How is Gene's hatred born out of his fear, envy, and sense of inferiority? Explain how it is in man's nature to hate a person they envy or think...

Gene and Phineas have a close but complicated friendship.
As told from Gene's perspective in The Separate Peace, Gene spends
much of the story struggling to understand what he truly feels about Phineas and why he
feels that way. His feelings change often as experiences reveal new layers of their
relationship.

Phineas is a natural athlete and a
charismatic leader among their classmates and friends. Gene envies the athletic ability
he can not equal - teenaged boys in that setting (and most humans, in most settings)
don't like to be beaten.

However, Gene is the better
student, and he consoles himself with his superiority in that area. When Gene
understands that Phineas can accept, and indeed expects, Gene to achieve superior marks,
his sense that their relationship is balanced is deeply
shaken.

He had
never been jealous of me for a second. Now I knew that there never was and never could
have been any rivalry between us. I was not of the same quality as he. I couldn't stand
this.
