it brave? Do Tris’s friends have a right to be jealous when she’s ranked above them? If you were Tris, would you forgive them for their reactions?

Like an athlete, Tris must make the team or end up factioneless. It's a competition, and she is inherently competitive. Jeaousy is a common reaction, although I do not consider it a right, I consider it a reason to work harder. Tris should ignore their reactions for no other reason than their reactions do not affect her own goals.
